17. R. bryoides, Hook. f. Fl. Nov. Zel. ii. 332.—Forming hard 
and dense convex patches 2-8in. diam. Lower portion of the 
stem hard and woody, roots long and stringy. Branches short, 
stout, with the leaves 4-1in. diam. Leaves very closely packed, 
imbricated in several series all round the branch, erecto-patent, 
qo-4 in. long, narrow obovate-spathulate or rhomboid-spathulate, 
subacute or obtuse; lower two-thirds glabrous or slightly 
woolly, upper one-third about triangular, coriaceous, clothed 
on both surfaces with closely felted silky hairs which do not 
conceal the shape of the leaf, and with a tuft of cottony wool 
on each side. Heads 4-41in. diam., sunk among the terminal 
leaves; involucral bracts in 2-3 series, linear-oblong, scarious, 
acute, inner with white radiating tips. Florets 8-14, the her- 
maphrodite ones more numerous than the females. Achene with 
long silky hairs and a thickened areole at the base. Pappus-hairs 
few, rigid, thickened at the tips—Handb. N.Z. Fl. 150; Kirk, 
Students’ Fl. 307.

3500-6500 ft. December—January. 
Easily distinguished from R. eximia, ER. mammillaris, &c., by the hairs 
on the leaves not enveloping them so as to conceal their shape. 
11. HELICHRYSUM, Vaill. 
Herbs or small shrubs, very variable in habit, often woolly or 
tomentose. Leaves alternate or the lower rarely opposite, quite 
entire. Heads solitary or corymbose, heterogamous and discoid or 
homogamous through the suppression of the female florets. Invo- 
luere from cylindrical to broadly hemispherical; bracts in several 
series, with or without white or colourea spreading petal-like sca- 
rious tips. Receptacle flat or convex, naked or pitted. Female 
florets exterior, few, sometimes altogether wanting, filiform, mi- 
nutely 2-3-toothed. Disc-florets hermaphrodite, numerous, tubular 
with a funnel-shaped 5-toothed mouth. Anthers sagittate at the 
base, produced into fine tails. Style-branches of the disc-florets 
almost terete, truncate or subcapitate. Achenes small, terete, 
5-angled or compressed. Pappus-hairs in one series (rarely in 
several series), free or connate below, simple or barbellate or plu- 
mose above. 
A very large and heteromorphous genus, found in most parts of the world, 
and especially plentiful in South Africa and Australia. It has been united with 
Gnaphalium by many authors, but can usually be distinguished by the her- 
maphrodite florets being always much more numerous than the female ones. 
All the New Zealand species are endemic.
