Habit

Deciduous geophyte 130-170 mm tall when in flower, tuber turnip-shaped, sometimes with more than one growing point.



Leaves
Lamina of juvenile leaves simple, later leaves pinnatisect, bright green, elliptic in outline, 40-60 mm long, pinnae obovate, 7-20 x 5-15 mm, apices obtuse, margins entire, ciliate, adaxially glabrous and abaxially with appressed stiff hairs along main veins. Petiole 30-85 mm long and ca. 2 mm in diameter, prostrate, densely hirsute with appressed curly hairs, stipules subulate, 15-20 x 1-2 mm, adnate to petioles for 2/3 of their length.

Inflorescence
Scape (10-)30-50 mm long, reddish-green, densely hirsute with short appressed hairs, branched, bearing 3-6(-8) pseudo-umbellets with 3-7(-10) flowers each; peduncles 45-90(-160) mm long, densely hirsute with short appressed hairs interspersed with short glandular hairs. Pedicel cca. 0.5 mm.


Sepals
5, lanceolate, apices acute, 4.5-6 x 1-2.5 mm, posterior one erect, others reflexed, indumentum abaxially as on peduncle, green to reddish-green, margins white. Hypanthium 16-20(-25) mm, 3-4 times as long as the sepals, green to greenish brown, indumentum as on peduncle.

Petals
5, white, pale pink or salmon, patent during anthesis, posterior two with minute wine-red feather markings, ligulate, 14-15 x 1.5-2.5 mm, length/width ratio 6-10, claws 5-6 x 2 mm, apices rounded; anterior three spathulate, 10-12 x 1.6-2.5 mm, bases attenuate, apices rounded. 


Stamens
5 fertile, posterior one 2-2.5 mm, lateral two 3-4 mm, anterior two 4-5 mm, shorter than the sepals, white, anthers pink, pollen orange. 

Distribution


Habitat

The dolerite flats around Nieuwoudtville are extraordinarily rich with geophytes - no wonder the town calls itself the bulb capital of the world. P. glabriphyllum is found exclusively in seasonally wet dolerite flats that are almost impossible to navigate as the entire landscape turns into deep mud. However odd this habitat may be, it harbours one of the most localised and least known hoareas. P. glabriphyllum flowers from October to February.
