closely branched panicle 6-15 in. long ; bracts many, crowded, erect, the 
lower pinnately divided, the upper almost entire. Fruit linear-oblong,

Probably A. Colensoi is the nearest ally of this species. It differs from A. Monroi, 
with which it has been compared, in the taller and stouter stem, and in the narrower 
male inflorescence. 
5. A. indurata Cheesem. in Trans. N.Z. Inst. xlvu (1915) 40.—Root 
long, stout, tapering, often as thick as the thumb at the top. Stem stout, 
erect, 11-2 ft. high, 1-1 in. diameter or more at the base. Radical leaves 
numerous, 1-1} ft. long, pinnate with most of the pinnae trifoliolate or 
rarely the lowest again pinnate, the uppermost usually simple; pinnae 
4-6 pairs, 3-6 in. long ; ultimate segments 2-5 in. long, 4-4 1n. broad, linear, 
occasionally squarrose but not conspicuously so, flat or slightly concave, 
very rigid and coriaceous, gradually narrowed into long rigid and pungent 
points ; midrib very stout, scaberulous above ; margins much thickened, 
cartilaginous, rough with minute serrulations. Petiole equalling or shorter 
than the blade, upper portion rigid and concave, below broader and 
sheathing and less coriaceous. Bracts very numerous, rigid, squarrose 
and spreading ; the lower ones with a sheathing base }-4 in. broad, tipped 
with a pinnate leaflet 1-2in. long; upper gradually becoming smaller with 
narrower and more pungent segments; uppermost tipped with a trifid 
leaflet 1-Idin. long, the segments very narrow-linear and spinous. 
Inflorescence compact, narrow linear-oblong, 8-12 in. long, female slightly 
narrower than the male. Umbels very numerous compound, more or less 
concealed within the sheathing bracts. Fruit linear-oblong, not seen in 
a perfectly mature state.

So far, this species has only been gathered by Mr. Townson in the localities quoted 
above. It is clearly allied to A. Hookeri, but is a much larger and more rigid and 
coriaceous plant, with the ultimate segments many times longer and considerably 
broader, and not conspicuously squarrose. The inflorescence is also much larger and 
broader, and altogether the aspect of the plant is very dissimilar. Mr. Townson’s 
specimens from Mount Bovis are smaller, and the ultimate segments of the leaves are 
shorter, showing a slight approach to A. Hookerv. 
6. A. Hookeri 7. Kirk Students’ Fl. (1899) 209.—Erect, 4-12 in. high. 
Root long, stout, fusiform. Radical leaves numerous, often curved out- 
wards at the tip, 2-Sin. long, pinnate or 2-pinnate ; primary leaflets 2-5 
pairs, crowded or rather remote, 4-14in. long, simple or forked or trifid 
or pinnately divided ; segments }-? in. long, linear, spreading or squarrose, 
flat, grooved above, rigid and coriaceous, narrowed into a spinous point. 
Petiole more than } the length of the blade, weak and flaccid below, 
with a long narrow membranous sheath produced into two short spines 
at the top. Male scape short, leafy below; bracts numerous, with long 
membranous sheaths and pinnately divided rigid acicular tips, the lowest 
sometimes 3in. long. Umbels numerous, compound, on slender peduncles 
equalling or shorter than the bract-sheath ; rays unequal. Female umbels 
much smaller, densely packed, forming a narrow contracted panicle , 
bracts much shorter. Fruit linear-oblong, 4in. long; carpels 4-5-ribbed,—
