512CB34B0910FA50CC97FE075D7547B1.taxon	distribution	Distribution and habitat: — Fosterella atlantica is known from the type locality only, from the county of Matutina, west of Minas Gerais state, situated in the so called mesoregion of “ Triângulo Mineiro-Alto Paranaíba ” (fig. 1). It is the first species of Fosterella recorded in Southeastern Brazil, representing the most eastern point of distribution of the genus. The population of this species was originally located and documented by the research team of the Prístino Institute located in Minas Gerais state, Flávio F. do Carmo, Luciana H. Yoshino, and the botanical taxonomist Rubens Custório da Mota, who provided the first field records on this new species. Fosterella atlantica grows along the river Pirapetinga, in partially shaded sites, as a saxicolous or more often as a terrestrial on clayey soils amidst glauconite rocky outcrops (figs. 7 A, B, C), locally known as “ verdete ”, which is a green colored, potassium sulphate and magnesium sulfate rich rock typical for the region. Flowering was documented in August and September.	en	Leme, Elton M. C., Forzza, Rafaela C., Halbritter, Heidemarie, Ribeiro, Otávio B. C.

512CB34B0910FA50CC97FE075D7547B1.taxon	etymology	Etymology: — The epithet refers to the geographical outlier range of F. atlantica in the southeastern Minas Gerais state, much closer to the Atlantic Ocean than any other species in the genus, which are traditionally known from a western distribution in Central Brazil, not distant from the border with Bolivia and Paraguay, except for a single Amazonian species. Observations: — The trichome type on the abaxial surface of the leaf blades and petal curvature clearly indicate the closely morphological affinity of F. atlantica to F. windischii. However, the new species differs from it by the entire leaf blades (vs. inconspicuously and subdensely spinulose at the base), inflorescence usually with primary branches and rarely with inconspicuous secondary branches (vs. with distinct secondary branches), primary bracts many times shorter than the stipe of the branches (vs. the basal ones longer than the stipe), inconspicuous white lepidote to glabrescent (vs. densely and coarsely white lepidote), flowers shorter (7 – 8 mm vs. 7 – 10 mm long), with shorter pedicel (1.5 – 2.5 mm vs. 1.5 – 4 mm long), sepals shorter (1.5 – 2 × 1 – 1.5 mm vs. 2 – 3 × 1.5 mm), vinaceous toward the apex (vs. greenish), petals vinaceous in the central-apical portion mainly abaxially (vs. white), apex obtuse (vs. acute), and forming an apically rounded flower bud before anthesis (vs. flower bud with an acute apex). It is interesting to mention the pollen of this new species has sulcus margins well defined but not sharply cut, bearing microreticulate exine elements decreasing in size, but without any entire marginal area, while in F. windischii pollen has sulcus margins sharply cut and bearing a distinct entire marginal area without microreticulate exine elements. In addition, F. atlantica has the eastern-most range for the genus, in Minas Gerais state, southeastern Brazil, while F. windischii is known from the western region of Mato Grosso state, central Brazil, close to the border with Bolivia, as well as further western from Bolivia, in the Depto.

512CB34B0910FA50CC97FE075D7547B1.taxon	distribution	Distribution and habitat: — According to the collector, F. batistana was found growing as a saxicole in a very humid site, near Curuá-una waterfall, in the middle of the Amazon forest. The place of collection is about 400 km from the city of Santarém, which is situated in the confluence of Tapajós and Amazonas rivers, not far from the border with the State of Amazonas. There is a specimen deposited in IAN herbarium (J. B. Fernandes da Silva 1227) indicating a collection from the region of Rio Urucu, Coari, Amazonas state. However, according to the collector, the indicated origin is probably a labeling mistake, since as far as his memory is concerned, he left a living specimen of Fosterella then with the IAC curator, but it was really collected in Serra do Cachimbo, situated south of Pará state on the border with Mato Grosso State. The very humid habitat of this new species may explain its very delicate leaf texture, which is thinly subchartaceous to submembranaceous toward the apex. An additional specimen collected in Jacareacanga, Pará state, has an unusual epiphytic habit (João Batista Fernandes da Silva, pers. com.) for the first time reported for the genus, which is possibly an adaptation to periodically floaded sites in Igarapé forest in the Amazon region.	en	Leme, Elton M.

512CB34B0910FA50CC97FE075D7547B1.taxon	etymology	Etymology: — The epithet of this species honors the collector of the type specimen, the Amazonian orchid specialist, João Batista Fernandes da Silva, who has discovered countless new species. Observations: — Fosterella batistana can be distinguished from all Brazilian species by the combination of its geographical range restricted to Amazonian region, its small stature, flowering 15 – 30 cm tall, the broad leaf blades 3 – 5 cm wide, which are distinctly narrowed toward the base but not petionate, glabrescent or sparsely covered by peltate, dentate, white trichomes of the type III, inflorescence axis and floral bracts sparsely lepidote with filamentous trichomes. In the protologue, Peters et al. (2008 b) pointed towards the close morphological affinity of F. batistana to the Andean F. weberbaueri (Mez) L. B. Smith (1960: 172), known from Bolivia and Peru, which shares the same type of leaf trichomes. The close relationship and distinctness as well, is corroborated by molecular data based on four chloroplast DNA regions (Rex et al. 2009). Besides its clearly distinct geographical range, F. batistana differs from F. weberbaueri by its acaulescent habit (vs. subcaulescent), smaller stature when in bloom (15 – 30 cm vs. to 90 cm tall), leaf blades sparsely lepidote to glabrescent (vs. glabrous adaxially only), and by the shorter inflorescence (6 – 18 cm vs. 25 – 30 cm long), which is sparsely white lepidote (vs. glabrescent).	en	Leme, Elton M.

512CB34B0914FA4DCC97FA3B5D2E46D1.taxon	etymology	Etymology: — The epithet refers to the county of Bodoquena, in the state of Mato Grosso do Sul, where this new taxon was discovered. Observations: — Specimens of F. bodoquenensis are relatively common in herbarium collections despite almost always misidentified as F. hatschbachii. Using the identification key provided by Ibisch et al. (2008) F. bodoquenensis keys out close to F. penduliflora. On the basis of the morphological delimitation of F. penduliflora provided by Peters (2009), this new species differs from it by leaf blades densely lepidote abaxially with peltate, long fimbriate trichomes (type II) [vs. sparsely lepidote, with peltate, dentate trichomes (type III)], inflorescence bearing secondary branches (vs. with primary branches only), primary branches more numerous (16 – 20 vs. 6 – 15 in number), as well as by the shorter floral bracts [1 – 2.5 mm vs. 2 – 4 (– 10) mm]. When using the identification key presented by Peters (2009), F. bodoquenensis is morphologically closer to E. elviragrossiae, but differs from it by taller stature when flowering (85 – 95 cm vs. up to 35 cm tall), leaf blades glabrous adaxially (vs. lepidote towards the base), peduncle bracts equaling to exceeding the internodes (vs. much shorter than the internodes), inflorescence shortly paniculate (vs. racemose or compound racemose), with secondary branches (vs. with primary branches only), primary branches more numerous (16 – 20 vs. to 3 in number), longer sepals (2.5 – 3 mm vs. ca. 1.5 mm long), and longer petals (7 – 8 mm vs. 4 – 5 mm long). According to trichomes (type II) architecture of the abaxial surface of leaf blades of F. bodoquenensis it is closer related to F. elviragrossiae (trichomes of type II) than to F. penduliflora (trichomes of type III). However, based on other morphological differences, this new species is easier differentiated from F. elviragrossiae than from F. penduliflora, as indicated above. 4. Fosterella hatschbachii L. B.

512CB34B0914FA4DCC97FA3B5D2E46D1.taxon	distribution	Distribution and habitat: — The known populations of F. hatschbachii are concentrated in the district of Pirapuranga, municipality of Aquidauana, in Mato Grosso do Sul state, where it grows in usually vertical, sandstone rocky outcrops, in shaded places inside forest vegetation, very often along or nearby rivers, at 200 – 250 m elevation (figs. 10 A, B, C). Plants thrive isolated (fig. 10 B) or more often forming dense, small to large groups of individuals (fig. 10 C).	en	Leme, Elton M. C., Forzza, Rafaela C., Halbritter, Heidemarie, Ribeiro, Otávio B.

512CB34B0914FA4DCC97FA3B5D2E46D1.taxon	etymology	Etymology: — The epithet honors its collector, one of the most remarkable Brazilian field botanists and discoverer of countless taxa, Gert Hatschbach (1923 – 2013), founder of the Museu Botânico Municipal de Curitiba, to which he dedicated a life-long time. Observations: — In the protologue of F. hatschbachii, Smith & Read (1992) clearly indicated as its holotype, the specimen collected by Hatschbach 30497 in the state of Mato Grosso do Sul (at that time part of the state of Mato Grosso), in the locality of Piraputanga, Aquidauana county. The designated holotype is deposited in the herbarium of the Smithsonian Institution (US) and isotypes are in the herbarium of the Museu Botânico Municipal de Curitiba (MBM) and Herbarium Bradeanum (HB), the last one not cited in the protologue. Smith & Read (1992) also cited three other specimens (paratypes): one collected in Mato Grosso do Sul state, at the type locality (Piraputanga, Serra de Maracaju, Hatschbach 25757), and two other ones [Hatschbach 37652 (MBM, US), and Prance et al. 19368 (INPA, NY, U, US)] from Chapada dos Guimarães, Mato Grosso state, distant 570 km in straight line from type locality. The comparison of the type material, as well as other specimens from the type locality, with the specimens from Chapada dos Guimarães, Mato Grosso state, including Hatschbach 37652 and Prance et al. 19368, indicate the presence of morphological differences important enough to segregate these two mentioned specimen as a distinct species, well apart from F. hatschbachii, as described below.	en	Leme, Elton M.

512CB34B0909FA4FCC97FB125DD44A5E.taxon	distribution	Distribution and habitat: — This new species is endemic to Chapada dos Guimarães, Mato Grosso state, where it grows on vertical sandstone outcrops (figs. 11 A, B, C), in shaded or partially shaded sites inside the forest, nearby or along rivers and waterfalls, at 465 – 800 m elevation. It forms small groups of numerous plants that in the driest season are difficult to locate due to the leaves that dry toward the base, causing the leaf rosettes to almost disappear.	en	Leme, Elton M.

512CB34B0909FA4FCC97FB125DD44A5E.taxon	etymology	Etymology: — The name of this species is based on the word “ Lilliput ”, a fictitious island populated by tiny people in the novel “ Travels into Several Remote Nations of the World. In Four Parts. By Lemuel Gulliver, First a Surgeon, and then a Captain of Several Ships ”, better known simply as “ Gulliver’s Travels ” by Irish writer Jonathan Swift, being a reference to the distinctly small stature of F. lilliputiana. Observations: — This new species is closely related to F. hatschbachii, differing from it by the distinct smaller size of the plants (8 – 35 cm vs. 42 – 75 cm high), leaf blades shorter and narrower (13 – 20 × 0.5 – 2 cm vs. 25 – 50 × 1.6 – 3.7 cm). Using the terminology proposed by Peters (2009) for Fosterella trichomes, the abaxial portion of the leaf blades of this new species is white villous or tomentose with multifilamentous-stellate trichomes (vs. tomentose with subpeltate, long filamentous trichomes). It is important to mention that Peters (2009) reported “ stellate trichomes ” for F. hatschbachii but this character was observed by her on the specimens from Chapada dos Guimarães, Mato Grosso (i. e. F. lilliputiana), which she examined, while the specimen of F. hatschbachii from the holotype locality (i. e., Piraputanga, Mato Grosso do Sul), were only examined by her by means of photographs. Other differences of F. lilliputiana when compared to F. hatschbachii are the inner leaf blades with margins densely lepidote with multifilamentous-stellate trichomes (vs. margins glabrous or with peltate, long dentate trichomes), shorter peduncle (5 – 17 cm vs. 20 – 38 cm long), inflorescence simple or with no more than second order branches (vs. up to third or fourth order branches), and shorter (2.5 – 14 cm vs. 12 – 30 cm), and by the shorter primary branches (2 – 10 cm vs. 6 – 16 cm long). In cultivation, both species become proportionally larger when fertilized, keeping however the distinctiveness. Fosterella lilliputiana lives in higher altitude areas when compared to F. hatschbachii, which can be found in distinctly lower elevated habitats, 200 – 250 m, in Mato Grosso do Sul state.	en	Leme, Elton M.

512CB34B090CFA47CC97FF6A5F09444D.taxon	distribution	Distribution and habitat: — According to Peters (2009), F. penduliflora has the broadest geographical distribution in the genus, growing in Peru (the type collection only), Bolivia, and Argentina, with some registered Bolivian populations thriving about 210 km, in straight line, from Brazil’s border. There is only one collection now reported (and examined) from Brazil, in Rondônia state, about 550 km apart, in straight line, from the known Bolivian populations. In Brazil, the cited specimens were found growing on a hill 280 – 300 m elevation, saxicolous on rocks inside the forest, along a waterfall. It was reported as an abundant species when it was collected 36 years ago. However, an expedition organized few months ago with the specific purpose to locate it did not succeed, probably because the area is now severely affected by cattle breeding and periodical fires.	en	Leme, Elton M.

512CB34B090CFA47CC97FF6A5F09444D.taxon	etymology	Etymology: — The name of this species is an explicit reference to its pendulous flowers. Observations: — The absence of living specimens for deeper observation of floral characteristics and the presence of leaf trichomes of the peltate, dentate type III, documented by SEM images (figs. 3 M, N, O) encourage us to identify the specimens from Rondônia, at least provisionally, as F. penduliflora on the basis of the identification key provided by Peters (2009). However, the specimens from Rondônia (e. g. fig. 12), when compared to the Bolivian specimens and to the lectotype (fig. 13), in the morphological circumscription of Peters (2009), present some discordant features, like leaf blades subdensely lepidote (vs. laxly lepidote) with margins densely lepidote along the basal portion (vs. glabrous), upper peduncle bracts shorter than the internodes (vs. equalling to longer than the internodes), and inflorescence with third order branches (vs. with second order branches only). In comparison to the other Brazilian species, F. penduliflora is closer related to Amazonian F. batistana, with which it shares the same peltate, dentate trichomes (type III), despite distinctly sparsely arranged in F. batistana. Other differences of F. penduliflora are its larger size when in flower (40 – 60 cm vs. 15 – 30 cm high), longer peduncle (20 – 36 cm vs. 5 – 15 cm), longer inflorescence (24 – 40 cm 6 – 18 cm), longer primary branches [(6 -) 11 – 22 cm vs. 2 – 8.5 cm], and longer pedicel (2 – 6 mm vs. 1 – 3 mm). 7.

512CB34B090CFA47CC97FF6A5F09444D.taxon	distribution	Distribution and habitat: — Fosterella windischii is growing saxicolous on sandstone rock outcrops and rock walls along rivers and near waterfalls (figs. 14 A, B), within the humid forest, in the region of the Parque Estadual Serra de Ricardo Franco, in the municipality of Vila Bela da Santíssima Trindade, in the west region of Mato Grosso state, close to the border with Bolivia, at 500 – 640 m elevation. It is also reported by Ibisch et al. (2008) and Peters (2009) from Bolivia, where it grows in the Parque Nacional Noel Kempff, not distant from Brazil’s border, at lower altitudes. The region of Serra de Ricardo Franco is known by its rich biodiversity due to the confluence of different ecosystems, like the Amazonian, Cerrado, and Pantanal.	en	Leme, Elton M.

512CB34B090CFA47CC97FF6A5F09444D.taxon	etymology	Etymology: — The name of this species honors its collector, the Brazilian botanist, Paulo Gunter Windisch, specialist in ferns and lycophytes. Observations: — Fosterella windischii is an easy-to-identify species within Brazilian species, due to its very characteristic combination of morphological features: leaf blades abaxially completely covered by a thick and coarse layer of white, interwoven peltate, shortly fimbriate trichomes (type I), abaxial and adaxial faces strongly contrasting in color, margins inconspicuously and subdensely spinulose at the base, inflorescence with distinct third order branches, basal primary bracts longer than the stipe, which are densely and coarsely white lepidote, sepals greenish, petals strongly recoiled-recurved at anthesis and afterwards, white with acute apex, pollen with sulcus margins sharply cut and bearing a distinct entire marginal area without microreticulate exine elements. Despite the 1600 km separating, in straight line, the Brazilian population of F. windischii, situated in the west region of Mato Grosso state, from the population of its close relatives, F. atlantica, in Minas Gerais state, their morphological proximity is evidenced by the trichome type on the abaxial surface of the leaf blades and petal curvature at anthesis and afterwards. However, F. windischii differs from it by leaf blades inconspicuously and subdensely spinulose at the base (vs. entire), inflorescence with distinct third order branches (vs. usually with second order branches and rarely with inconspicuous third order branches.), the basal primary bracts longer than the stipe (vs. many times shorter), being densely and coarsely white lepidote (vs. inconspicuously white lepidote to glabrescent), flowers longer (7 – 10 mm vs. 7 – 8 mm long), with longer pedicel (1.5 – 4 mm vs. 1.5 – 2.5 mm long), sepals larger (2 – 3 × 1.5 mm vs. 1.5 – 2 × 1 – 1.5 mm), greenish (vs. vinaceous toward the apex), petals white (vs. vinaceous at the central-apical portion mainly abaxially), apex acute (vs. obtuse), and forming a flower bud with acute apex before anthesis (vs. flower bud apically rounded), and pollen with sulcus margins sharply cut and bearing a distinct entire marginal area without microreticulate exine elements (vs. sulcus margins well defined but not sharply cut, bearing microreticulate exine elements decreasing in size, but without any entire marginal area). According to Peters (2009), considering the non Brazilian species, F. windischii is similar to F. kroemeri Ibisch, R. Vásquez & J. Peters (2008: 189), endemic to Bolivia, differing in its shorter and narrower leaf blades with more pronounced indumentum on the abaxial leaf blade surface, shorter peduncle and the less branched inflorescence. 8.

512CB34B090CFA47CC97FF6A5F09444D.taxon	etymology	Etymology: — The epithet honors the Bolivian zoologist Yuvinka Gareca, for her ecological research in the area of Santiago de Chiquitos. Observations: — Fosterella yuvinkae is closely related to F. hatschbachii and can be easily confused with it. However, it differs from it by leaf blades abaxially densely white tomentose with long multifilamentous-stellate trichomes (type IV) [vs. subpeltate, long filamentous trichomes (type V), which are more densely arranged], primary branches with a higher number of flowers (20 – 35 vs. 10 – 27 in number), sepals acuminate (vs. acute), and by the longer petals (9.5 – 10 mm vs. 7 – 9 mm long), white (vs. whitish or whitish with a pale reddish-wine colored central-apical portion), and acute apex (vs. obtuse and inconspicuously cucullate-emarginate). When compared to the non Brazilian species, Peters (2009) indicates it is close to F. penduliflora, distinguished from it by the densely tomentose abaxial leaf surface, with trichomes type IV [vs. scattered lepidote with peltate, dentate trichomes (type III)], narrower petals, and the distinct habitat preference in Precambrian rocky outcrops within Chiquitano-Dry-Forest of Bolivia (vs. widely distributed in montane Andean forests in Bolivia, as well as in Peru and Argentina).	en	Leme, Elton M.
