Characteristics

Plants several-to many-stemmed. Leaves erect to arcuate-spreading, dull green to glaucous, 350-800 x 6-18 mm, keeled, V-shaped in cross section, usually tough and often drying with a hard, fibrous texture; margin and keel smooth to sparsely serrulate towards apex. Scape overtopping or subequal to leaves, up to 1 m tall. Raceme oblong to globose, dense to sub-dense, sometimes lax at apex, 45-110 x 50-80 mm; buds spreading, brilliant scarlet to greenish tinged with red; flowers eventually pendulous, orange-yellow to greenish yellow. Bracts broadly ovate to oblong-ovate, rounded or obtuse to subacute, 3-9 mm long; margin almost entire to eroso-denticulate. Pedicels (1.5-)3.0-5.0 mm long, elongating to 3-8 mm long in the fruiting stage. Perianth subcylindrical, 28-40 mm long; lobes ovate, 2 mm long, slightly spreading. Stamens included or just exserted at anthesis, finally exserted by 3-5 mm. Fruit ovoid-triquetrous, 7-14 mm long. Flowering time: in Eastern Cape in autumn from January to May, but in Western Cape it may occur at almost any time from September to June, depending largely on veld fires, with two peaks, namely, October-December, and April-May.
