214 UMBELLIFERS. [Aciphylla.. 
12. A. simplex, Petrie in Trans. N.Z. Inst. xxii. (1890) 440.— 
Very similar to A. Dobsoni, and with precisely the same habit, 
but differing in the leaves, which are less coriaceous and quite 
entire, 14-3in. long; lower half expanded into a broad sheath; 
blade linear-subulate, rigid and coriaceous, concave above, ob- 
tusely rounded at the tip with a short pungent mucro, transversely 
jointed and often longitudinally grooved, midrib usually evident, 
margins thickened. Flowering-stem stout, 14-3 in. long; umbels 
and flowers as in A. Dobson. Ripe fruit not seen.—Kirk, Stu- 
dents’ Fil. 211.

Mountains, Petrie! 5000-6000 ft. February. 
13. A. Dieffenbachii, Kirk, Students’ Fl. 211. —Stem stout, 
erect, 2-3 ft. high, 1-l}in. diam. at the base, grooved. Leaves 
all radical, 1-2 ft. long, 4-8in. broad, flaccid, grevish-green, 3—4- 
pinnate; petiole usually more than half the length, sheath with 
two blunt lobes at the top ; blade oblong or ovate-oblong in outline ; 
primary pinne 4-5 pairs; segments 14-3 in. long, #4, in. broad, 
linear, flat, striate, mucronate. Inflorescence broad, loosely pani- 
culate, of numerous pedunculate compound umbels. Bracts with a 
broad sheath and rather large pinnatisect lamina. Pedunceles 
2-5in. long; rays of the male umbels numerous, slender, of the 
females about 6; involucral bracts few, linear-subulate. Fruit 
large, 2in. long, Zin. broad, broadly oblong, much dorsally com- 
pressed ; carpels one 3-winged and the other 2-winged, rarely both 
3-winged. Vitte 1 in each interspace and 2 on the commissural 
face. — Ligusticum Dieffenbachii, Hook. f. Handb. N.Z. Fl. 729.

CHatHAM IsuANDS: Rare, H. H. Travers! F. A. D. Cox! 
The fruit of this is quite unlike that of Aciphylla, Ligqusticum, or Angelica, 
to all of which genera it has been referred. Mr. Kirk is probably correct in con- 
sidering that it will ultimately form the type of a new genus. 
9. LIGUSTICUM, Linn. 
Perennial herbs, often large and stout, usually with aromatic or 
strong-smelling foliage or roots. Leaves 1—-2—3-pinnate or ternately 
divided; rhachis articulated at the insertion of the leaflets. Umbels 
compound, rarely simple, usually of many rays; involucral bracts 
few or many, sometimes wanting. Flowers white or red, polygam- 
ous or dicecious. Calyx-teeth small or obsolete. Petals incurved 
at the tip. Fruit linear-oblong, oblong, or ovate-oblong; carpels 
rounded or dorsally compressed, each with 6 equal narrowly 
winged ridges, or one carpel 5-4-winged, the other 4~3-winged. 
Vittze usually numerous in the interspaces in the northern species, 
seldom more than 1 in each interspace in the southern.
