Var. pilosa 7. Kirk Students’ Fl. (1899) 133.—Leaflets sreyish-glaucous on both 
sides with appressed silky hairs. Probably the same as Bitter’s subspecies caesiiglauca, 
of which I have seen no authenticated examples. It is an abundant plant in the 
mountains of the South Island. 
Var. profundeincisa Bitier Monog. Gatiung Acaena (1910).—Leaflets deeply incised, 
glaucous-green above, greyish-glaucous beneath. (Described from cultivated plants ; 
but a variety called sericenitens has been collected at Kelly’s Hill, Otira Valley, by 
Cockayne.) 
Var. pusilla Bitter Monog. Gattung Acaena (1910).—Smaller than the type. Leaves 
1-liin. long; leaflets 9-11, green above, often a little olive-brown, more or less 
pilose. Mature spines in. long, greenish-yellow suffused with red. NorTH AND 
SoutH Isranps : Not uncommon. 
Var. vitidior Cockayne in Trans. N.Z. Inst. xlviii (1916) 193.—Leaves green above, 
never a little olive-brown; calyx-lobes and spines pale-green. Of this Cockayne 
remarks (l.c.), “distinguished from the extremely common var. pusilla by its larger 
bright-green leaves, which have never brown basal leaflets, and the pale- but clear-green 
calyx-segments and spines, whereas the small basal leaflets of the var. pusilla are more 
or less deeply stained with brown, and the spines are pale and stained here and there 
with light-red.”” The following localities are known: Norra Istanp—Taranaki and 
near Wellington. Soutu Istann—Nelson Waterworks, <Banks Peninsula, near Kai- 
koura. 
Var. minor Hook. f. Fl. Antarct. i (1844) 9; Cockayne in Trans. N.Z. Inst. xlix 
(1917) 56; Cheesem. Vasc. Fl. Macquarie Is. (1919) 22.—Stem long, stout, creeping ; 
branches short, ascending, often rubescent. Leaves 14-3 in. long, pale-green above, 
beneath densely clothed with appressed silky hairs. Scape short and stout, 1-2) in. 
long. Head din. diam.; colour ranging from stramineous to pale rubescent.— 
A. sanguisorbae Vahl. var. antarctica Cockayne in Trans. N.Z. Inst. xxxvi (1904) 319; 
A. ganguisorbae Vahl. var, aucklandica Bitter Monog. Gattung Acaena (1910) 274. 
Nortu AND SoutsH Isuanps, STEWART IsLAND: The ordinary state of the species 
abundant from the North Cape to Stewart Island and Chatham Islands; var. minor 
confined to the AUCKLAND AND CAMPBELL IsLANDS, ANTIPODES ISLAND, AND Maco- 
QUARIE ISLAND. Sea-level to 3500 ft. Piripiri ; Burr. November-february. 
Bitter makes several changes of importance in the circumscription of 4. sanguisorbae 
which he divides into 3 separate species—({1) A restricted A. sanguisorbae, which includes 
all the varieties found in Australia, Tasmania, and New Zealand ; (2) A. insularis, literne, 
from New Amsterdam: and (3) 4. sarmentosa, from Tristan d’Acunha. The Australian 
forms are placed under 8 subspecies, all endemic. The New Zealand forms are also — 
considered to be distinct. I regret that from want of specimens I have been unable 
to deal with 3 varieties from Chatham Islands obtained by the German coliector 
Krull many years ago.

7. A. microphylla Hook. f. Fl. Nov. Zel. i (1853) 55—Stems stout, 
prostrate, much and widely branched, often forming extensive patches ; 
flowering branchlets short, erect, glabrous or nearly so. Leaves variable 
in size, 2-2in. long, sparingly pilose or almost glabrous; leaflets 7-13 
(3-6 pairs with a terminal leaflet), the lowermost pair minute; the 
following pairs gradually increasing in size, the uppermost pair or the 
terminal leaflet the largest, }-tin. long, broadly obovate or almost orbi- 
cular, membranous, crenate-dentate or serrate; colour variable, glauces- 
cent to olive-green or dark brownish-green. Heads globose, 4? in. diam. 
when mature, usually borne on scapes 4-3 in. long, rarely sessile. Calyx- 
tube (cupula) silky or glabrous, tetragonous, turbinate when mature, usually 
but not invariably furnished at the angles with 4 bright purplish-red spines 
devoid of barbs; achenes 2. Stamens 2; anthers 2, whitish or yellowish.
