210 UMBELLIFERZ. [Aciphylla. 
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. 
3. A. Traversii, Hook. f. Handb. N.Z. Fl. 729.— Stem stout, 
erect, 1-3 ft. high, 1-2 in. diameter at the base, grooved, purplish 
below. Radical leaves numerous, 6-30in. long, pinnate; leaflets 
2-4 pairs, 4-15in. long, $-4in. broad, narrow-linear, pungent- 
pointed, coriaceous, striate, conspicuously transversely articulate, 
margins smooth or nearly so; petioles 4-10 in. long, sheaths broad, 
terminated by 2 short spines above. Bracts with a broad rather 
membranous sheath tipped with a simple or 3-fid leaflet; 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 inflor- 
escence much more dense. Flowers often polygamous. Fruit 
narrow linear-oblong, 2in. long; carpels one 4-winged and the 
other 3-winged. Vitte 1-2 in the interspaces and 3-5 on the 
commissural face.—Kirk, Students’ Fl. 208. Gingidium Traversii,

Taramea. November—December. 
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. 
4. A. Hookeri, 7. Kirk, Siudents’ Fl. 209. — Erect, 4-12 in. 
high. Root long, stout, fusiform. Radical leaves numerous, often 
curved outwards at the tip, 2-8in. long, pinnate or 2-pinnate; 
primary leaflets 2-5 pairs, crowded or rather remote, 4-14 in. 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 
half 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, tin. long; carpels 4—5-ribbed.

A very singular and distinct species. It can be recognised at once by the 
short flat almost squarrose leaf-segments.
