A genus almost confined to the south temperate zone, most frequent in Australia, found 
also in subtropical India, China, and Japan. One NewZealaud species is also found in Juan 
Fernandez.

1. H. alata, Jacq. ; — Ft. N. Z. i. 63. Stem herbaceous, erect or pro- 
cumbent at the base, branched, 4-angled, 1-3 ft. high ; branches suberect, 
slightly scabrid. Leaves opposite, sessile or petioled, ovate-lanceolate, acute 
or obtuse, very coarsely deeply serrate, coriaceous, slightly rough to the 
touch, |-1^ long. Flowers minute, green, in leafy slender terminal racemes, 
solitary or whorled, on short curved pedicels, drooping, T \ in. long. Calyx 
4-angled, with 4 small lobes. Petals twice as long as the calyx-lobes. 
Nut small, with 4 narrow wings, green; sides smooth or wrinkled. Stigmas 
conical, not plumose. — Cercodia erecta, Murr. ; C. allernifolia, A. Cunn. 
Abundant ou dry hills in various localities throughout the islands, Banks and Solander, 
etc. ; ascending to 2000 ft. Also found in Juan Fernandez. 
2. H. tetragyna, Labill.; — FI. N. Z. i. 62. A suberect or prostrate, 
slender, branched herb, everywhere scabrid with short, hispid pubescence; 
branches slender, 2-8 in. long. Leaves all opposite, shortly petioled i in. 
long, ovate or lanceolate, acute, sharply serrate, rigidly coriaceous, scabrid 
on both surfaces. Flowers minute, sessile, solitary in the axils of the upper 
leaves. Nut ovoid, ^ bi. long, 8-angled, muricate. Stigmas plumose. — 
Goniocarpus tetragyna, Labill. FI. Nov. Holl. i. t. 53; Cercodia incana, A. 
Cunn. 
Var. a. Branches suberect. Leaves |-J in. long, many-toothed. 
Var. j 8 . diffusa. Branches diffuse, prostrate. Leaves 5-5 iu. long, broader, obtuser, with 
fewer teeth. 
Northern Island : on dry hills ; a, Bay of Islands ; /9, common there and at Auckland. 
I have seen no Middle Island specimens. Var. a is a native of Tasmania and Southern Aus- 
tralia, also of China ( G.scaber , Koenig), Borneo, and the mountains of East Bengal. 
3. H. depressa, Hook.f. FI. N. Z. i. 63. A very slender, prostrate, 
branched herb, slightly scabrid with short white hairs; branches 1-12 in. 
long, wiry, almost filiform. Leaves sessile, broadly ovate, subacute, | in. 
long, with 3-5 deep close serratures on each side, slightly scabrid on both 
surfaces, coriaceous. Flowers solitary, axillary or subterminal, sessile. Nut 
■§• in. long, 4-angled, or obscurely 4-8-costate, smooth or wrinkled, but not 
muricate. Stigmas plumose.— Goniocarpus depresses, A. Cunn. 
Common on dry hills, throughout the islands. Readily distinguished from G. tetragyna 
by being almost glabrous and very slender. In the New Zealand Flora I considered this as 
the same with the Tasmanian II. (Goniocarpus) serpyltifolius. Hook. Ic. PI. t. 290, and it
