84 FLORA OF NEW ZEALAND. [ Umbellifere. 
spicuous. Leaves scattered; petioles 4-1 inch long; lamina 4-3 inch broad, broadly reniform-orbicular, five- to 
seven-lobed, sharply toothed. Peduncles shorter and more slender than the petioles. Carpels dark brown, very 
small. —Z. virta, Br., of Australia and Tasmania, seems intermediate between this and H. Nove-Zelandie. The 
var. compacta has the leaves more deeply lobed, and the lobes more deeply and sharply cut.

formi-orbiculatis laxe pilosis 5—7-lobis, lobis 3—5-dentatis, pedunculis glabris petiolo «equilongis, capitulis

Prodr. 
Has. Northern Island. Probably common, but overlooked from its small size, Cunningham, 
Colenso. 
A very small, rather stout, short-stemmed, tufted, depressed plant, sparingly hairy. Petioles 4 inch long. 
Leaves + inch broad, variously lobed to about one-third their breadth ; lobes bluntly but coarsely toothed. ^ Capitula 
very small, red-brown, hardly 1 line diameter, of many crowded sessile fruits. Carpels as in H. moschata. 
8. Hydrocotyle dissecta, Hook. fil.; pubescens, caule tenello, foliis reniformi-orbiculatis 5-7-partitis 
segmentis obovatis v. cuneatis laceris et inciso-dentatis, pedunculis gracilibus, capitulis multi (40—50)-floris, 
fructibus dense congestis parvis? carpellis utrinque obscure 1-costatis dorso convexis. 
Has. Northern Island, Colenso. 
I have only imperfect specimens of this most distinct-looking plant. Stems slender, hairy, almost hispid, as 
are the petioles, peduncles, and leaves, especially underneath. Leaves alternate or fascicled ; petioles 1 inch long; 
lamina 3 inch broad, cut to near the base into five spreading, obovate, cuneate divisions, which are deeply lobed on 
the sides and margin, and sharply inciso-dentate. Peduncle slender, shorter than the petiole. Capitulum pale, 
globose, of forty to fifty densely-packed small fruits. Carpels one-ribbed on each side, rounded at the back.— Some 
latitude must be allowed for this description, which is drawn up from imperfect materials. The plant is allied to 
H. moschata. 
$ e. Peduncles elongated. Flowers pedicellate. 
9. Hydrocotyle elongata, A. Cunn.; pilosa v. glabrata, tenella, caule elongato, stipulis parvis, foliis 
late orbiculari-reniformibus profunde 5—7-lobatis, lobis ovatis argute dentatis, pedunculis gracilibus petiolo 
longioribus, umbellis multifloris, pedicellis elongatis radiatis, floribus minimis, fructibus parvis late didymis 
brunneis, carpellis utrinque 1-costatis. 4. Cunn. Prodr. 
Has. Northern and Middle Islands. From the Bay of Islands, Cunningham, etc., to Dusky Bay, 
Lyall. 1 
A very distinct species from any other New Zealand one, but very near an Andes plant. Stems slender, 8-10 
inches long in large specimens, more or less hairy, as are all other parts of the plant except the flowers and fruit. 
Petioles 1-2 inches long. Leaves 3-13 inch broad, deeply five- to seven-lobed ; lobes sharply toothed. Peduncles 
considerably longer than the leaves, very slender. Umbels twenty- to fifty-flowered. Flowers very minute, on 
slender strict pedicels, 3-3 lines long. Fruit dark brown, broadly didymous, very small. Carpels with one rib on 
each side.
