mentioned various shrubs Ilex Macoucoua, Pers 
[No. 75], Dipteryx reticulata, Beth [No. 73], Myrcia 
Roraimse Oliv, N. sp. [No. 74] and M, Kegelianae Berg 
aff [No. 82]), which in places fringe the banks of 
this stream and are also characteristic of the upper, 
proper, flora of the mountain. Along the banks of this 
river, too, after its emergence from the mountain, grows, 
in the peaty soil at the water's edge, a very beautiful and 
sweet scented white orchid, Aqanisia alba, Ridley N. sp. 
[No. 360] and, on the more rocky parts of the bank a 
very remarkable red passion flower [No. 84] with 
panicles of many pendent flowers, each panicle having 
the appearance, the facies, to use that ugly but con- 
venient term again, of a spray of fuchsia blossom. * It 
was here too, in the deep cuttings made by the river 
and half filled up with huge blocks of stone which are 
now overgrown with gnarled trees and shrubs, that one 
of the most famous of all Roraima plants grows — 
Cattleya Lawrenceana Rch. fil. N. sp. [No. 80]. 
This Cattleya is doubtless the one collected by the 
SCHOMBURGK brothers, and enumerated by RICHARD 
SCHOMBURGK, as C. pumila ; for it appears to be the 
only representative of this genus occurring on this side, 
at least of Roraima ; and this was the only side visited 
by the ScHOMBURGKS. It grows, apparently not hi^h up 
on the mountain, but on the gnarled tree trunks, close 
to the water, in the clefts through which the Kookenaam 
and some of its small tributary streams flow, at a height 
of about 3700 to 4000 feet above the sea. At the time of 
* This passion flower is well figured in the Schomburgk drawings of 
which mention has already been made.
