Plants (150-) 200-500 mm high. Corms moderately or very deep-seated, 15-30 mm diam., tunics of coarsely netted, woody fibres, sometimes connate below into flat claws, extending shortly into a fibrous neck to 20 mm long, chestnut brown. Basal leaves 4-6, suberect, lanceolate, 80-200 x 10-20 (-25) mm, acute to attenuate, plane or canaliculate, with prominent midrib and ribbed veins abaxially, soft-textured, glabrous, margins smooth or ciliolate-scabridulous. Inflorescence a dense or moderately dense raceme up to 35-flowered, with 1-4 branches, lower flowers 0.2-0.5 times pedicel length apart; pedicels suberect, deflexed at bracteole, mostly 15-30 mm long; bracteoles mostly inserted in upper third or quarter. Flowers facing outwards, pink with paler centre variously speckled with dark pink, the whole outlined with darker shading, fragrant; tepals spreading, outer elliptic, 8-10 x 4-5 mm, apiculate, inner obovate, 8-10 x 5-6, narrowed and shortly clawed below. Stamens dimorphic, 3 + 3; filaments of posterior cluster geniculate-sigmoid, 2-5 mm long, distally filiform, swollen basally, connate at extreme base only, yellow with white base, anthers ± sagittate, 1.5-2.0 mm long; filaments of anterior cluster deflexed, 1.0-1.5 mm long, connate at extreme base, anthers 2.5-3.0 mm long, pale yellow but greyish in distal half or third. Ovary half inferior, style medially deflexed, 3-4 mm long, not extending beyond anthers. Capsules erect, ovoid-ellipsoid, (12-) 15-20 x 8-10 mm. Seeds ovoid-ellipsoid, 3-4 x 1.5-2.0 mm, glossy black, rugose.
