2. H. eartilaginea Cheesem. in Trans. N.Z. Inst. xxix (1897) 390.— 
Stems numerous, stout, erect, 6-12in. high, sharply 4-angled, usually 
branched above, rough with minute asperities but otherwise glabrous. 
Leaves opposite, often decussate, shortly petiolate, broadly ovate or ovate- 
oblong, 4-2 in. long, acute, coarsely and deeply crenate-dentate, very cor- 
aceous, cartilaginous, especially at the margins, shining but scabrid, margins 
thick. Flowers small, in many-flowered racemes terminating the stem and 
branches, clustered, drooping, shortly pedicelled, furnished with 2 minute 
bracteoles. Calyx-tube obversely pyramidal; lobes 4, ovate, acuminate. 
Petals 4, not unguiculate, rounded at the apex, rather longer than the 
calyx-lobes, often wanting in the female flowers. Stamens 8; styles and 
ovules 4. Fruit broad at the base, where it is furnished with 4 short wings, 
narrowed upwards, conspicuously rugose between the wings. Seeds 4.—

Cheesem. Man. N.Z. Fl. (1906) 148. 
Norv Isuanp: Cliffs near the North Cape, not uncommon on a limited stretch 
between Tom Bowline’s Bay and the Cape. January. 
Close to the preceding species, but distinguished by the much smaller size and 
stouter habit, shorter and broader leaves, which are highly cartilaginous, and by the 
much more rugose fruit. 
3. H. incana Walp. Rep. ii (18438) 99.—A rigid and wiry erect or 
diffusely branched herb 6-15 in. high, usually scabrid with white appressed 
hairs ; stems decumbent at the base, ascending above, 4-angled. Leaves 
opposite, shortly petiolate, +-#in. long, elliptical-ovate or oblong to ovate- 
lanceolate, acute, coriaceous, scabrid with appressed hairs, sharply serrate ; 
teeth many; floral leaves or bracts often alternate. Flowers minute, soli- 
tary in the axils of the floral leaves, forming slender leafy terminal spikes, 
which are sometimes branched and paniculate. Calyx-tube elliptic, longer 
than broad, 8-ribbed, interspaces between the mbs usually rugose. 
Stamens 8. Styles 4; stigmas plumose. Fruit in. long, ovoid, 4-8- 
costate, transversely rugose.—H. tetragyna Hook. f. Fl. Nov. Zel. 1 (1853) 
62; Handb. N.Z. Fl. (1864) 65 (but not of Fl. Tasm. i (1860) 120, nor of

Nortu Isnanp: From the North Cape southwards to the Bay of Islands and 
Whangarei, not uncommon. Sea-level to 1000 ft. November—January. Appa- 
rently endemic. | 
Schindler has pointed out that this plant is distinct from the Australian 
H. tetragyna, with which it was united by Hooker. On comparing it with Australian 
specimens, I find that it differs in the smaller size, shorter and less pointed leaves 
with fewer serratures, and in the larger and narrower fruit. Schindler proposes to adopt 
Buchanan’s name of H. aggregaia. But Buchanan’s plant, of which I hold some of the 
type specimens, is referable to H. depressa, of which it has the habit, foliage, and 
distinctive fruit. _ And, in addition, there is an older name of H. incana Walp., which 
I have consequently adopted. 
4. H. procumbens Cheesem. in Trans. N.Z. Inst. xlii (1910) 202 — 
Stems slender, much branched, procumbent or even prostrate, 4-12 in. 
long; branches 4-angled, rough with minute asperities, and sparingly 
clothed with appressed hairs. Leaves opposite, shortly petioled, oblong 
or oblong-ovate, acute or subacute, rigid and coriaceous, }-4in. long, but
