508 ROSACEAE. [ Acaena. 
long; sheaths passing into lanceolate or broadly ovate stipules which are 
simple or 2—3-fid; petiole and median rhachis furnished with laxly or 
densely set hairs. Leaflets 11-15; the lower ones entire or 2-3-fid; the 
upper obovate, obtuse, 13-16-dentate; the whole lamina  greyish- 
glaucescent.on both surfaces, the upper surface a little greener and laxly 
clothed with appressed hairs; under-surface densely hairy throughout, 
especially on the primary and,secondary veins, pilose on the margins, 
but no pencils of hairs on the apices of the teeth. Scape erect, pilose 
with crisped hairs which are most abundant and appressed just below 
the capitulum, which is }in. diam. Sepals 4, almost glabrous. Stamens 2 ; 
anthers reniform, broader than long, purplish. Spines 4, armed at the 
tip with 5-7 barbs. 
Var. hirtieupula Bitter I.cLarger and coarser; leaves 1j—-2in. long; stipules 
broader. Scape 6in. high. Cupule hirtulose. 
Var. glabricupula Bitter 1.c.—Smaller and more compactly branched; leaves 
smaller, }-i} in. long. Cupule nearly glabrous. 
Sourn Istanp: Canterbury—According to Bitter, both varieties collected by 
Cockayne at Trelissick, Broken River basin, alt. 2100 ft. 
I have not identified this species, and, in the absence of other information, the 
above description is condensed from that given in Bitter’s monograph. According 
to him, it is one of the species included by Hooker in his circumscription of A. adscendens. 
4. A, fissistipula Bitter Monog. Gattung Acaena (1910) 247.—Stem small, 
slender, creeping; branches ascending or suberect, glabrous or nearly so, 
more or less rubescent. Leaves mostly on the creeping stem, 13-3 in. 
long; stipules short, 3-5-fid, glabrous except a pencil of hairs at the tip 
of the lobes; petiole and median rhachis more or less pilose with whitish 
hairs. Leaflets 9-13; lowest pair very small, entire or 3-fid; following 
pairs gradually larger, uppermost leaflet the largest, orbicular or nearly 
so, tin. diam.; deeply 7—-13-toothed; the whole lamina glaucescent on 
both surfaces, sometimes faintly rubescent on the margins, upper surface 
glabrous or nearly so, under-surface appressed-pilose on the veins, a dense 
pencil of hairs on the tips of the teeth. Scapes 5-7 in. long, naked or 
with a very minute leaflet, rubescent, below almost glabrous, in the upper 
portion densely covered with appressed-pilose hairs. Flower-head } in. 
diam., reddish-purple. Sepals 4, green suffused with purple, pilose without ; - 
cupule densely pilose; spines 4. Stamens 2; anthers purple, reniform, 
a little broader than long. Stigma bilaterally plumose. 
Soutn Istanp: Canterbury—Broken River basin, alt. 2500 {t., 7. F.C. Otago— 
- Hector Mountains, alt. 5000 ft., Peirie (quoted in Bitter’s monograph). 
This appears to be a sufficiently well-marked species, although doubtless closely 
allied to A. hirsutula. The dense pencils of whitish hairs terminating the teeth of 
the leaves and the pilose calyx are very curious charactérs. I have been acquainted 
with it for many years, but, like most New Zealand botanists, have treated it and 
other allied plants as a variety of A. adscendens. Bitter describes two varieties— 
longibracteata, in which the bracts of the capitulum exceed the flowers, and brevi- 
bracteata, in which the bracts are shorter than the flowers. But the last-mentioned 
variety is only known in cultivation in England and Germany. 
5. A. novae-zelandiae 7. Kirk m Trans. N.Z. Inst. mi (1871) 177.— 
Stem long, creeping and rooting, stout and woody at the base ; branches 
leafy, ascending at the tips, more or less silky-pilose, often rubescent.
