alternate, 2-4 in. long including the petiole, $-1} in. broad, narrow elliptic- 
oblong, obtuse at both ends, but often unequally so at the base, thick and 
coriaceous, glabrous and finely reticulated above, beneath densely covered 
with smooth yellowish-white tomentum ; veins indistinct ; margins slightly 
recurved, even or very slightly undulate. Corymbs large, much branched, 
9-4in. diam., on long slender peduncles. Heads very numerous, in. 
long, broadly turbinate ; scales of the involucre in 3—4 series, the lowermost 
ovate, the upper elliptic-oblong, laxly tomentose. Florets 10-15. Achenes 
deeply grooved, clothed with spreading hairs. Pappus-hairs equal.

January. 
Although closely allied to O. furfuracea, this can be at once distinguished by the 
parallel-sided narrow elliptic-oblong leaves, which are equally rounded at both ends. 
The heads are also broader, and have more numerous florets than O. furfuracea. 
13. O. pachyphylla Cheesem. in Trans. N.Z. Inst. xln (1910) 216.— 
A much and closely branched shrub 4-8 ft. high; branches very stout, 
grooved and angled, the younger ones clothed -with appressed brownish 
tomentum. Leaves alternate; blade 3-5 in. long by 2-23 in. broad, ovate 
or oblong-ovate, obtuse or subacute, rounded and more or less unequal 
at the base, excessively thick and coriaceous, glabrous above, beneath 
clothed with densely appressed silvery-white or silvery-brown tomentum ; 
margins entire but more or less undulate; veins finely reticulated beneath, 
less evident above; petiole stout, grooved, 1-14in. long. Corymbs much 
branched, 3-5 in. diameter; peduncles 4-6 in. long. Heads very numercus, 
4-3 in. long, narrow at the base but gradually widening upwards; scales 
of the involucre in very many series, densely imbricated, the lowest minute, 
the upper gradually larger, thé whole more or less clothed with yellowish- 
brown woolly tomentum. Florets 7-10; ray-florets 3-5, disc-florets 4-6. 
Pappus-hairs unequal in size, rigid, thickened and fimbriate at the tips. 
Achenes striate, silky-pubescent. 
Nort Istanp: Bay of Plenty, hills and sea-cliffs at Opape, on the road from 
Opotiki to Torere and Te Kaha, Bishop Williams ! N. Potts ! March-April. 
A very remarkable plant. In habit and foliage it much resembles O. furfuracea, 
and when out of flower might easily be taken for a robust large-leaved form of that 
species. But the flower-heads are altogether unlike those of O. furfuracea, or of any 
other species, being remarkable for their great length (quite jin.) and the number of 
the involucral scales (35-45), which are imbricated in 6-8 series, thus giving the 
involucre an altogether different appearance from that of O. furfuracea. In that species 
the heads do not exceed 4in., and the scales number 12-15. 
14. O. Thomsoni Cheesem. n. sp.—A tall branching tree 8-15 ft. high ; 
branches stout, spreading, terete, glabrous or. nearly so; younger ones 
grooved and angled, faintly tomentose at the tips. Leaves alternate, 
rather large, 3-6in. long including the petiole, 13-2in. broad, oblong- 
obovate to elliptic-ovate, cbtuse or subacute, gradually tapering at the 
base into a moderately long petiole, coriaceous but not conspicuously so, 
entire or very obscurely sinuate, glabrous and very finely reticulate, beneath 
clothed with thin and very finely appressed silvery-white tomentum, veins 
finely reticulate, midrib evident. Corymbs large, much branched, open; 
peduncles long, glabrous; pedicels very slender, 4-4in. long. Heads 
very numerous, 4in. long, narrow-turbinate; scales of the involucre in
