MOUNT RORAIMA IN BRITISH GUIANA, 41 
shorter than the florets, with imbricating bracts in 10 or 12 series, the innermost about 
14 in. long, 12-33 lin. broad, strap-shaped to lanceolate-oblong, obtuse, the outer 
gradually smaller, ovate, obtuse, tomentose on the back. Receptacle with a few 
deciduous bracts, scattered among the florets, about 1} in. long, linear, obtuse, sparsely 
and minutely denticulate-ciliate. Corolla glabrous, with a tube about 4 in. long, 
‘slightly enlarging upwards, and spirally revolute linear-acute lobes, about 8 lin. long, 
i-$ lin. broad. Anthers about 7 lin. long, with the tails connate in pairs. Ovary 1 in. 
long, compressed, glabrous. Style much exserted, minutely bifid at the apex. Pappus- 
bristles copious, unequal, the longest about 10 lin. long, minutely adpressed pubescent, 
dull straw-coloured, or pale tawny. 
Summit of Mount Roraima, 8600 ft., McConnell & Quelch, 661. 
A very distinct species, readily distinguished by its large heads, and the very long 
exserted styles. It appears to be a connecting link between Stifftia and Wunderlichia. 
The presence of bracts upon the receptacle and the minutely bifid stigma, technically 
place it in the genus Wunderlichia, Riedel, but the plant has a different appearance, 
and the receptacular bracts are not persistent and not of the same character or scarious 
texture as those of Wunderlichia, In all probability when more species are discovered 
it will be found that the two genera will have to be united.

Apparently a shrub, densely tomentose on the youngest parts of the shoots. Leaves 
alternate, coriaceous, petiolate; petiole 2-6 lin. long, tomentose in the young state 
becoming glabrous; blade 1-21 in. long, 5-10 lin. broad, obovate or oblong-oblanceolate, 
obtuse or more or less apiculate, cuneate-acute at the base, entire, at first with a thin 
tomentum on both sides, which soon disappears and the leaf becomes glabrous; midrib 
impressed and pubescent above, very prominent beneath, veins reticulated, impressed 
above, scarcely prominent beneath.  Corymbs pedunculate, small, hemispherical or 
subglobose, very densely many-headed, {-1 in. diam.  Peduncles 3-1} in. long,
