Easily distinguished from all other species by the narrow-linear 3-winged carpels and the 

 transversely-articulated leaf-segments, which, although pungent, are much less rigid than those of 

 A. Colensoi. 



5. A. Hookeri, n. s. Erect. Scape 5in.— 9in. high. Leaves 3in.— 6in. 

 long, rigid, curved outwards for the upper half of their length, 2-pinnate ; 

 leaflets in 2—5 pairs, rather crowded, iin— l^in. long, divided into rigid almost 

 terete grooved spreading abruptly - acuminate pungent segments iia.— i in. 

 long; rhachis concave above; petiole exceeding the blade, almost flaccid ; sheath 

 narrow, dilated at the base, with 2 spines at its mouth. Male scapes leafy 

 below; umbels in the axils of the leafy pinnate spinous bracts, lin.— Sin. long 

 or more ; primary peduncles equalling the dilated portion of the bract, solitary 

 or with 1—3 shorter peduncles in the same axil ; rays unequal, often racemose, 

 5— 10-flowered ; flowers minute ; calyx-teeth nearly obsolete ; involucral bracts 

 as long as the slender pedicels. Female : umbels and fruit not seen.

One of the most remarkable species in this singular genus, easily recognised by the very short 

 pungent segments. Barely the leaves are reduced to 1 or 2 pairs of entire acicular leaflets. A plant 

 of vfhioh imperfect specimens were collected by Dr. Gaze on mountains near Westport may be 

 identical, but the segments are rigid. 



6. A. Lyallii, Hook. /., Handbk. 92. The entire plant polished and 

 shining, yellow. Scape 6in.— 12in. high, |in.— fin. in diameter, naked below, 

 deeply grooved. Leaves numerous, 3in.— 5in. long, pinnate ; leaflets in 1—4 

 pairs, coriaceous, rigid, j^'gin.- ^?^in. broad, pungent; petiole-sheath narrow, 

 with 2 short spines at its mouth. Male umbels compound, paniculate ; 

 peduncles lin.— 3in. long in the axils of 3— 5-partite or entire spinous bracts as 

 long as the peduncles ; rays 6—10, subequal, slender ; pedicels short. Female 

 umbels restricted to the upper part of the scape, almost hidden in the base of 

 the polished tumid bracts. Carpels narrow-oblong, 5-winged, Jin. long. —

In the leaves and male inflorescence this species approaches A. Monroi, but the leaf segments 

 are more acute. The female inflorescence is very different. 



7. A. Kirkii, Buch. in Trans. N.Z.I, xix. (1886) 214, t. xxii. Scape 

 erect, 8in.-12in. high, rather stout, naked below, grooved. Leaves all radical, 

 brown, 5in.— 9in. long, almost fin. broad, quite entire or 2— 3-foliolate, very thick 

 and coriaceous, striated, subacute, abruptly apiculate, pungent ; petiole-sheath 

 short and narrow, jointed at its junction with the blade. Male umbels with 

 long 5-partite bracts. Female inflorescence contracted, 2in.— 3in. long; 

 umbels in the axils of coriaceous simple or 2— 3-fid coriaceous pungent bracts, 

 5— 10' flowered, sometimes with 2 or 3 pedicellate flowers at the base; peduncles
