Middle bracts (2.5-)3-4(-4.5) × (1.5-)1.7-2.5(-3) cm., rounded, dark brown or sometimes purplish, covered with silver or grey-brown appressed hairs or glabrescent in parts towards margins or (particularly var. angolensis) sometimes glabrescent throughout; inner bracts (6-)7-9 × (0.4-)0.7-1.2(-1.5) cm., ± equalling the flowers, otherwise like middle bracts.. Flowers (5-)5.5-6.5(-7) cm., creamy white to bright pink.. Perianth-base glabrous outside, with dense hairs near the margin of the upper part inside; claw glabrous or (var. angolensis) with long whitish hairs inside and occasionally outside; limb (18-)20-25(-30) mm., villous on the 3 fused segments, glabrous to pubescent or occasionally villous on the fourth segment..
