1. R. australis, Hook.f. FI. N. Z. i. 135. A small, moss-like, densely- 
tufted plant ; stems 1-2 in. high ; branches slender, erect or prostrate. Leaves 
minute, laxly or densely imbricate, T l 6 — yV in. long, spathulate, erect or recurved, 
rounded at the tip, covered with silky appressed wool. Heads A-— i. in. long ; 
outermost scales spathulate, inner linear, searious, shining, yellow or pale 
brown, not dark at tips, nor white and radiating; florets about 12, outer few. 
Pappus hairs excessively slender, subpilose, not thickened at the tips. Achene 
glabrous or puberulous. — Raoul, Choix, t. 15. 
Northern Island: Tougariro and Waikato, Bidwill ; and elsewhere, in lofty, rocky 
hills, Colenso. Middle Island : iMelson mountains, Bidwill ; rocky hills at Akaroa, Raoul, 
Lyall ; Clarence, Tarndale plain, and Wairau valleys, alt. 3500 ft., Travers ; Southern Alps, 
Haast ; Otago, Hector and, Buchanan. A very variable plant. 
2. R. tenuicaulis, Hook.f. FI. N. Z. i. 135. t. 3G A. Stems generally 
slender, loosely tufted, prostrate, creeping, 1-10 in. long, with ascending 
branches. Leaves loosely imbricating, spreading and recurved, A— in. long, 
linear-oblong or spathulate-lanceolate, apiculate or acuminate, rarely broadly 
spathulate, grey with appressed silvery tomentum, rarely glabrate. Heads 
as in R. australis, but involucral scales with brown acute tips. 
Northern Island : gravelly beds of rivers, Wairarapa, Ruanahanga, Palliser Bay, etc., 
Colenso. Middle Island: Kowai river, alt. 1-2000 ft., Haast. 
3. R. Haastii, Hook. f.,n. sp. A small, densely tufted, nearly glabrous 
species ; stems rather stout, prostrate ; branches 1 in. high. Leaves densely 
imbricate, erecto-patent, in. long, broadly sheathing, broadly ovate-subu- 
late, obtuse, coriaceous, obscurely woolly or silky. Heads as in R. aus- 
tralis, but narrower, with 6-8 florets ; involucral scales obtuse, not brown 
nor with a white radiating tip. 
Middle Island : gravelly terraces, Kowai river, Haast; Waiauna valley, alt. 3JJ00 ft., 
Sinclair, Travers. I was at first disposed to regard this as a form of R. tenuicaulis, but 
the leaves are very different in shape and in their broad bases, and the involucral scales are not 
brown at the tips. 
4. R. Munroi, Hook.f., n. sp. Stems slender, creeping, with very long, 
wiry, filiform rootlets. Branches slender, ascending, 1-2 in. high. Leaves 
laxly imbricate, patent and recurved, i f in. long, linear, obtuse, uniformly 
clothed with grey silky tomentum. Heads narrow, A. i n . long ; involucral
