Characteristics

A terrestrial herb 1–6.5 dm. high, glabrous except for the roots.. Tubers ellipsoid, ovoid or fusiform-ovoid, 1–3.5 cm. long, 4–13 mm. in diameter,± tomentose.. Roots slender, flexuous, pubescent.. Sterile stem usually very short, up to 6 cm. long, 2–5-leaved; lowest 1–3 leaves sheath-like, subacute or obtuse, the upper 1 or 2 lanceolate to ovate-elliptical, acute or obtuse, up to 3.5–22 cm. long and 1–9 cm. broad.. Fertile stem slender to rather stout, covered by sheathing leaves; sheaths 3–9, lanceolate, acute, up to 2.5–10 cm. long and 1–3 cm. broad, decreasing in size upwards.. Inflorescence cylindrical, up to 23 cm. long, 2.5–4 cm. in diameter, rather loosely to densely 1-to many-flowered; bracts soon reflexed, lanceolate, acute, 1–3.5 cm. long, the lower ones often longer than the flowers.. Flowers curved outwards, white or variously suffused or tinged pink, fragrant; pedicel with ovary curved, ± 1 cm. long.. Sepals and petals deflexed, united to one another and to the lip in their basal fourth.. Intermediate sepal oblong-elliptical, obtuse, 9–13 mm. long, 2–3 mm. broad; laterals obliquely elliptical-oblong, obtuse, a little longer and broader than the intermediate.. Petals similar to the intermediate sepal but a little shorter and broader, ciliolate in the apical part; all tepals 3-veined.. Lip very convex and hooded with the apex shortly recurved, 8.5–12 mm. long and ± the same in breadth when spread out, the mouth broad.. Spurs ± parallel to the ovary, narrowly cylindrical, 2.5–4.5 cm. long.. Column erect, 6.5–9 mm. high, the stalk slightly longer than the fertile part; anther-loculi pendent, ellipsoid; stigma erect, orbicular to transversely elliptical, 2–3 mm. tall, 2.5–4 mm. broad, rostellum porrect, 2–3 mm. long, 3-lobed, the side lobes short, triangular, the middle lobe much longer, ± orbicular from a narrower base.

Plants (170-) 260-530 (-810) mm tall; leaves 1 or 2, on a separate shoot next to the flowering stem, 40-200 mm long. Inflorescences lax, (3-) 12-35 (-60)-flowered; bracts narrowly ovate, 1.4-1.8 times the length of the 6-15 mm long ovary, strongly deflexed. Flowers white to pink, usually with deeper-coloured nerves, spurs and distal parts of sepals and petals tinged deep pink. Sepals free almost to the base and distally fairly sharply recurved. Petals forming with the sides of the lip a loose tube, then sharply deflexed. Lip with prominent puberulous apical flap; spurs 15-46 mm long. Viscidia elliptic and prominent; stigma very broadly obovate, emarginate, c. 2 mm tall; rostellum slightly longer than stigma, with appendix.
Plants terrestrial, robust, 0.17-0.81 m high. Leaves 1 or 2, radical, on sterile shoot, ovate-elliptic, spreading, 40-200 x 60-75 mm. Inflorescence lax, 12-60-flowered; bracts deflexed. Flowers white to pink, floral parts tinged pink, darker veins, petals dry to brown shortly after anthesis. Sepals free. Petals forming tube with sides of lip, sharply deflexed. Lip with prominent apical flap; spur 15-46 mm long. Flowering time Dec.-Feb.
Stout, tuberous geophyte to 80 cm. Leaves 1 or 2, ovate, on a separate shoot next to flowering stem, bracts deflexed. Flowers many in a lax raceme, white to pink and usually partly with pink tinge, spurs filiform, 15-46 mm long.
A slender herb. It is an orchid that grows in the soil. It grows 10-65 cm high. The leaves are on a separate sterile shoot. The leaves along the flowering stem sheath. The flowers are white. The tubers are 1-4 cm long and oval.
Column 6.5–9 mm high; stigma 2–3 × 2.5–4 mm; rostellum 2–3 mm long, the mid-lobe ± orbicular from a narrow base, much longer than side lobes.
