A very variable plant, especially in the size and shape of the leaves, and 
the extent to which they are clothed with white tomentum. Mr. Colenso 
describes his R. albosericea as having few florets and few pappus-hairs; but the 
specimens in his herbarium are long past flowering, and have evidently lost 
most of the florets and much of the pappus, and apparently do not differ from 
the type in any essential character. 
9. R. tenuicaulis, Hook. f. Fl. Nov. Zel. i. 135, t. 36a.—- 
Stems slender, prostrate and creeping, much and laxly branched, 
1-10in. long; branches ascending at me tips. Leaves laxly 
imbricating, spreading or recurved, 7-74 in. long, linear-oblong 
or lanceolate-spathulate, or on luxuriant shoots obovate-spathu- 
late, acuminate or apiculate, concave, more or less clothed with 
greyish appressed tomentum or almost glabrous. Heads 3-1 in. 
long; involucral bracts in 3 series; outer tomentose or glabrate, 
acute; inner scarious, with brown acute or obtuse tips. Florets 
from 10 to 16, the females about equalling the hermaphro- 
dite ones in number. Achene glabrate or puberulous. Pappus- 
hairs copious, very slender.—Handb. N.Z. Fl. 148; Kirk, Bee
