crenate; petioles slender, 1–4 in. long. Peduncles rather slender, shorter than the leaves; umbels 3–8-flowered. Flowers shortly pedicelled or almost sessile. Fruit large, flat, broader than long, notched above and below, often mottled; carpels with one rib on each face, and with the dorsal edge expanded into a broad wing.—Hook. f. Fl. Tasm. i. 153, t. 33; Handb. N.Z. Fl. 86; Kirk, Students Fl. 188.
North and South Islands: In lowland swamps from Mongonui to North Canterbury, but often local. December–February. Also in Victoria and Tasmania.
6. H. novæ-zealandiæ, D.C. Prodr. iv. 67.—Very variable in size and habit of growth. Stems 3–12 in. long, much or sparingly branched, open or matted, creeping and rooting at the nodes, sometimes ascending at the tips, pilose or almost glabrous. Leaves ¼–1¼ in. diam., orbicular-reniform with usually an open sinus, obscurely 5–9-lobed or -angled; lobes shallow, obscurely and obtusely crenate, rarely more acutely toothed, usually membranous but sometimes subcoriaceous, sparingly hairy or nearly glabrous; petioles ½–3 in. long, slender, usually pilose with reversed hairs above. Peduncles shorter than the leaves; umbels 5–12-flowered. Flowers shortly pedicelled. Fruit 112 in. diam., broader than long, somewhat flattened, glabrous, pale-brown, sometimes mottled; carpels rounded at the back, with an indistinct rib or groove on each face.—A. Cunn. Precur. n. 497; Raoul, Choix, 46; Hook. f. Fl. Nov. Zel. i. 83; Handb. N.Z. Fl. 86; Kirk, Students' Fl. 189. H. dichondræfolia, A. Cunn. l.c. n. 498. H. intermixta, Col. in Trans. N.Z. Inst. xvii. (1885) 240. H. alsophila, Col. l.c. xviii. (1886) 261. H. involucrata, Col. l.c. xix. (1887) 262. H. amœna, Col. l.c. xxi. (1889) 83.
Var. robusta.—Stems stout, suberect above. Fruit large, 18 in. broad, turgid; carpels with a groove on each face.—H. robusta, Kirk, Students' Fl. 189.
Var. montana, Kirk, l.c.—Stems stout, creeping, densely matted. Leaves usually with a narrow sinus, coriaceous, glabrous or nearly so, lobes shallow. Carpels with a groove on each face.
North and South Islands, Stewart Island: Abundant throughout, var. montana ascending to quite 4,000 ft. Var. robusta: Sandy beaches north of Auckland, rare. November–March.
A very variable plant, but one that can generally be recognised without much difficulty by the shallow and rounded lobes of the leaves, and by the compressed fruits with thick obtuse margins. I am unable to maintain Mr. Kirk's H. robusta as a separate species, the differences between it and the typical state being of a very trivial character. Closely allied to it is a large-leaved species gathered by Mr. Cockayne in forests in the Chatham Islands, in which the leaves are sometimes 2 in. diam.
7. H. moschata, Forst. Prodr. n. 135.—More or less hispid or pilose, rarely almost glabrous. Stems 2–12 in. long, much branched, often densely matted, creeping and rooting at the nodes. Leaves 16–1 in. diam., reniform or orbicular with usually an open sinus,
