In seasonally burnt grassland and dry bush country; 900–1600 m.

General Description

A terrestrial herb 22–60 cm. tall. Perennating organs underground, tuberous, obliquely irregular conical, in chains, 1.5–3.3 cm. long, 2.2–2.6 cm. diameter, yellow; roots 3–4 mm. in diameter. Leaves 7, not plicate, linear, acute, 10–30 cm. long, 8–12 mm. wide, lowest 3 sheathing. Inflorescence produced before leaves, laxly many-flowered; peduncle 2–3 mm. diameter, bearing 2–3 sheaths along length; rhachis 7.5–30 cm. long; bracts linear, acuminate, 4–8 mm. long. Flowers very small, yellow or greenish yellow spotted or marked with purple or brown; pedicel and ovary 15–17 mm. long. Dorsal sepal spreading, oblong-elliptic, obtuse, 4–6 mm. long, 2.2–2.5 mm. wide; lateral sepals similar. Petals subcircular to broadly ovate or elliptic, obtuse, 5–5.5 mm. long, 3.3–4.8 mm. wide. Lip 3-lobed, 5–5.8 mm. long, 6–6.2 mm. wide; side lobes elliptic, acute, fused in basal half to column; mid-lobe convex, circular, rounded or obtuse, 3–4 mm. long; callus of 3–5 fleshy rugulose ridges; spur conical, 1 mm. long. Column 1.5 mm. long. Fruit pendent, 16–21 mm. long. Fig. 109/10–18, p. 478.

Very slender terrestrial herb 20–60 cm tall.Perennating organs subterranean, tuberous, 1.5–3.5 × 2.2–2.6 cm, irregularly conical, forming chains.Leaves c. 7, 10–30 × 0.8–1.3 mm, linear, acute, not plicate, absent at flowering time.Inflorescence rather laxly many-flowered; capsules starting to develop before the flowers fade.Pedicel and ovary 12–15 mm long; bracts 5–7 mm long.Flowers very small, yellow-green streaked with purple or chocolate-brown with a yellow lip.Sepals 4–5 × 2.2–3 mm, oblong-elliptic, obtuse.Petals 4–5 × 3.5–5 mm, broadly ovate to suborbicular.Lip 5–6 × 4–5 mm, 3-lobed; side lobes erect, joined at base to column; mid-lobe 3–4 × 3–3.8 mm, convex, suborbicular, obtuse; spur conical, very short, c. 1 mm long.Column 2–2.5 mm long.Fruit 15–20 mm long, purple, pendent.
