t. 59, f. 7A small tree 15-30 ft. in height, with a slender trunk and dark 
almost black bark ; young leaves and branchlets usually pubescent, becom- 
ing glabrous when mature. Leaves alternate, 1-24in. long, oblong-ovate 
or elliptic-obovate, obtuse acute or shortly acuminate, quite entire, mem- 
branous or slightly coriaceous, margins undulate ; petiole short. lowers 
axillary, solitary or fascicled, }-4in. long; peduncles about as long as the 
calyx, pubescent, straight or curved. Sepals oblong to ovate, obtuse or 
subacute, silky or glabrous. Petals dark-purple. Ovary silky. Capsule 
din. diam., 3-valved, broadly obovoid or subglobose, downy when young, 
glabrous and minutely rugose when old; valves rather thin.—A. Cunn.

An abundant and variable plant, the best distinguishing characters of which are 
the small submembranous leaves with waved margins, axillary and usually solitary 
flowers, and small capsules with rather thin valves. The leaves are often pale-green, 
especially on young plants. The species is often used for garden hedges or breakwinds, 
for which it is eminently suitable. 
2. P. Colensoi Hook. f. Fl. Nov. Zel. i (1853) 22.—-A small tree, very 
closely allied to the preceding, but larger and more robust, with stouter 
branches. Leaves 2-4 in. long, oblong-lanceolate elliptic-oblong or obovate- 
oblong, acute, coriaceous, margins usually flat ; petiole short, stout. Flowers 
axillary and solitary, rarely fascicled ; peduncles short, erect or decurved, 
glabrous or pubescent ; bracts not so caducous as in P. tenuifoluum. Sepals 
broadly oblong, glabrous or pubescent. Capsule globose ; valves thick and 
woody.—Handb. N.Z. Fl. (1864) 19; Cheesem. Man. N.Z. Fl. (1906) 58.

NortH AND SoutH Istanps, STEWART IsLAND: From Rotorua and the Patetere 
Plateau southwards, but often local. Ascends to 3500 ft. October—November. 
Very closely allied to P. tenuifolium, and connected with it by numerous inter- 
mediates. Mr. Kirk unites the two, and there is much to be said in favour of such a 
course. But it must be admitted that P. Colensoi, with its stouter branches, much 
larger sharply pointed and more coriaceous deeper-green flat leaves, has a very distinct 
aspect from P. tenuifolium ; so that, notwithstanding the intermediates, | am inclined 
to regard the differences between the usual states of the two plants as being too pro- 
nounced for varietal distinction alone, and I think that Kirk’s P. Huttonianum var. 
viridifolium is simply a large-leaved form of P. Colensot.
