Description

''Hemiphora uncinata'' is an erect, spreading shrub which grows to a height of with its branches covered with white, cottony hairs. The leaves are linear to lance-shaped, long, wide, with their edges curved downwards or under and often have a hooked tip. The upper surface is rough and wrinkled with small blisters and the lower surface is covered with woolly hairs at least when young. The flowers are deep pink and are arranged singly or in groups of up to three on woolly stalks long, in upper leaf

s are long, and joined at their base to form a short tube. The sepals are woolly on the outside, linear to lance-shaped and remain attached to the plant after the petals have fallen.
