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 ? in.) and the number of 
the involucral scales (35-45), which are imbricated in 6-8 series, thus giving the 
involucre an altogether different appeagance from that of O. furfuracea. In that species 
the heads do not exceed $in., 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, 1-2in. 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, 4-4 in. long. Heads 
very numerous, 4in. long, narrow-turbinate; scales of the involucre in
