Island, W. Travers (a very coriaceous-leaved variety, distinguished by F. 
Mueller as var. Chathamica) . Dr. Mueller is disposed to unite the New 
Zealand, Norfolk Island and Australian species, which are all very variable 
plants. 
Order V. PITTOSPOREJE. 
19- Pittosporum Colensoi. — For “leaves smaller” read “leaves larger.” 
19. 2 bis. Pittosporum Buchanani, Hook./., n. sp. A rambling-branched 
shrub, 10-12 ft. high; young shoots and leaves silky-pubescent. Leaves 
scattered, 2-5 in. long, of the male plant elliptic- oblong, acuminate, flat, quite 
entire, glabrous, of the female more oblong, shining green above, paler below. 
Peduncles axillary, solitary, slender, curved, silky-pubescent, -J-- J in. long, 1- 
rarely 2-flowered, the male usually longest, sometimes the peduncle is short 
and gives off 1 or 2 slender pedicels ; bracts at the base of the peduncle small, 
acute. Sepals obloug, obtuse. Petals linear, dark purple ; of the female 
smaller. Capsule as in P. tenuifolium.. 
Northern Island : from near Tongariro (cultivated at Wellington), Buchanan. 
It is with great reluctance that I add another Pittosporum to the series, already very diffi- 
cult of discrimination, that consists of tenuifolium , Colensoi , and fasciculatum. The present 
seems to be nearer to the last named species, but differs in the almost solitary flowers, slender 
silky peduncles, and obtuse oblong sepals. 
19- P. patulum. — Mr. Travers sends a fruiting specimen from the Upper 
Wairau, together with young foliage, which is linear, very narrow, and pin- 
natifid. 
20. P. rigidum. — Acheron Island, Dusky Bay, Hector and Buchanan. 
21. P. umbellatum. — Peduncles sometimes only in. long. 
Order VI. CARY OPH YLLEiE. 
22. Gypsophila tubulosa, appears to be rapidly spreading over New Zea- 
land, and is, doubtless, an imported plant. 
Stellaria gracilenta. — “ Leaf-margin not revolute ” {Knight), but I 
find it always much thickened or revolute to the midrib in the common form 
of the plant. 
25. Colob an thus Billardieri.- — Chatham Island, W. Travers. Distin- 
guished as a variety by F. Mueller, on account of the short pedicels and 
rigid channelled leaves. 
25. C. acieularis. — Hurumui mountains, Travers . 
25. Spergularia rubra, var. marina. — This is a rather large flowered state 
of the plant ; common in S. America, S. Africa, and Australia. 
Order IX. HYPERICINEiE. 
29. Hypericum gramineum. — Colenso considers this to be a rare and 
local plant, but I have specimens from very distant localities (Auckland, Wai- 
pura river, and Akaroa).
