tuft of straight white hairs slightly longer than the leaf, the extreme upper 
margin naked although concealed by the hairs. Heads small, deeply 
sunk among the leaves at the tips of the branches; involucral bracts in 
2 series ; the outer linear-spathulate, scarious, bearing a tuft of hairs at the 
tip; the inner linear, scarious, obtuse, some of them with short hardly 
radiating white tips. Florets few. Achene hispid, with a thickened 
areole. Pappus-hairs few, thickened upwards.—Students’ Fl. (1899) 306 ;

hard compact masses. Branches short, stout, with the leaves on din. 
diam. Leaves closely packed, imbricated in several series, 3-$1n. long 
and almost as broad at the tip, broadly cuneate, truncate, membranous ; 
upper surface with the lower 2 quite glabrous, above that clothed with 
straight hairs which project just beyond the tip, forming a kind of 
fringe; under-surface with the lower 4 loosely silky, the upper } glabrous, 
more or less corrugated or wrinkled. Heads small, hidden among the leaves 
at the tips of the branches. Involucral bracts in 2 series, lanceolate, 
concave, acute, glabrous within ; without ciliate at the base, glabrate at 
the apex. Florets few, short; pappus-hairs and styles of equal length.

The manner in which the hairs are placed on the leaves is well worth examination. 
On the upper surface they are confined to the upper $ of the leaf, forming a straight 
dense fringe just reaching above the level of the truncate tip of the leaf, the lower part 
of the leaf being quite glabrous and wrinkled when dry. The back, or under-surface, 
of the leaf is furnished with a lax tuft of long silky hairs springing from the base of the 
leaf ; but above that the leaf is quite glabrous.
