12. R. Petriensis, 7. Kirk in Trans. N.Z. Inst. ix. (1877) 549. 
—Usually forming Jaxly branched patches. Stems 2-6 in. long, © 
prostrate or suberect; branches numerous, ascending or erect, 
viscid, with the leaves 4-1in. diam. Leaves laxly imbricating, 
1-1in. long, obovate-spathulate ; base erect, membranous, loosely 
cottony ; tip spreading or recurved, rounded, coriaceous, clothed 
with densely felted shining tomentum. Heads iin. diam., sessile 
among the terminal leaves; involucral bracts in 2 series, linear, 
scarious, obtuse, the inner with short white radiating tips. Florets 
30-50 ; female very slender, filiform, 8-15. Achene glabrous or 
puberulous. Pappus-hairs thickened at the tips. — Students’ Fl.

Soutu Isnanp: Canterbury — Mount Dobson Range, 7. F. C. Otago— 
Mount Ida and Mount St. Bathans, Petrie ! 3500-5500 ft. December-— 
January. 
A remarkably distinct species, at once recognised by the loosely tufted habit, 
long slender branches, spreading and recurved leaves, and numerous florets. 
13. R. mammillaris, Hook. f. Handb. N.Z. Fl. 150.—Forming 
hard compact masses similar in size and aspect to those of Ff. exi- 
mia. Branches short, stout, with the leaves quite +in. diam. 
Leaves most densely Baase imbricated all round the branches in 
many series, spreading, ;4—4in. long, obovate-cuneate or spathu- 
late, rounded or almost truncate at the tip, membranous, glabrous 
or nearly so in the lower half, in the upper half clothed on both 
surfaces with a dense tuft of straight hairs which project just 
beyond the tip and conceal the leaf. Heads 1—+in. diam., sunk 
among the leaves at the tips of the branches; involucral bracts in 
about 2 series, the inner linear-oblong, scarious, with conspicuous 
white obtuse or subacute radiating tips. Florets 10-12, the her- 
maphrodite ones more numerous than the females. Achene clothed 
with long silky hairs, and with a thickened areole at the base. 
Pappus-hairs few, rigid, thickened at the tips.—Kirk, Students’ FI.

SourH Isnanp: Nelson—Mount Starveall, Bryant (‘‘ Students’ Flora ’’). 
Canterbury—Mount Torlesse, Haast (Handbook). Otago—Alps of the Lake dis- 
trict, Buchanan! 4000-6000 ft. Vegetable sheep. 
The conspicuous white radiating tips to the inner involucral bracts distin- 
guish this at a glance from &#. exinvia, but in the absence of flowers it is by no 
means easy to separate the two species The leaves of R. mammillaris, how- 
ever, are shorter and broader, with shorter hairs which do not project so far 
beyond the tip of the leaf asin R. eximia. The only specimens I have seen are 
Mr. Buchanan’s, which are in full flower, and unmistakable. The Mount Starve- 
all locality is given on the authority of Mr. Kirk, but there are no specimens 
from thence in his herbarium. 
14. R. rubra, Buch. m Trans. N.Z, inst. xiv. (1882) 350, t. 30, 
f. 2.—Forming hard compact masses 6-12in. diam. and 4—8in. 
high; branches with the leaves 34-4in. diam. Leaves closely
