A small somewhat shrubby herb, the average height of 
the specimens measured being 5 centimetres. The stems 
are stiff and narrow and rather sparsely covered with short 
stiff hairs. The majority of the branches rise from the base 
of the plant. The leaves are glandular alternate and pinna- 
tipartite, length without the petiole about 1 cm., the basal 
ones provided with a fairly long petiole, those springing 
from higher up on the stem are almost sessile. The peduncle 
usually bears a small single faleate bract some distance 
below the head. The receptacle is only slightly convex; 
the involucre is almost hemispherical, the bracts being 
situated in 3 to 4rows. Those of the outer row measure 
about “4 cm., and are densely covered with rough brown 
glands like those of the peduncle. The inner bracts measure 
about ‘7 cm., and are membranous, glabrous, and lanceolar. 
The inner bracts project out about as far as the bristles of 
the pappus, and are slightly coloured at the tips. There 
were no young flowers in the specimens examined. The 
achenes are slightly bean-shaped and glabrous, being about 
1°5 mm. in length, and ‘5mm. in breadth. The base of the 
achene is blunt. The beak of the achene is hair-like, 2°5 mm. 
long, and slightly swollen where the bristles of the pappus 
arise. There are usually 15 bristles in each pappus, each 
bristle being 3 mm. long and white, with pointed teeth.

is marked by Tate as either a variety of P. cuneifolia, or 
a new species.
