Characteristics

Plants 0.1-0.3 m tall, of varied appearance. Bulb globose, 15-30 mm in diam., with brown outer tunics. Leaves (2)3(5); in the S.W. Cape forming a basal spreading rosette during the winter months; leaf-bases forming a short neck, never fibrous, brittle and thin when dry; lamina narrowly ovate to linear-acuminate 80-250 mm long, glabrous or striate-puberulous and/or with long fine hairs, often with a purplish tinge at the base: margin entire or crisped; in the summer rainfall region the leaves envelop the peduncle, and are usually longer and erect, softly pubescent to glabrous. Raceme usually subspicate, the many flowers close together, elongating with age, terminating usually with some small sterile flowers; in weaker plants flowers few, more widely spaced; peduncle terete, straight, or with a spiral basal twist in some plants found in the eastern Cape: bracts small, deltoid-acuminate, auriculate, denticulate, membranous; pedicels 1-6 mm, erect. Flowers; a few open at a time during the day. Perianth-segments linear, acute, 5-10 mm long, white or pale dull yellow or pale pink, with or without a dark dorsal keel, delicate and thin in texture to more fleshy. Stamens with the outer filaments linear, inner ovate-acuminate. Ovary obovoid; ovules biseriate with c. 8 in each locule, or 3-4 seriate, with many; style terete, about as long as ovary; stigma apical. Capsule ovoid, c. 9 mm; seed somewhat cuneate, angled through pressure, 1.5-2 mm, with a loose testa.
