J. V. Alves & N. G. Silva 2017	<div><p>Vellozia fontellana R.J.V.Alves &amp; N.G.Silva, sp. nov.</p> <p>Vellozia fontellana differs from V. crinita by the taller stature and hemispheric shrubby habit (vs. grasslike, cushion-forming) (Fig. 2), erect profusely branched caudices; caudex diameter 15–25 cm (vs. 40 mm); leaf sheaths sparse on caudex, exposed, not splitting into fibers (vs. densely packed on caudex, early-splitting); stalked-capitate emergences distally secreting oil-resin covering the hypanthium (Fig. 3 A, B), apical one third of pedicel, abaxial side of outer tepals, along abaxial midrib of inner tepals, style and abaxial side of stigma lobes (vs. linear subulate, 3–4 mm long non-secretory emergences on hypanthium (Fig. 3 C, D) and vestigial on pedicel); Stamens 18, basally connate with tepals (vs. 15, free from tepals), filaments roughly the same length as anthers (vs. much shorter) (Fig. 1); linearly oblanceolate tepals (vs. broadly lanceolate) growing on exposed north-facing outcrops (vs. growing under half-shaded south facing overhangs in outcrops). Differential character states for V. fontellana and V. crinita are provided in Table 1 and Figs. 2–4.</p> <p>Type:— BRAZIL, Minas Gerais: Parque Estadual do Ibitipoca, crista da trilha para a Cachoeira dos Macacos, 21 o 42’ 49.65”S, 43 o 53’ 37.65”W, 1276 m alt., 15 April 2016, R.

R. Sadala-Castilho 1 (R!).</p> <p>Complemented diagnosis of V. crinita:— [the original description text by Goethart &amp; Henrard (1937: 368) is in italics]: Small [cushion-forming] subshrub [to 10 cm tall excluding live leaves]. Caudex very short, thickened, ovoid, densely covered by leaf sheaths. Leaves [soft membranous] subrosulate, up to six [8] per rosette, erect to patent, the external ones persisting (marcescent) and reflexed, all curved, canaliculate to subcomplicate, linear and attenuate almost from the middle, narrowly carinate, sulcate on both faces, margins of the keels rather densely adpressedly serrate, the serrature grading in to long white hairs which gradually become shorter toward the apex, the apices very narrowly rounded, 20 × 0.5 cm. Sheaths very broad, broadly ovate, apex rounded and dividing into curved dark matte fibers, sulcate. Flowers subterminal, solitary, pedunculate, medium-sized, lilac-colored. Peduncles filiform, trigonous, basally glabrous, from the middle nearly covered by very short, narrowly linear, flattened, rather tortuous scales with acute apices, gradually becoming longer toward the apex. Ovary [hypanthium] obovate, with a truncate apex, densely covered by scales similar to those of the peduncle but much longer (up to 4 mm). Tepals [in two whorls, broadly lanceolate], ca. [24] 35–50 × 10–15 mm [abaxial side and margins of outer whorl covered with linear, acute, non-secretory emergences; inner whorl eglandulose, about 2 mm wider than outer], apices obtuse and mucronulate. Stamens [15 in six whorls alternating 2 and 3!, shorter than the tepals, attached to hypanthium]. Anthers linear [15–17 mm long!] filaments, filiform [arched, 2–4 mm long!]. Style about 1½ times longer than the stamens. Stigma broadly 3-lobed, peltate. Capsule [dry, loculicidal, with persistent filiform oil-resin glands, brown]. Brazil: Summit of the Serra de São José d’El Rey, on the rock outcrops. 15 December 1886. Flowers lilac-colored. GLAZIOU no. 16388. Type (L!), registered under 912.180—543. [V. crinita is known only from the type locality: the São José massif in the municipalities of Coronel Xavier Chaves, Lagoa Dourada, Prados and Tiradentes (21 o 4’ 26.6”S, 44 o 9’2.62”W), and from the nearby Lenheiro massif in São João Del Rei. In both localities it grows restricted to half-shaded southward cliff overhangs and slopes between 1000 and 1400 m alt. It flowers profusely in the peak rainy season (December– January) and again in mid-winter (May–July) when dew precipitates copiously in the early mornings.]</p> <p>Material of V. crinita studied: — BRAZIL, Minas Gerais, Tiradentes, Serra de São José [Del Rei]: 15 December 1886, On rock summit, Glaziou 16388 (holotype L!; isotypes K!, NY!, P!); ibidem, January 1896, Alvaro Silveira 1275 (R!); ibidem, 1 August 1965, A.
