Disa nervosa Lindl.

Plants robust, 400-800 mm tall; basal sheaths 2-3, dark brown, up to 100 mm long; leaves falcate to erect, imbricate, conduplicate, narrowly lanceolate, up to 250 mm long, grading into the floral bracts. Inflorescences dense, 80-250 mm long; bracts usually as long as the ovaries. Flowers inserted at 45-90° to the scape, facing out horizontally, pink with purple markings or spots at the petal apices. Median sepal angled forwards, narrowly oblong, shallowly galeate, 15-25 mm long; spur horizontal basally, decurved at length, usually filiform, tapering, acute, 12-20 mm long; lateral sepals oblique, lorate to narrowly lanceolate, shallowly navicular, often facing inwards, 15-25 mm long, with fleshy acute apices. Petals erect next to the stigma, lorate, emarginate, apical part often reflexed out of the galea, 13-23 mm long. Lip patent, linear, often somewhat widened apically, acute, 17-28 mm long. Anther semipen-dent; stigma subequally tripulvinate, margins taller than and curved over the receptive surface; central rostellum lobe finger-like, curved forwards, taller than the lateral lobes.
