Leaves very closely imbricated, erecto-patent, $-§ in. long, obovate-spathu- 
late or rhomboid-spathulate, obtuse or subacute, upper 4 triangular, 
coriaceous, clothed on both surfaces with densely felted woolly hairs, which, 
as in R. bryoides, do not conceal the shape of the leaf; basal 3 mem- 
branous, 3-nerved when the tomentum is removed, upper suriace glabrate 
or nearly so, lower surface slightly silky ; margins furnished right to the 
base with long cottony hairs. Heads Zin. diam., solitary, terminal, 
sunk amongst the uppermost leaves; involucral bracts in 3-4 series, 
linear-oblong, scarious, acute, much smaller in proportion to the size of 
the head than in R, bryoides, and the inner ones with much less conspicuous 
white tips. Florets 20-40, the hermaphrodite about equal in number to 
the females. Achenes with long silky hairs and a conspicuous thickened 
areole. Pappus-hairs few, fragile, thickened at the tips.

Although this is technically closely allied to R. bryoides, in appearance it differs 
widely from that plant. &. bryoides forms hard and compact knobby masses in 
which the numerous branches are so closely packed that it is impossible to thrust the 
finger in between. &. Gibbsit is comparatively laxly branched, with longer, stouter, 
and more erect branches, and the leaves are much larger. The heads are also larger, 
with double the number of florets, and the scales of the involucre are proportionately 
smaller and less numerous, 
Mr. Gibbs, who is the first to gather this interesting species, informs me that at 
a little distance it can be easily mistaken for a barren specimen of Leucogenes grandiceps.

In the first edition of this work (p. 339) I remarked that “this differs from 
Helichrysum in habit and in the numerous female florets, and would perhaps be more 
appropriately placed in Raoulia, of which it has the pappus-hairs of the section 
Imbricaria.” In 1912 Beauverd adopted the suggestion thus made. It is a beautiful 
little snow-white plant, often forming large patches in alpine districts.
