1. O. Colensoi, Hook. f. FI. N. Z. i. 92. Very variable in stature, 
from 2-10 in. high, glabrous or pilose. Leaves numerous, linear-oblong, 
pinnate or 2-pinnate ; leaflets opposite, sessile or petioled, -1— i in- broad, 
broadly oblong, inciso-serrate or inciso-pinnatifid, turning brown when dry ; 
petioles wiry ; sheaths short, membranous. Scapes several, pubescent or 
woolly, especially upwards, where the hairs point downwards. Involucre of 
6-8 ovate leaflets, ^ in. long. Flowers small, white, almost sessile in the 
involucres ; pedicels very short, elongating in fruit to 1 in. or less. Fruit 
quite glabrous. 
Northern Island: mountainous districts of the east coast and interior, abundant ii: 
grassy plains, etc. Middle Island : Waimakeriri county, 2500 ft., and Kowai river, 
Haast. 
2. O. Haastii, Hook.f., n. sp. Very similar to O. Colensoi, but more 
flaccid. Leaves pinnate, with the leaflets more membranous, petioled, 
broadly ovate, variously lobed or 3-foliolate. Fruit linear, densely tomentose ; 
pedicels usually shorter than the involucral leaves. 
Middle Island : Mount Darwin, alt. 3200 ft., Haast. 
3. O. ramosa. Hook. /., n. sp. Stem 6-24 in. high, much-branched 
from the base, and branches very slender, glabrescent or pilose. Leaves pin r 
nate or 2-pinnate, ovate-oblong in outline ; leaflets or primary divisions in few 
pairs, opposite, long petioled, \ in. long, ovate, deeply 3-5-lobed or partite 
or again pinnate, the lobes obtuse, membranous pilose ; petioles general and 
partial very slender. Umbels 6-8 - flowered ; peduncles axillary, usually 
shorter than the leaves ; involucral leaves small. Flowers nearly sessile. 
Fruits unequally pedicelled. in. long, very narrow, glabrous. 
Middle Island : Otago, river flats in the lake district. Hector and Buchanan. 
7. ACIPHYLLA, Forst. 
Erect, simple or branched, glabrous, rigid, spinescent, dioecious or polyga- 
mous herbs, sometimes tremendously armed throughout with long, rigid, 
skewer- or sword-like, spinose leaves. Leaves very thick and coriaceous, with 
sheathing bases, pinnate or 2-3-pinnate, the rhachis jointed at the insertion of 
the leaflets. Umbels densely fascicled or spicate or panicled; males panicled, 
on spreading, slender peduncles, oblique ; females usually shortly peduncled, 
in the sheaths of bracteal leaves. Involucres spinescent. Flowers unisexual ; 
males with imperfect ovaries and large depressed stylopodia ; females with 
longer ovaries and erect, tumid stylopodia. — Calyx-tube ovoid or oblong ; limb 
5 -toothed, often unequally, or obsolete. Petals incurved, without an indexed
