A very singular and distinct species. It can be recognized at a glance by the short. 
flat squarrose ultimate segments of the leaf, which are flat or concave above, but keeled 
beneath, and which give the tips of the leaves a curious trifid appearance quite foreign 
to the rest of the genus. 
7, A. Lyallii Hook. f. Handb. N.Z, Fl. (1864) 92.—Stems stout, erect, 
leafy, 1-2ft. high or more, $-3in. diam., strongly erooved. Leaves. 
numerous, erect, variable in size, 9-18in. long, pinnate with 1-4 pairs of 
pinnae and a terminal one, very rarely bipinnate at the base; leaflets 
3-9 in. long, variable in width, 35-7 in. broad, rigid and coriaceous, gradually 
narrowed into a long acuminate pungent point, striate, midrib canaliculate ; 
margins minutely and regularly crenulate. Petiole as long as or longer 
than the lamina; sheath shorter than the petiole, broad and membranous 
at the base, produced above into 2 long and narrow rigid subulate points. 
Inflorescence long and narrow, stout and rigid, 5-12 in. long, 15-4 in. broad 
including the bracts ; males more lax and slender than the females, which 
are often exceedingly dense and compact. Bracts with broad membranous 
sheaths tipped with 3-5 rigid and spinous leaflets, the middle one of which 
is frequently spreading. Male umbels on slender peduncles 1-3 in. long ; 
female on much shorter peduncles, almost concealed in the sheaths of 
the bracts. Fruit narrow-oblong, tin. long; carpels 4-5-winged. Vittae 
1-2 in the interspaces, 2-4 on the commissural face.—Z. Kirk Students’

Until A. Lyallii is collected in Dusky Sound, where it was originally gathered by 
Lyall, it must remain a doubtful matter whether the plant described above is that to 
which the name of Lyallii should be applied. Our plant is much more closely allied to 
A. crenulata than any other; but is much larger and stouter, with a stem sometimes 
nearly lin. diam. at the base; the leaves are more rigid and coriaceous, and the 
inflorescence is much larger and more dense, with more rigid and coriaceous bracts. 
8, A. erenulata J. B. Armstrong in N.Z. Country Journ. (1879) 56.— 
Tall, slender, erect, smooth and shining, 1-2 ft. high, pinnate or 2-pinnate 
at the base, less rigid and coriaceous than is usual in the genus, sometimes 
almost flaccid; leaflets 1-4 pairs, spreading, 2-6in. long, ;4-+1in. broad, 
linear, striate, acuminate and pungent-pointed ; midrib often bright-red ; 
margins thickened, finely and regularly crenulate ; sheaths short and broad, 
membranous at the base, produced at the top into 2 slender spines. 
Panicle variable in length, 4-15in. long, densely many-flowered. Bracts 
very numerous, spreading or suberect; sheath often membranous, ending 
in a long slender central spine and 2 short lateral ones. Male inflorescence 
much broader and more open than the female; umbels springing from 
the axils of the bracts, compound ; peduncles and rays long and slender. 
Female inflorescence narrower and more rigid, umbels on shorter peduncles, 
crowded in the axils of the bracts. Fruit linear-oblong, 4-5-winged.—
