description: 6. Pauridia trifurcillata (Nel) Snijman & Kocyan (2013: 30). Figs. 3A & 14   
 Bas.:— Ianthe trifurcillata Nel (1914b: 297) ≡ Spiloxene trifurcillata (Nel) Fourcade (1932). Type (lectotype designated by Snijman & Kocyan 2013: 30):— SOUTH AFRICA. Uitenhage [QDS: 3325CD], 350 ft [107 m], 14 April 1893, R. Schlechter 2490 (BOL!, isolectotypes, WU! [image], Z)   
Plants 8–15 cm tall. Corm more or less ovoid, 8–15 mm diam., covered by fine, brown, fibrous tunics; fibres reticulate, firmly attached to basal disc, slightly spreading distally, tips shortly acuminate; cormlets sometimes produced near base; roots slender, mostly straight, arising from corm proximally. Cataphylls membranous, persisting as a dark brown, papery neck up to ca. 15 mm long. Leaves 5–8, sheathing proximally for up to ca. 25 mm, more or less recurved, narrowly lorate, 100–180 × 2–4 mm, carinate, pale green, thin-textured, margin entire. Inflorescences 1 or 2 in flower at a time, (1)2-flowered, slightly shorter to longer than leaves; scape 30–60 × 1 mm, somewhat compressed laterally, pale green; bracts 2, clasping pedicels at base, linear, 10–15 × 0.5 mm, translucent with pale green midrib. Flowers pedicellate, stellate, yellow, rarely white, backed with pale green in both whorls, unscented; pedicels suberect, subterete, 15–80 × 1 mm, spreading when fruiting, pale green; tepals (4)6, sometimes slightly reflexed, narrowly elliptic to oblong-lanceolate, 5–9 mm long, outer 2.5–3.0 mm wide, mucronate apically; inner 1.5–2.5 mm wide. Stamens 6, equal or outer slightly shorter than inner, suberect to slightly spreading, yellow; filaments inserted on ovary rim, outer 2.0– 2.5 mm long, inner 2.5–3.0 mm long, shorter than or equalling anthers; anthers oblong, latrorse 2.0– 3.5 mm long, basal lobes up to 0.3 mm long, apex emarginate, yellow; pollen yellow. Ovary narrowly obconical, ca. 3.0 × 1.5 mm, 3-locular; style ca. 1.5 mm long; stigma branches erect, slender, 2.5–3.5 mm long, slightly shorter or equalling stamens, closely cohering, extended into 3 prominently outspread or down-turned, adaxially grooved lobes from branch clefts, branch tips somewhat capitate distally, basal lobes and distal apices papillose, otherwise smooth, yellow. Capsules obconical, 2.5–5.0 × 2.0– 2.5 mm, dehiscence circumscissile. Seeds depressed ovoid, 0.51 × 0.49 mm, blackish brown, densely colliculate. Flowering period: February–May.  
 Distribution and habitat:—The Eastern Cape Pauridia trifurcillata is one of the few species of Pauridia endemic to the province. Populations are known from the Bosberg near Somerset East in the north through to Bedford in the east and southwestwards to the lowlands stretching from Humansdorp to near Peddie (Fig. 13). Found within grassland the species’ habitat includes moss-covered rocks on mountain slopes, shaded river banks, seasonally wet drainage lines, and the edges of vleis.   
 Diagnostic features:—This species is easily distinguished by the flower’s unique stigma branches, which are mostly erect, slender and closely cohering. Furthermore, these are stigmatic only at the capitate apex and on the basal extensions from each branch cleft. Elsewhere the branches are smooth. The three basal, papillose lobes, which are grooved adaxially, are prominently outspread to down-turned, giving the style its distinctive threepronged, fork-like appearance.   
 The species is similar to Pauridia maryae with regard to the soft leaves and smooth, brown, papery basal sheath. Thus in the past, herbarium collections of the two taxa have often been confused with each other. P. maryae flowers later in the year, from late winter until early summer (July to November), and although the stigma branches are narrow like those of P. trifurcillata, these are papillose over their entire length.
