Acaena. | ROSACEAE, 509 
Leaves 1$-3in. long; stipules lanceolate, erect, 2-3-fid; petiole and 
rhachis usually more or less pilose, sometimes densely so; leaflets 11 to 13 
(5 to 6 pairs with a terminal one), the lowest pair minute; uppermost 
pair the largest, 4-2 in. long, oblong or elliptical, coarsely serrate-dentate ; 
the leaflets as a rule green or brownish-green above, more or less glaucous 
beneath; upper surface nearly glabrous, under-surface with appressed 
silky hairs on the veins and margins. Scapes terminating the branches, 
2-6 in. long, rarely more, stout, erect, often purplish-red. Heads globose, 
large, 2-1} in. diam., purplish-red. Sepals 4, densely pilose; spines 4, 
barbs usually paler than the spines. Stamens 2; anthers reniform, as_ 
broad as long. Stigma bilaterally plumose—Stwdents’ Fl. (1899) 133;

Wellington, 7. Kirk / 
Bitter, in his monograph of the genus, reduces Kirk’s A. novae-zelandiae to the 
rank of a subspecies of A. sanguisorbae, thus associating it with his subspecies 
caestiglauca, profundeincisa, and pusilla, together with various Australian plants. 
But I have always regarded A. novae-zelandiae as fully entitled to the rank of a 
species; and, so far as the other subspecies mentioned above are concerned, I am 
in agreement with Cockayne, who says that it is simpler to treat A. novae-zelandiae 
as “an aggregate species, and to reduce all Bitter’s other New Zealand endemic 
subspecies to the rank of varieties.”’
