2. H. tetragyna, Hook. f. Fl. Nov. Zel. i. 62.—A rigid and 
wiry much-branched herb 6-15 in. high, usually scabrid with white 
appressed hairs; stems prostrate or decumbent at the base, erect or 
ascending above, tetragonous. Leaves opposite, shortly petioled, 
13 in. long, elliptical-ovate or oblong to lanceolate, acute, sharply 
serrate, coriaceous; floral leaves or bracts usually alternate. 
Flowers minute, sessile or nearly so, solitary in the axils of the 
floral leaves, forming slender leafy terminal spikes, which are some- 
times branched and paniculate. Stamens 8. Styles 4; stigmas 
plumose. Fruit ;4in., broadly ovoid, 4—8-costate, transversely 
rugose or muricate.—Handb. N.Z. Fl. 65; Benth. Fl. Austral, ii. 
484; Kirk, Students’ Fl. 148. Goniocarpus tetragynus, Labill. Pl. 
Nov. Holl. 39, t. 58. A. Cunn. Precwr. n. 529. Cercodia incana, 
A. Cunn, lc. n. 528. 
Var. diffusa, Hook. f. Handb. N.Z. Fl. 65.— Stems slender, spreading, 
prostrate. Leaves 4-3in., broader and more obtuse, with fewer teeth. 
NortH anp SourH Isnanps, Stewart Is~tAnp: The typical form confined 
to the district between the North Cape and the Bay of Islands. Var. diffusa 
abundant throughout the Islands. The species is widely distributed in Austra- 
lia, and is also found in China and Malaya, and in the Khasia Mountains of 
India. 
3. H. depressa, Walp. Rep. ii. 99.—A small slender wiry 
much-branched herb 1-5in. high, usually seabrid with short 
white hairs; rhizomes slender, creeping, often much branched ; 
stems prostrate or suberect, tetragonous. Leaves opposite, ses- 
sile or nearly so, +-4in. long, ovate or ovate-oblong, sometimes 
almost cordate, subacute, with 1-4 deep and narrow serratures 
on each side, coriaceous, margins strongly cartilaginous; floral 
leaves similar but smaller, usually all opposite. Flowers minute, 
sessile, axillary and solitary, forming short terminal spikes. Fruit 
7 i. long, 4-angled, 4—8-costate ; interspaces smooth and shining, 
not tuberculate.—Hook. f. Fl. Nov. Zel.i. 63; Handb. N.Z. Hil. 65; 
Benth. Fl. Austral. ii. 485; Kirk, Students’ Fl. 148. H. bibracteo- 
lata, Col. im Trans. N.Z. Inst. xxii. (1890) 462. Gonicarpus de- 
pressus, A. Cunn. Precur. n. 531. 
Var. aggregata, Kirk, lI.c. 149.— Flowers clustered at the tips of the 
branches, forming small heads.—H. aggregata, Buch. in Trans. N.Z. Inst. iv. 
(1872) 224, t. 13. 
Var. serpyllifolia, Benth. Fl. Austral. ii. 485.— Stems 1-4 in., usually 
creeping and matted, often forming a dense sward. Leaves ,-tin., narrow- 
ovate to lanceolate, acute at both ends. Flowers fewer, often solitary on the 
branches. Fruit smaller.—H. uniflora, Kirk in Trans. N.Z. Inst. ix. (1877) 
548. Gonicarpus serpyllifolius and G. vernicosus, Hook. Ic. Plant. t. 290, 311. 
North snp Sour Istanps, Stewart Isnanp: Abundant throughout, 
ascending to nearly 4000 ft. Also in Victoria and Tasmania. 
A very variable plant. Some forms approach very close to H. tetragyna, 
but usually it can be easily separated from that species by the opposite flowers 
and the smooth interspaces of the fruit.
