1. P. heterophylla, A. Cunn. Precur. n. 402.—A tall and slender branching climber, often ascending trees to a considerable height; stems tough and pliant, in old specimens woody towards the base; young branchlets terete, more or less pubescent. Leaves extraordinarily variable in size and shape; of young plants 1–5 in. long, narrow-linear, linear- or obiong-spathulate, or linear-oblong, entire or irregularly sinuate or provided with 2–4 rounded lobes on each side, sometimes linear and expanding at the tip into an oblong or rounded blade; of mature plants 1½–3½ in. long, usually from ovate or oblong-ovate to ovate-lanceolate or elliptic-lanceolate, sometimes obovate, more rarely narrower and lanceolate or linear, acute, petiolate, coriaceous, deep shining green above, paler beneath, veins transverse. Cymes large, many-flowered, 1½–4 in. long, terminal and axillary. Flowers white, sweet-scented, ¼ in. long. Calyx-lobes about ⅓ as long as the corolla-tube. Corolla with a long tube often inflated below the throat; lobes much shorter than the tube. Anthers included within the corolla-tube. Capsule 3–6 in. long, terete, acute.—Hook. f. Fl. Nov. Zel. i. 181. P. albiflora, Raoul, Choix, 17. Hook. f. Handb. N.Z. Fl. 187. P. variabilis, Lindl. in Journ. Hort. Soc. v. (1850) 196. P. macrocarpa, Col. in Trans. N.Z. Inst. xiv. (1882) 331.
North and South Islands: Abundant from the Three Kings Islands and the North Cape to Foveaux Strait. Sea-level to 2500 ft. Kaiku; Kaiwhiria. November–March.
I have restored Cunningham's name for this species, it having at least five years' priority over that of Raoul.
2. P. capsularis, R. Br. in Mem. Wern. Soc. i. (1809) 65.—Habit of P. heterophylla, but smaller and more slender. Leaves equally variable, of young plants ¾–3 in. long, narrow-linear or lanceolate to spathulate, entire or sinuate or irregularly lobed; of adult plants varying from extremely narrow-linear, 1–4 in. long by sometimes barely 110 in. broad, to oblong or oblong-lanceolate, 1–2½ in. long by ½–¾ in. broad, obtuse or subacute, coriaceous; margins usually entire. Cymes few or many-flowered, axillary and terminal, usually shorter than the leaves. Flowers small, ⅛ in. long. Calyx-lobes equalling the corolla-tube or very little shorter. Corolla campanulate, tube short; lobes revolute, as long as the tube. Anthers exserted.—A. D.C. in D.C. Prodr. viii. 401 (in part); Raoul, Choix, 17; Hook. f. Fl. Nov. Zel. i. 180. P. rosea, Raoul, l.c. 16; Hook. f. l.c.; Handb. N.Z. Fl. 188. P. Forsteri, G. Don. Gen. Syst. iv. 79. P. ochracea, Col. in Trans. N.Z. Inst. xxii. (1890) 480. Periploca capsularis, Forst. Prodr. n. 126; A. Rich. Fl. Nouv. Zel. 205.
