5. A. Buchanani, Hook. f. Handb. N.Z. Fl. 57.—Stems and 
branches numerous, prostrate, closely appressed to the ground; 
young ones more or less villous with silky hairs. Leaves 4-1 in. 
long, hoary or silky, sometimes densely so; leaflets 3-6 pairs, 
broadly oblong-ovate or rounded, deeply minutely toothed. Heads 
small, 3-10-flowered, sessile. Calyx-tube broadly turbinate, 
4-angled, densely villous; lobes 4, persistent. Stamens 2. Stigma 
fimbriate. Fruiting-calyx short and broad, 4-angled and ridged, 
pilose; bristles 4, stout, spreading, yellow, usually hairy above or 
barbed. Achenes 1 or 2, bony.—Kirk, Students’ Fl. 134.

of the Clutha Valley, Petrie ! 
This can be recognised by the small size, pale-greyish colour, villous leaves 
and branches, small sessile heads, and yellow bristles. 
6. A. glabra, Buch. in Trans. N.Z. Inst. iv. (1872) 226, t. 14. 
—Lverywhere perfectly glabrous. Stems much branched, prostrate, 
stout and woody at the base; branches erect or ascending, leafy. 
Leaves #-14in. long; leaflets 3-4 pairs, 1-4in. long, obovate or 
oblong-obovate, cuneate at the base, deeply and coarsely toothed. 
Peduncles 2—5in. long, stout; heads globose, }-#in. diam., often 
unisexual. Calyx-tube much compressed, the lateral angles pro- 
duced into a broad wing-like process on each side ; lobes 4, broad, 
persistent. Male flowers with 20-40 stamens; females with 1 or 2 
stigma fimbriate. Fruiting-calyx always unarmed, red. Achene 
narrow, tapering to both ends.—Kirk, Students’ Fl. 134.

A very ilistinet species, easily recognised by the perfectly glabrous habit and 
large unarmed heads. It differs from all the other species of the genus in the 
numerous stamens of the male flowers. 
Orper XXIV. SAXIFRAGEA. 
Trees, shrubs, or herbs. Leaves alternate or opposite, simple 
or compound, stipulate or exstipulate. Flowers usually regular and 
hermaphrodite. Calyx free or adnate to the ovary, lobes 4-5, 
imbricate or valvate. Petals 4-5, rarely wanting, imbricate or 
valvate. Stamens as many or twice as many as the petals, rarely 
more, perigynous or epigynous, very rarely hypogynous. Disc 
usually present between the stamens and the ovary, very various 
in shape. Ovary free or more or less adnate to the calyx-tube, 
usually 2—5-celled with 2-5 axile or parietal placentas; styles as 
many as the cells, free or more or less united; ovules numerous, 
anatropous, erect or pendulous. Fruit usually capsular, more rarely 
succulent and indehiscent. Seeds usually small, numerous; albu-
