17. A. pinnatifida Petrie in Trans. N.Z. Inst. xl (1911) 254.— 
Rhizome branched, creeping in wet ground, putting up numerous short 
flowering stems. Leaves many, all radicle, 4-8in. long, more or less 
flaccid, quite glabrous, 3-foliolate; primary divisions divergent, the 
middle one the longest, deeply and regularly pinnatisect ; segments narrow- 
linear, remote, decreasing in length regularly from the base to the summit, 
‘quite entire, midrib and margins thickened, apex acuminate, subpungent. 
Flowering stems short, often not exceeding the leaves. Bracts large for 
the size of the plant; sheaths more than $ the length of the bract, 
broad, smooth, inflated, concealing the inflorescence ; tip of sheath crowned 
with a short sessile trifoliolate leaflet similar to the leaves but smaller. 
Male inflorescence more lax than the female, with the sheaths of the 
involucral bracts much narrower, and not so much inflated. Umbels 
compound; primary peduncles exceeding the sheaths. Fruit linear- 
oblong ; carpels 3-5-winged.

Although very different in habit and appearance, the nearest ally of this curious 
plant is undoubtedly A. Cuthbertiana, of which it has the very distinctive inflorescence. 
18. A. Heetori Buch. in Trans. N.Z. Inst. xiv (1882) 346, t. 27.— 
Stem 10-16in. high, stout, deeply grooved. Leaves numerous, 3-6 in. 
long, trifoliolate or rarely pinnate with 2 pairs of leaflets; leaflets 
1$-4in. long, $-+in. broad, narrow-linear, suddenly narrowed into a 
spinous point, smooth, rigid and coriaceous, striate; margins thickened, 
entire or serrulate ; sheaths long, narrow, produced at the top into 2 very 
long leaflets almost equalling the leaves proper. Inflorescence forming 
a contracted spike-like panicle 2-5in. long. Male umbels on slender 
peduncles; female on much shorter ones, crowded in the axils of the bracts. 
Bracts with long narrow sheaths and 3 narrow spinous leaflets. Carpels 
linear-oblong, 3-5-winged.—Cheesem. Man. N.Z. Fl. (1906) 211.

Mr. Kirk reduced this to A. Lyallit in the ‘“‘ Students’ Flora,” but it differs from 
that species in the trifoliolate leaves, and in the leaflets at the top of the leaf-sheath 
being almost as long as the leaves proper, whereas they do not reach the “base of the 
lowest pinnule in A. Lyallii. 
19. A. Kirkii Buch. in Trans. N.Z. Inst. xix (1887) 214, t. 17.—Stout, 
erect, smooth and polished, 6-12in. high. Leaves all radical, yellowish- 
brown, 4-9 in. long, +-4in. broad or more, simple or forked or 3-foliolate, 
excessively thick and coriaceous, suddenly narrowed into a short spinous 
point, finely striate, striae often connected by irregular cross - veinlets ; 
margins much thickened ; sheath short and narrow, membranous, grooved, 
jointed at its junction with the blade. Flowering stem short, stout, grooved, 
naked below. Bracts very numerous, the lower ones 3-foliolate, pungent- 
pointed ; the upper often simple, all rigid and coriaceous. Male umbels 
shortly pedunculate ; females almost sessile in the axils of the bracts. 
Fruit linear-oblong, + in. long, carpels 4—5-winged. Vittae 1-2 in the inter- 
spaces, 4 on the commissural face——T. Kirk Students’ Fl. (1899) 209:
