gradually narrowed into rigid spinous points, margins rough with minute 
serrulations ; sheaths broad, produced above on each side into a long 
pinnately divided spinous leaflet. Inflorescence a dense spike-like panicle 
composed of numerous umbels almost concealed in the axils of spinous. 
bracts ; female inflorescence much more contracted than the male. Bracts 
with a broad linear-oblong sheath tipped with 3-5 long rigid spines, the 
middle one much the longest and usually sharply refracted when the fruit.

the other with 3. Vittae 2—3 in the interspaces and 4—6 on the commissural

NortH AND Settu IstaAnps: Not We nario in mountain districts from the East: 
Cape, Mount Egmont, and Ruapehu southwards to Foveaux Strait. Usually between 
1000 and 3500 ft., but descends to sea-level in several localities. Taramea; Kuri-

The very narrow leaflets and numerous bracts with long and narrow spinous 
segments, the middle one of which is sharply refracted, easily distinguish this from all 
the forms of A. Colensoi. Both species yield an aromatic gum resin, which was formerly 
used by the Maoris as a masticatory. Mr. Petrie gives the name of robusta to a stout 
form not uncommon in many localities, but the differences appear to me to be trivial.

erect, 1-3 ft. high, 1-2in. diam. at the base, grooved, purplish below. 
Radical leaves numerous, 6-30 in. long, pinnate ; leaflets 2-4 pairs, 4—15 in. 
long, 4-4in. broad, narrow-linear, pungent-pointed, coriaceous, “#riate, 
conspicuously transversely articulate, margins smooth or nearly gp ; petioles. 
4-10 in. long, sheaths broad, terminated by 2 short spines aboWejjy Bracts 
with a broad rather membranous sheath tipped with a simple or 33tidlepflet ; 
lobes hardly pungent. Umbels very numerous, solitary or two together in 
the axils of the bracts; males on peduncles 1-5 in. long, forming a rather 
open panicle ; females on much shorter stalks and inflorescence much more 
dense. Flowers often polygamous. Fruit narrow linear-oblong, 2 in. long ; 
carpels one 4-winged and the other 3-winged. Vittae 1-2 in the interspaces.

Closely allied to A. Colensoi, from which it principally differs in the less rigid and 
transversely jointed leaf-segments, thinner and scarcely pungent bracts, and narrower 
fruit.
