Acaena. | ROSACEAE. 5O7T 
1. A. saceaticupula Bitter Monog. Gattung Acaena (1910) 173.—Stems 
creeping at the base, ascending above ; branches numerous, suberect, leaty 
below. Leaves small, 14-24 in. long, }in. broad; sheaths scarious, red- 
brown, glabrous, at the top passing into the frondose stipules; petiole 
short, glabrous, as also is the median rhachis and the whole of the lamina, 
with the exception of a few long hairs on the costa and near the axils of 
the leaflets. Leaflets 9-15, more or less glaucescent on. both surfaces, 
sometimes with a tinge of red; lower leaflet minute, usually 3-fid; upper 
the largest, 7-9-fid, glabrous throughout. Fruiting-scape 5-91in. long, 
usually somewhat rubescent, slender, erect. Flowers hermaphrodite. 
Sepals greenish suffused with purple, glabrous or with a few hairs. 
Stamens 2-4; anthers as long or broader than long, purplish. Cupule 
laxly saccate ; spines always 4 major ones, usually accompanied with 1-4 
of much smaller size. Stigma bilaterally plumose. 
~ Var. nana Bitter I.c.—Smaller in all its parts, but apparently not otherwise different. 
SourH Istanp: Probably not uncommon on the eastern side of the Southern Alps.

This is one of the plants referred to A. adscendens by Sir J. D. Hooker in the 
Handbook. But it differs from that species in its much smaller size, much more 
glabrous and more slender habit of growth, and in the leaves being glaucescent on 
both surfaces. “1 1GUH) Ke *, SU ( 16 1%) KS. 
2. A. adseendens Vahl. Enum. i (1804) 294. Stems stout, procumbent, 
12-20 in. long; branches ascending, glabrous, reddish-purple or rubescent. 
Leaves 24-4 in. long ; stipules large, 3 in. long or more, sheathing, purplish- 
red ; laminae 4-2 in. long, 6—7-foliolate, obovate or obovate-oblong, obtuse, 
deeply and coarsely serrate-dentate, firm in texture but not coriaceous ; 
lower pairs much reduced in size, sometimes almost petioled, the upper 2 
or 3 pairs the largest, 4-4 in. long, rarely more, green on both sides, upper 
surfaces glabrous or very slightly pilose, lower surface or rhachis pilose 
with silky hairs. Scape 34-54 in. long; stout, erect, smooth and glabrous, 
reddish-purple. Flowers hermaphrodite in all the specimens seen by me. 
Sepals 4, oblong, obtuse or subacute, sparingly pilose on the outside, ¢ in. 
long. Anthers 4, filaments exceeding the sepals when mature, broadly 
oblong, 51; in. long, dark-purple. Spines 4, subequal, $—9 in. long, exceeding 
the sepals, furnished with yellowish barbs at the top, shaft smooth, dark- 
purple. Stigma bilaterally plumose, 4in. long—Hook. f. Fl. Antarct. 1

A. adscendens is a widely distributed species outside New Zealand. It is found in 
Patagonia, Fuegia, Falkland Islands, Kerguelen Island, Crozets, and South Georgia. 
Certain specimens from the mountains of the South Island of New Zealand were 
referred to it by Hooker in the Handbook, but these are now considered to be distinct. 
Bitter, in his recently published monograph, has described them as new specie, under 
the names of A. saccaticupula, A. hirsutula, and A. fissistipula, under which names 
they will be found in this work. 
3. A. hirsutula Botter Monog. Gattung Acaena (1910) 246.— Stems 
slender, creeping, branched above; branches suberect. Leaves 1-2 in.
