6. H. uniflora 7. Kirk in Trans. N.Z. Inst. ix (1877) 548.—Stems 
creeping and rooting, often subterranean and putting up numerous densely 
matted branches forming a compact sward an inch or two in height. 
Leaves small, opposite, }-+in. long, sessile or shortly petioled, ovate or 
ovate-oblong to lanceolate, sparingly covered with appressed pilose hairs, 
thinly or thickly coriaceous, acute, margins thickened and. furnished with 2 
or rarely 3 sharp serratures on each side. Flowers minute, axillary and 
opposite, usually 1-2 pairs on a branch, sometimes solitary and terminating 
the branch, sessile or shortly peduncled. Calyx-tube ovoid, tetragonous, 
smooth and polished; lobes 4, triangular. Stamens 4 or 8. Fruit shining, 
smooth and polished, tetragonous, not muricate.—H. uniflora var. genuina

Norru AND Soutn IsLanps, Stewart Isuanp: Not uncommon from Rotorua and 
Taupo southwards. Sea-level to 3500 ft. Flowers most of the year. 
In the first edition of this work I kept this as a variety of H. depressa, to which 
it is certainly very closely allied. But it differs in the smaller size, usually narrower 
leaves, and fewer flowers, which are generally axillary and opposite, but sometimes 
solitary and terminal. 
7. H. micrantha R. Br. ex Sieb. and Zucc. Fl. Jap. i (1848) 25.—A tufted 
much-branched procumbent or ascending herb 2-6in. high; stems and 
branches slender, wiry, glabrous or slightly scaberulous. Leaves opposite, 
very shortly petioled, 4-4 in. diam., broadly ovate or almost orbicular, obtuse 
or subacute, coriaceous, crenate-serrate, the crenatures broad and rounded. 
Flowers minute, drooping, in slender almost filiform racemes terminating 
the branchlets; pedicels very short. Petals 4, more than twice as long 
as the triangular calyx-lobes. Fruit 34 in. long, broadly oblong, 8-costate, 
interspaces smooth and shining.—Hook. f. Handb. N.Z. Fl. (1864) 66;

NortH AND SoutH IsLanps, STEwART Istanp: Abundant from the North Cape
