from all other pedunculate species by the narrow ri^id foliage 

 and foliaceous bracts.

 fj. O. traillii, T. Kirk, Trans. N.Z. Inst., xvi. (1883), p. 372; 



Forest Flora of N.Z., t. 142. 



A shrub or small tree, 15ft. high or more, ^vith robust 

 tomentose branehlets. Leaves crowded near the tips of the 

 branchlets, 4in.-6in. long, lin.-ljin. broad, lanceolate or 

 narrow obovate-lanceolate, acute or acuminate, narrowed into 

 a broad winged petiole, very coriaceous, white beneath, 

 margins doubly crenate with narrow rounded callous points. 

 Heads in erect terminal 3-8-flowered racemes, with foliaceous 

 deciduous bracts ; rhachis, peduncles, and under-surface of 

 bracts white with appressed tomentum ; peduncles 2in.-8in. 

 long ; involucral leaves in 3 series, scarious, acute, the outer 

 sparingly tomentose at the tips ; ray-florets ligulate, disc- 

 florets tubular campanulate. Achenes grooved, silky. 



Hah. Sea-level, Stewart Island, rare and local. 



One of the most striking plants in the N.Z. flora, easily 

 distinguished from the other racemose species by its narrow 

 leaves and rayed heads. Eays milk-wbite, disc-florets violet- 

 purple. 



6. O. colensoi, Hook, f., Fl. N.Z., 115, t. 29. 



Ilab. North and South Islands to Stewart Island. Not 

 observed below 3,000ft. in the North Island, but descends to 

 sea-level on Stewart Island. Ascends to 5,000ft. 



In the North and South Islands this fine species is con- 

 fined to the mountains, and is usually a bush or shrub with 

 leaves varying from broadly-oblong to narrow-obovate, but on 

 Stew^art Island it descends to the sea-level, and occasionally 

 developes into a tree 40ft. high, with a trunk 2ft. in diameter. 

 The under-surface of the leaves, and the peduncles, are clothed 

 with white appressed hairs, the flower-heads are destitute of 

 rays, and the florets are of e lurid brown colour, approaching 

 black. The leaves are usually crenate or doubly crenate, but 

 occasionally specimens are found in which the margins are 

 doubly serrate, both primary and secondary teeth being ex- 

 tremely acute.

tica, Hook, f., Fl. Antarct., ii., 543. 



A shrub or small tree, sometimes nearly 30ft. high, with 

 trunk 2ft. in diameter ; branches open, robust, tomentose. 

 Leaves broadly-ovate or orbicular-ovate, abruptly acuminate, 

 excessively rigid and coriaceous, doubly serrate or crenate, 

 wdiite with floccose tomentum above, and with appressed
