1. P. tenuifolium, Banks and Sol. in Gaert. Fruct. i. 286, t. 59, /. 7. A 

 shrub or small tree, 20ft.— 40ft. high, with black bark. Leaves and twigs mostly 

 pubescent when young. Leaves liu.— Sin. long, pale beneath, shortly petioled, 

 lanceolate oblong or elliptic-obovate, obtuse, acute or acuminate, often undu- 

 late, submembranous or coriaceous. Flowers pedunculate, axillary, solitary or 

 rarely fascicled. Ovary silky. Capsule downy when young, 3-valved, glabrous 

 and minutely rugose when mature. 



An extremely variable plant, of which the chief forms pass so gradually into each other that 

 it is impossible to draw sharp lines of distinction. 



Var. tenuifolium, verum. Branohlets very slender. Leaves lin.-ljin. long, lanceolate, 

 oblong or ellipticj obovate, submembranous, ofcen undulate ; petioles slender. Flowers solitary. 

 Peduncles straight, about as long as the calyx, usually pubescent. Sepals ovate, oblong, or almost 

 subulate, obtuse or rarely acute, silky. Capsule broadly obovoid, valves rather thin. — DC., Prod. i.

 PI. Nov.-Zel. 306, t. 84, bis. NORTH and SOUTH Islands : common. Ascends to 3,000ffc. Oct., 

 Nov. Very variable in the form of leaves and sepals. The leaves are remarkable for their pale-green 

 colour, especially in the young state. 



Var. colensoi, T. Kirk in Trans. N.Z.I, iv. (1871) 262. Larger and more robust than tenui- 

 folium. Branchlets stouter. Leaves ljin.-3in, long, coriaceous, often waved, lanceolate, broadly 

 oblong-lanceolate, more acute, rarely obtuse. Peduncles very short, usually deourved, glabrous or 

 pubescent, the scarious bracts often persistent. Sepals usually oblong, glabrous or pubescent. Cap- 

 sule more globose, and valves much thicker ; inner reticulations stronger. — P. Colensoi, Hook, f., PI. 

 N.Z. i. 22, and Handbk. 19. NORTH and SOUTH Islands; STEWART Island: from the Bast 

 Cape southward. Ascends to 3,500ft. The larger-leaved forms are most frequent in the South. 



Var. fascioulatum, T. Kirk in Trans. N.Z.I, iv. (1871) 262. Habit of Colensoi. Leaves 

 usually elliptic-oblong or elliptic-obovate, acute or rarely obtuse, coriaceous. Flowers in terminal or 

 lateral fascicles or solitary. Peduncles usually short, glabrate or silky. Sepals ovate or oblong, 

 silky or tomentose, obtuse or acute. Valves of capsules very stout. — Sp. Hook, f., Handbk. 20. 

 NORTH and SOUTH Islands : from Rotorua to Preservation Inlet, but often local. 



Sub-var. cymosum. Leaves oblong-obovate or elliptio-obovate, subacute, more membranous. 

 Flowers in terminal cymes. Pedicels longer. Sepals longer, lanceolate-subulate, tomentose. Cap- 

 sule not seen. NORTH Island : Anaura, East Cape (with large leaves) ; Takeke, Waikare (leaves 

 small). Bishop Williams I 



2. P. Buchanani, Hook. /., Handbk. 725. A shrub, 8ft.-13ft. high, 

 with slender spreading or ascending branches ; glabrous except the young shoots 

 and leaves, which are silky-pubescent. Leaves scattered, spreading, submem- 

 branous, elliptic-oblong or lanceolate or broadly oblong, 2in.-5in. long, 

 iin.— l2iii- broad, acuminate or acute, flat; petioles slender. Flowers axillary, 

 solitary, perfect or unisexual, often polygamous. Peduncles very slender, 

 ascending, usually solitary, glabrous or silky-pubescent, 1- rarely 2-flowered; 

 bracts small, acute. Sepals ovate-oblong, acute or obtuse. Petals linear, with
