Kirx.— Botany of Great Barrier Island. 91 
or two or three together; capsules small, globose, downy, 2-valved; valves 
2-lobed, granulated on both surfaces. 
Allied to P. colensoi by the globose capsule and short peduncle, which 
are, however, terminal and pubescent ; differing in all other respects. 
Pittosporum [n.s.?] kirkii, Hf, n.s.—A handsome, laxly-branched 
shrub, 8 to 15 feet high, without flower or fruit, but differing widely in habit 
and foliage from any deseribed New Zealand species of this genus, was 
observed at an altitude of 1,600 to 1,800 feet; branchlets stout, bark red- 
purple, leaves alternate or whorled, crowded, ascending, narrow, linear- 
obovate, acute or obtuse, 2 to 5 inches long, gradually narrowed into 
rather broad purple petioles, excessively coriaceous, pale green on both 
_ surfaces, glabrous, with mid-rib stout, and prominent beneath. 
Pittosporum crassifolium, Banks and Sol.—This is a common tree on the 
coast, with invariably terminal, solitary, deewrved peduncles ; and very large 
fruit with somewhat concave valves. I have seen no other form north of 
Auckland, except on the Little Barrier Island, where a spreading bush with 
terminal, umbellate, erect peduncles, appears to be confined to a solitary 
habitat. This plant bears exposure well, and is worthy of a place in every 
shrubbery. 
Pittosporum umbellatum, Banks and Sol, var.?—A small tree, which in 
the absence of flowers may be referred to this species, is found in the 
northern part of the island, and may be readily distinguished by its narrow 
leaves, which are sharply tapered downwards, and by the truly cordate 
capsules, the valves of which are not lobed. The capsules of P. wmbellatum 
have the valves excessively lobed, and produced so as to give a square outline 
with concave sides. 
Lepidium [P] oleraceum, var.—A. much-branched plant, 1 to 2 feet 
high, branches and root stock stout, leaves 1 to 2 inches long, narrowed into 
petioles, fleshy, linear-spathulate, deeply incised at the tips. Flowers 
numerous, tetrandrous, pods ovate, cordate, keeled at the back, and finely 
reticulate. 
Leptospermum ericoides, A. Rich, var. pubescens.—A prostrate or sub- 
erect shrub, sometimes 3 feet high, at others appressed to the rock, like 
an alpine plant; leaves more or less pubescent and ciliated; flowers fra- 
grant, produced in immense profusion, sometimes concealing the leaves ; 
pedicels and calyx downy. This would make a valuable bedding plant for 
the culturist. It was originally observed on the island by the late Dr. 
Sinclair, but I am not aware of its occurrence elsewhere. 
Metrosideros ^ ?— A striking plant belonging to this genus, but with- 
out flower or fruit, occurs in the central parts of the island, usually a small 
bush, not exceeding 20 feet in height, with straight ascending branches, and
