22. O. Haastii, Hook.f., Handbk. 126. A much-branched shrub, 5ft.- 

 8ft. high. Branches rather stout, hoary, as are the petioles and peduncles. 

 Leaves ^in.— lin. long, spreading, oblong-ovate or elliptical, obtuse, shortly 

 petioled, reticulate on both surfaces, shining above, white with appressed pubes- 

 cence below ; veins not forming a right angle with the midrib, rather obscure. 

 Peduncles slender, naked, exceeding the leaves. Corymbs lax or compact. 

 Heads numerous, ^in.— |^in. long, sessile and fascicled or on short pedicels ; 

 involucre subcylindrical ; upper involucral bracts linear-oblong, obtuse, ciliate, 

 slightly pubescent or nearly glabrous. Rays 3—4, short. Disk-florets 4—5 ; 

 mouth very short, abruptly contracted into the tube ; segments spreading or 

 recurved. Achene ribbed, pubescent. 



SOUTH Island : near the glacier of Lake Ohau, 4,000ft. to 5,000ft., Haast I 



The spreading habit of this shrub and its short broad obtuse leaves contrast strongly with the 

 characters of the next species. 



23. O. oleifolia, T. Kirk in Trans. N.Z.I, xi. (1878) 463. A much- 

 branched shrub, 5ft.— 8ft. high. Branchlets grooved, crowded, pubescent or 

 hoary, erect, slender. Leaves 2in.— Sin. long, J^in.— |in. wide, shortly petioled, 

 coriaceous, lanceolate or oblong-lanceolate, acute, erect, white with appressed 

 tomentum beneath, forming a smooth surface ; veins obscure. Peduncles twice 

 as long as the leaves. Heads on slender pedicels, numerous ; involucre 

 narrow, cylindrical; bracts narrow, linear-oblong, pubescent at the tips, the 

 inner almost membranous and nearly glabrous. Rays 2—3, obovate. Disk- 

 florets 2—3. Achenes furrowed, pubescent. — O. angustata, J. B. Armst. in 

 Trans. N.Z.I, xiii. 337.

This plant bears much the same relationship to 0. Haastii that 0. ilicifolia bears to 0. macro- 

 donta. It differs greatly in general appearance, but the floral differences are slight : the heads are 

 smaller and have fewer flowers ; the involucral bracts are narrower and more membranous ; while 

 forms with intermediate leaves occur, although but rarely. 



24. O. SUavis, Cheesem. in Trans. N.Z.I, xxiv. (1891) 409. A shrub or 

 small tree, 6ft.— 18ft. high, rarely prostrate, excessively branched. Branches 

 stout; branchlets slender, short, clothed with pale fulvous pubescence. Leaves 

 shortly petioled, oblong or narrow-oblong or ovoid, |in.— Hin. long, ^ in .—fin. 

 broad, entire, obtuse, rounded or almost cuneate at the base, subcoriaceous, 

 rarely undulate, brownish-yellow with laxly-appressed tomentum beneath ; veins 

 slender. Peduncles exceeding the leaves, very slender, much branched, tomen- 

 tose. Heads numerous, on rather long pedicels, ^in.-Ain. long; involucres 

 turbinate, narrow; bracts few, lax, the lower short, pubescent or villous, the 

 upper narrow-linear-lanceolate, acute, pubescent, and ciliate at the tips. Florets
