198 UMBELLIFERZ. [Hydrocotyle. 
distinctly 5—7-lobed; lobes sharply toothed, usually hispid on both 
surfaces but sometimes glabrescent, firm or almost coriaceous; 
petioles rather stout, 1-2 in. long, usually pilose above with reversed 
hairs. Peduncles longer or shorter than the leaves; umbels 5—40- 
flowered. Flowers sessile or nearly so. Fruits usually densely 
crowded, minute, 5-4, in. diam., red-brown; carpels acute at the 
back, with an acute keel or ridge on each face.—A. Cunn. Precur.

KeRmMaveEc Isnanps, NortH AND SoutH IsLANDs, CHATHAM ISLANDS: Abun- 
dant throughout, ascending to 2000 ft. November—March. 
Closely allied to H. nove-zealandia, but separated by the distinctly lobed 
leaves, by the lobes being acutely toothed, and by the much smaller crowded 
fruits, which are sharply keeled on the back. 
8. H. microphylla, A. Cunn. Precur. n. 496.—Glabrous or with 
a few loose hairs on the petioles and peduncles. Stems 1-3 in. long, 
slender or rather stout at the base, creeping and rooting, often 
matted. Leaves ;4-+in. diam., orbicular-reniform with usually a - 
closed or narrow sinus, 5—7-lobed ; lobes shallow, rounded, obtusely 
crenate ; petiole 41-4in. long; stipules rather large for the size of 
the plant. Peduncles variable in length, longer or shorter than the 
leaves ; umbels 2-6-flowered. Flowers sessile or nearly so. Fruit 
minute, glabrous, ;4,-;in. diam.; carpels rounded at the back, 
with an obscure rib or groove on each face.—Hook. f. Fl. Nov. Zel.

Nort AND SoutH Isuanps, Stewart IsLAND : From Mongonui southwards, 
but apparently local. December-February. 
Cunningham’s original description is not at all good, and without access to 
his specimens I cannot be certain that the plant described above is the same as 
his. It differs from H. nove-zealandie in the smaller size, glabrous and more 
deeply divided leaves, few-flowered umbels, and smaller fruit. From H. moschata 
it is at once removed by the round-edged carpels. 
9. H. asiatica, Linn. Sp. Plant. 234.—Very variable in size. 
Stems rather stout, much branched, creeping and rooting at the 
nodes. Leaves fascicled at the nodes, +-1in. diam., orbicular or 
oblong-reniform, cordate or almost truncate at the base, sinuate- 
toothed or nearly entire, glabrous or slightly pubescent; petioles 
very variable in length, 4-6in. or more, often laxly pubescent 
above. Peduncles short, 1-lin. long, rarely more; umbels 2-4- 
flowered ; bracts 2-3, broad, ovate. Fruit $-1in. diam. ; carpels 
with about 3 stout ribs on each face, but often showing the second- 
ary ribs when young, somewhat reticulated, margins obtuse. —
