03DD41574249352EFC99FA0063A1433B.taxon	description	The species is similar to P. acuminata, but distinguished by the oblong-ligulate petals not widened near the middle and the transversely elliptic lip widest well above the base. — Type: S. Achá et al. 149 (holo LPB), Bolivia, La Paz, Prov. Bautista Saavedra, Área Natural de Manejo Integrado Apolobamba, Chaka, campamento. alt. 3625 m, 27 Mar. 2009. Etymology. Dedicated to Alfredo Fuentes, collector of the type specimen. Plant c. 19 cm tall, leafless during flowering. Scape erect, terete, apically glandular-puberulent, with 5 tubular, acuminate sheaths. Inflorescence racemose, 3 - flowered, rachis glandular-puberulent. Flowers yellowish white. Floral bracts c. 8.5 mm long, elliptic, acuminate, externally glandular-puberulent. Pedicellate ovary c. 9 mm long, densely glandular-puberulent. Dorsal sepal c. 5.5 by 2.8 mm, ovate, subacute, externally densely glandular-ciliate, 3 - veined. Lateral sepals c. 5.7 by 2.3 mm, obliquely ovate, acuminate, externally densely glandular-puberulent, 3 - veined. Petals c. 6.2 by 1.2 mm, free, oblong-ligulate, obtuse, glabrous, 3 - veined. Lip c. 5 by 7 mm, cucullate-concave, transversely elliptic in outline; apical lobe oblong-ovate, papillose, recurved; disc almost glabrous, primarily 7 - veined, veins branching, ornamented with a few rounded glands along the margin in the upper half. Gynostemium c. 3.1 mm long. Distribution — Endemic to Bolivia. Habitat & Ecology — Terrestrial at the altitude of 3625 m among shrubs near ‘ páramo yungueño’, which is characterized by the dominance of high grasses. Flowering: March. Note — Unlike P. acuminata (Fig. 3), the petals of this Bolivian species are not widened near the middle and the lip is transversely elliptic (vs reniform), widest well above the base. In P. multiflora (Lindl.) Schltr. (sect. Acraea) petals are adnate to the dorsal sepal and ciliate along the margins. Moreover, in the latter species the upper margin of lip’s lateral lobes is ornamented with numerous small glands (c. 20 – 30 on each lobe vs up to 10 on each side). This species is only known from the type.	en	Kolanowska, M., Baranow, P., Nowak, S., Fuentes, A. F. (2020): New species and a new record of Pterichis sect. Pterichis (Orchidaceae) from Bolivia.

Gynostemium c. 3 mm long. Distribution — Endemic to Bolivia. Habitat & Ecology — Terrestrial in very wet areas near paramo yungueño as well as on moss-covered rocks at the altitude of 3090 – 3150 m. Flowering: April. Note — This species is similar to P. galeata (Fig. 5) and P. leucoptera Schltr. (Fig. 6), but it can be distinguished by the oblong-lanceolate, sparsely ciliate petals (vs glabrous, elliptic above linear claw). Pterichis galeata was the first species described within Pterichis and it is broadly distributed in Andean countries (Colombia, Ecuador, Venzuela, Peru, Bolivia) and in Costa Rica. The morphological variation of this species prompted Morales (1986) to divide it into two varieties based on the inflorescence (length, number of flowers), but the general flower characteristics, e. g., unguiculate petals and auriculate lip base are consistent between populations. Pterichis leucoptera is a somewhat enigmatic species known from very few collections but according to Schlechter (1921) it differs from P. galeata mainly in the plant size. Also, the lip auricles in P. leucoptera are not conspicuous like in P. galeata and petals are subequal in length to the dorsal sepal (vs petals longer than dorsal sepal in P. galeata). More Peruvian collections should be made to verify the actual separateness of these two species. In the Bolivian P. mandonii (Rchb. f.) Rolfe (sect. Acraea), petals are glabrous (vs sparsely ciliate in P. lunatilabia) and distinctly widened near the middle (vs oblong-lanceolate in P. lunatilabia). In P. mandonii the broad middle lobe of the lip only slightly exceeds the lip’s lateral lobes (vs much exceeding lateral lobes in P. lunatilabia).	en	Kolanowska, M., Baranow, P., Nowak, S., Fuentes, A.

Habitat & Ecology — Terrestrial in cloud forest, within shrubs and dispersed young trees and in high montane, wet forest at the altitude of 3100 – 3580 m. Flowering: February, April. Notes — This species strongly resembles P. acuminata (Fig. 3) from which it can easily be distinguished by the oblong-ligulate petals, which are not widened near the middle and the lip being obcordate in outline, widest near the base of the apical lobe (vs lip reniform, widest near the base in P. acuminata). Moreover, the flowers of P. acuminata are reddish brown or reddish green while in the new species the petals are whitish and the lip is yellowish with brown stripes. In P. multiflora Eponymy.

Gynostemium c. 3 mm long. Distribution — Endemic to Bolivia. Habitat & Ecology — Terrestrial on moss-covered rocks at the altitude of 3400 m. Flowering: April. Notes — Species similar to P. acuminata (Fig. 3), but distinguished by the lip being lunate above the truncate base (vs lip reniform in outline in P. acuminata). Pterichis vasquezii resembles P. leucoptera (Fig. 6) in which petals are widest in the apical third (vs oblong-lanceolate, widened near the middle in P. vasquezii). Moreover, the novelty differs from the latter species also in the prominent truncate base of the lip. A similar, broad-truncate lip base is observed in the Bolivian representative of sect. Acraea, P. mandonii, which differs from P. vasquezii by the petals being adnate to the dorsal sepal (vs free in P. vasquezii) and a broad, short middle lobe of the lip that only slightly exceeds the lip’s lateral lobes (vs much exceeding lateral lobes in P. vasquezii). The type material consists of four plants, one of which has a leaf.	en	Kolanowska, M., Baranow, P., Nowak, S., Fuentes, A. F. (2020): New species and a new record of Pterichis sect.

03DD4157424D3529FFD6FC5E67E041E7.taxon	description	Pterichis yungasensis Schltr. (1922) 37. — Type: O. Buchtien s. n. (US? – not localized), Bolivia, La Paz, Unduavi, July 1907. Plant about 40 cm tall, leafless during flowering. Scape erect, terete, apically glandular-puberulent, with 5 tubular, acuminate sheaths. Inflorescence racemose, laxly few-flowered, rachis glandular-puberulent. Floral bracts c. 13 mm long, elliptic, acuminate. Pedicellate ovary c. 13 mm long, densely glandular-puberulent. Dorsal sepal c. 9 by 4.5 mm, ovate, obtuse, externally densely glandular-puberulent, 3 - veined. Lateral sepals c. 9 by 4.9 mm, obliquely ovate, obtuse, externally densely glandular-puberulent, 3 - veined. Petals c. 13 by 4 mm, free, ba- sally ligulate, apical half elliptic to lanceolate, obtuse, glabrous, 3 - veined. Lip c. 7 by 12 – 14 mm, cucullate-concave, reniform in outline, base truncate; apical lobe oblong-triangular, papillose, recurved; disc minutely papillose, 13 – 15 - veined, ornamented with numerous rounded glands along the margin. Gynostemium c. 3.5 mm long. Distribution — Endemic to Bolivia. Habitat & Ecology — No data. Notes — When Schlechter (1922) described the Bolivian en- demic P. yungasensis, he compared it to Peruvian P. leucoptera (Fig. 6). The latter species is characterized by a sublunate lip produced into an oblong apical lobule. Other similar species are P. acuminata and P. galeata. However, unlike in P. yungasensis, the petals of P. acuminata (Fig. 3) are widened near the middle (subrhombic in outline). Pterichis yungasensis can be distinguished from P. galeata (Fig. 5) by the lack of prominent lip auricles (such auricles are observed in P. galeata). Vasquez et al. (2014) referred to the specimen Vásquez C. 2491 as representative of Bolivian P. yungasensis, which should be deposited in herb. Vásquez, but we did not find this plant in the collection. The type specimen collected by Buchtien has been not localized in US or any other visited herbarium. In the course of the study we found some unnumbered collections made by Buchtien but none of these was collected in the area where the type of P. yungasensis was found. Also none of Buchtien’s examined specimens did fit the morphological characteristic of this species. For that reason here we refer to Schlechter’s illustration and description of P. leucoptera.	en	Kolanowska, M., Baranow, P., Nowak, S., Fuentes, A. F.
