). It has shallowly cup-shaped perianth tubes and narrowly spreading tepals. The outer tepals have a prominent deep pink median keel and apical gibbosity, and the strongly protruding inner tepals have a dull pink median keel. The flowers have bracts that are ovate at the base of the inflorescence and lanceolate above, and well exserted, narrowly spreading, white stamens. The inflorescence emerges towards the end of the growing season, as the leaves start to wither. The species is further recognised by two linear, suberect or recurved, deeply canaliculate, conduplicate leaves, with acute apices. The upper and lower surfaces are light green, and the lower surfaces are heavily magenta- or purple-barred in the lower third, and green-barred in the upper two thirds. The primary seedling leaf is terete, with erect orientation. The fruit is an obovoid capsule containing globose, matt black seeds with rugose primary sculpturing, and ridged strophioles.
