= Ianthe cuspidata Nel (1914b: 294) ≡ Spiloxene cuspidata (Nel) Garside (1936: 268) ≡ Hypoxis cuspidata (Nel) Geerinck (1969: 78) . Type (holotype):— SOUTH AFRICA, [Western Cape], Brakfontein [QDS: 3218BD], Ecklon & Zeyher [Hypoxid 19] (B! No. 100089225 [image], isotype W)

Plants 2.5–23(–30) cm tall. Leaves 2–10, sheathing up to 30 mm, suberect to slightly arched, rarely outspread, linear to lanceolate, 30–175 × 1–27 mm, tapering evenly upwards, or rarely abruptly expanded above neck, canaliculate proximally to carinate distally, midrib prominent abaxially, firm- or rarely thin-textured, margin sometimes minutely papillate. Flower yellow, backed with pale green in outer whorl, sometimes reddish brown towards tips, contrasting colouring less marked in inner whorl; pedicel suberect at anthesis, deflexing somewhat laterally in fruit, terete, 15–112 × 1 mm; tepals oblong-lanceolate to elliptical, 5–16(–19) mm long, outer 2.0– 5.5 mm wide, inner 1.7–5.0 mm wide. Stamens suberect, rarely subequal, outer whorl shorter than inner, yellow; filaments shorter than anthers, outer 1.0–2.0 mm long, inner 1.5–2.5 mm long; anthers 2.5–6.5 × 1.0– 1.5 mm; pollen yellow. Ovary narrowly obconical, 2.0–5.0 × 1.3–2.5 mm; style 0.3–2.5 mm long; stigma branches erect, 2.5–6.0 × 0.7–1.7 mm, ca. shorter than to equalling stamens, yellow. Capsule narrowly to broadly obconical, 3–14 × 2–6 mm. Seeds depressed ovoid, 0.45–0.62 × 0.37–0.54 mm; testa dark brown, of ca. 21 widely separated rows of hump-like projections, outline of anticlinal walls not evident. Flowering period: (June–)July–September(–November at high altitudes).

Distribution and habitat:— Pauridia gracilipes subsp. gracilipes is found in Northern Cape and Western Cape Provinces, extending from the Kamiesberg in Namaqualand southwards to the outskirts of Cape Town ( Fig. 33B ). Over this range plants are found in localized populations in soils derived from decomposed granite and sandstone, usually along the edges of seasonal streams and seepage areas, and often partially shaded by rocks.

Diagnostic features:—Unless dwarfed by growing in shallow soils, like those matching the type of Spiloxene cuspidata , most plants of subsp. gracilipes are erect with distally arching and usually firm leaves. This subspecies, however, also includes several broad-leaved plants, with thin-textured leaves, typically found in wet rock crevices and shaded rock banks. It is distinguished from subsp. speciosa by its generally smaller flowers which are invariably yellow.
