Habit

Deciduous geophyte 90-160 mm tall when in flower, tuber turnip-shaped, sometimes with more than one growing point.



Leaves
Lamina tripalmate with three main pinnae, petiolule 70-150 mm, 3-5 pinnulae of the first order, 15-20 x 15-20 mm, 3-5 pinnulae of the second order, palmatifid, apices of segments acute, adaxially and abaxially hirsute with appressed stiff hairs. Petiole 140-170(-280)mm long and 1-2 mm in diameter, reddish brown, rigid, spreading horizontally from the growing point but bending upright, stipules subulate, 25-30 mm x 1-2 mm, adnate to petioles for 2/3 of their length.

Inflorescence
Scape 20-60 mm, reddish brown, densely hirsute with appressed hairs interspersed with short glandular hairs, branched, bearing 2-5 pseudo-umbellets with 4-13(-17) flowers each, peduncles 25-60 mm long, reddish brown, covered with short glandular hairs sparsely interspersed distally appressed hairs, proximally reddish brown, distally pink to pale green, bracts lanceolate, 1-3 mm long. Pedicel cca. 0.5 mm.


Sepals
5, lanceolate, apices acute, 5-7 x 1-2 mm, patent, abaxially covered with glandular hairs and appressed stiff hairs, with white margins. Hypanthium 10-17 mm, 2-3 times as long as the sepals, pale green, sparsely glandular.

Petals
5, pale yellow, patent during anthesis; posterior two with minute white-red feather-like markings, spathulate, claws 4-6.5 mm long, apices truncate or emarginate, 13-16 x 3.5-5.5 mm, length/width ratio smaller than 4; anterior three spathulate, bases attenuate, apices rounded, 11-14 x 2.2-4 mm.


Stamens
5 fertile, posterior one 5-7 mm, lateral two 6-8.5 mm, anterior two 7.5-10 mm, protruding from the flower, white; anthers pale pink, pollen yellow. 

Distribution


Habitat

The central Richtersveld is a place of magic. The gently rolling landscape bursts into various shades of green after autumn and winter showers. Following a few years' drought, some shrubs may not recover, but others leaf up and new opportunities arise for the undergrowth. P. tripalmatum, flowering in November, is essentially found within such older shrubs, sheltered from sheep and other grazing animals that have destroyed so much vegetation in this sensitive habitat.
