(Figs. 1 and 2).</p> <p>Diagnosis— Beauverdia hirtella subsp. glabrata is distinguished from B. hirtella subsp. hirtella by its glabrous leaves (vs. papillosepubescent), with narrower blade (0.2–0.8 mm vs. 0.9–2 mm wide), glabrous scapes or with scarce 1-celled trichomes with uncinate cell (vs. scapes densely covered by 1-celled trichomes with a single straight cell) and nearly spherical or obovate capsules (vs. obovate or obovate-oblong). From B. hirtella subsp. lorentzii differs by its erect-ascendant leaves (vs. patent-recurved), with glabrous and narrowly linear-filiform blade, 0.2–0.8 mm wide (vs. papillose-pubescent, 2–5 mm wide), nearly terete or broadly elliptic in crosssection (vs. flat or slightly convex), scapes glabrous or with few 1-celled trichomes with uncinate cell (vs. scapes densely covered by 1-celled trichomes with straight cell) and nearly spherical or obovate capsules (vs. obovate-oblong).</p> <p>Type: — BRAZIL.

São Gabriel, RS 630, à direita da Estrada, após o cerro do Graxaim, 2 June 2018, L.P. Deble et al. 19244 (PACA!).</p> <p>Phenology:— Flowering time May–June, fruiting time June–July. The flowers open around midday and close in the late afternoon, withering after two or three days.</p> <p>Distribution and habitat: — Beauverdia hirtella subsp. glabrata was found in Dom Pedrito, Lavras do Sul and São Gabriel municipalities, in south-central Rio Grande do Sul state, Brazil. The plants grow on rocky grasslands, mainly volcanoclastic rocks of the formation Acampamento Velho and granitic rocks of the formation Santa Maria (Sommer et al. 1999, 2011). This region is the most diverse in number of taxa of Beauverdia in Brazil, having in addition to this new subspecies, the occurrence of B. dyalistemon, B. hirtella subsp. hirtella, B. felipponei and B. vittata. B. hirtella subsp. glabrata and B. hirtella subsp. hirtella can be found sympatrically near the urban area of Dom Pedrito municipality, in a location called “Serrinha”, which corresponds to the northern limit of geographic distribution of the subspecies hirtella. In this location the subspecies hirtella occurs in deeper soils and associated with cespitose grasses, among the grasslands, while the subspecies glabrata stays restricted to concavity of rocks, which occur in a mosaic within these grasslands. During our field study, intermediate forms between both subspecies were not observed. Beauverdia hirtella subsp. glabrata displays its bulbs developed in the concavity or directly above of the rocks, associated with mosses, others herbaceous angiosperm species, and the lycophyta Sellaginella selloi Hieronymus (1900: 306). In the same environments of occurrence of B. hirtella subsp. glabrata many others bulbous were registered, including the Iridaceae Calydorea riograndensis Deble (2011: 36), Cypella fucata Ravenna (1981a: 18), Cypella pusilla (Link &amp; Otto 1828: 125) Jackson (1893: 689), Herbertia darwinii Roitman &amp; Castillo (2008: 311), H. lahue (Molina 1810: 110) Goldblatt (1978: 379), H. pulchella Sweet (1829: pl. 222), Herbertia sp., Kelissa brasiliensis (Baker 1877: 134) Ravenna (1981b: 106), and Onira unguiculata (Baker 1892: 72) Ravenna (1983: 204), some Oxalidaceae, as Oxalis perdicaria (Molina 1782: 146) Bertero (1829: 739) and O. sellowiana Zuccarini (1831: 198), and several others Amaryllidaceae, mainly of the genera Nothoscordum and Zephyranthes, among them Nothoscordum collinum Ravenna (1989: 41), N. gaudichaudianum Kunth (1843: 458), N. minarum Beauverd (1908: 1001), N. muscorum Ravenna (1991: 41), N. ostenii Beauverd (1908: 996), Zephyranthes bifida (Herbert 1825: pl. 2597) García &amp; Meerow in García et al. (2019: 492), Z. caerulea (Grisebach 1879: 320) Baker (1888: 37), Z. gracilis Herbert (1837: 172), Z. flavissima Ravenna (1967b: 28), Z. minima Herbert (1837: 172), and Z. tubispatha (L’Heritier: 1788: 6) Herbert (1821: 36).</p> <p>Conservation: — Beauverdia hirtella subsp. glabrata is known only from four localities, and the populations spread in an extension of occurrence lesser than 5,000 km ² and area of occupancy smaller than 500 km ². The subspecies occurs in specific habitat, as it only grows on rocky grasslands, mainly volcanoclastic rocks and granitic rocks, and the bulbs develop in rocky concavities. These environments are being modified by economic activities, as mining and agriculture. The urban expansion and the invasion of exotic species in the region of occurrence of the subspecies, notably “capim-anonni-2” (Eragrostis plana Nees von Esenbeck 1841: 390), an exotic invasive species native to Africa, result in a direct threat to this taxon. In accordance with the criteria of IUCN (2019), Beauverdia hirtella subsp. glabrata can be considerate Endangered (EN), based on direct threat, geographic distribution, occupation area and population size (EN B1+B2ab (i, ii, iii) + c (ii, iv) + C1+C2a (i), b).</p> <p>Discussion: — Beauverdia hirtella subsp. glabrata is easily recognized by its bulbs and scapes with strong alliaceous smell, narrowly linear-filiform and erect-ascendant leaves, with glabrous blades, scapes glabrous or with scarce 1-celled trichomes with uncinate cell in the distal third, and flowers with perigone composed by golden-yellow tepals. Beauverdia hirtella subsp. glabrata is morphologically close to both currently recognized subspecies of B. hirtella, since all these taxa have alliaceous smell and flowers with similar shape and size, and perigone composed by golden-yellow tepals (Fig. 3). However, B. hirtella subsp. glabrata is distinguished from B. hirtella subsp. hirtella by its glabrous leaves (vs. papillose-pubescent), with narrower blade (0.2–0.8 mm vs. 0.9–2 mm wide), scapes glabrous or with scarce 1-celled trichomes with uncinate cell and 60–90 µm long (vs. scapes densely covered by 1-celled trichomes with straight cell and 110–180 µm long), and nearly spherical or obovate capsules (vs. obovate-oblong or oblong). The new subspecies is easily differentiated from B. hirtella subsp. lorentzii, due its erect-ascendant leaves (vs. patent-recurved), linear-filiform blade, 0.2–0.8 mm wide (linear blade, 2–5 mm wide), nearly terete or broadly elliptic in cross-section (vs. flat or slightly convex), flowers composed by six tepals (vs. eight tepals), and nearly spherical or obovate capsules (vs. obovate-oblong or oblong), and the same pubescence features mentioned to distinguish from B. hirtella subsp. hirtella. Additional features to distinguish the subspecies of Beauverdia hirtella can be assessed in Table 1.</p> <p>From others species in the genus, B. hirtella subsp. glabrata clearly differs in several aspects. From B. dyalistemon the new subspecies contrasts by its strong alliaceous smell (vs. absent), erect-ascendant leaves (vs patent or patentrecurved), narrower leaf blade (0.2–0.8 mm vs 1–5 mm wide), sulcate or nearly terete in cross-section (vs. flat or slightly convex), golden-yellow tepals (vs. light yellow), and stamens with adnate filaments at their bases (vs. free). B. hirtella subsp. glabrata distinguishes from B. felipponei by its strong alliaceous smell (vs. absent), erect-ascendant leaves (vs patent or ascendant-recurved), with 0.2–0.8 mm wide (vs. 1–5 mm wide), and tepals oblanceolate or broadly elliptic in shape (vs. lanceolate or elliptic-lanceolate). Beauverdia hirtella subsp. glabrata is readily distinguished from B. vittata by its erect-ascendant leaves (vs. ascendant or ascendant-recurved), blades with 0.2–0.8 mm (vs. 1–4 mm wide), flowers with golden-yellow tepals (vs. white), oblanceolate or broadly elliptic in shape (vs. lanceolate or elliptic-lanceolate), and stamens with adnate filaments (vs. free).</p> <p>By its general aspect, B. hirtella subsp. glabrata is very similar to Nothoscordum setaceum (Baker 1871: 381) Ravenna (1968: 58), considering the leaves with glabrous and narrowly linear-filiform blade and size and shape of scapes, and fruits. However, B. hirtella subsp. glabrata can be immediately recognized by the larger size of the flowers, the shape of the tepals (oblanceolate or broadly elliptic vs. lanceolate or elliptic-lanceolate) and the stamens with filaments adnate at their bases (vs. free). Nothoscordum setaceum is an enigmatic species, given that the location of the type collection is doubtful and because it is known only from a single herbarium voucher. This species was recognized under Ipheion by Traub &amp; Moldenke (1955), and as Nothoscordum by Ravenna (1968). More recently, it was considered a doubtful species of Beauverdia, or even a possible valid name for B. vittata (Sassone et al. 2014a). Beauverdia subsessilis is another taxon which must be compared with B. hirtella subsp. glabrata, since this species is glabrous and was mistakenly included in the synonymy of B. hirtella (Deble unp. data); however, in B. subsessilis the alliaceous smell is absent (vs. present), the bulbs emit lateral rhizomes (vs. bulbs without rhizomes) and its leaves display 0.9–2 mm wide, and are flat in cross-section (vs. leaves 0.2–0.8 mm wide, nearly terete or broadly elliptic in cross-section). Nothoscordum marchesii Crosa (2005: 254) is another taxon similar with B. hirtella subsp. glabrata, due the strong alliaceous smell and narrowly linear-filiform and erect-ascendent or erect leaves, with up to 0.8 mm wide. However, B. hirtella subsp. glabrata can be easily distinguished by its bigger flowers (16–24 × 7.5–10 mm vs. 8–15 × 4.5–8 mm), golden-yellow colored (vs. white-cream), and larger outer tepals (11–15 × 4.5–7 mm vs. 10–12 × 4–4.5 mm) and inner tepals (10–14.5 × 4–6.5 mm vs. 8–10 × 4–4.5 mm).</p> <p>Other materials examined:— Beauverdia hirtella subsp. hirtella.
