Notes on Plants at Roraima. 173 
flowered Xyris setigera, Oliv., N. sp., [No. 62] is there. 
The small pink-flowered Begonia tovarensis Kl. [No. 141] 
is there. A very few plants of Brocchinia cordylinoides. 
Baker, just two or three single specimens, are there ; 
but of this too, I shall have more to say presently. 
Various ferns are there, especially the magnificent Cycad- 
like Lomaria Boryana. 
And many orchids are there ; a ' lady's slipper' 
Selenipedium Lindleyanum Reich, fl. [No. 53] with 
huge branched flower stems, each bearing many blooms, 
the whole plant, flower leaf and stem alike, all velvety in 
texture, and of various shades of one colour, the colour 
of sunlight as it falls through young green beech-leaves ; 
the beautiful Zygopetalum Burkei, * Reich, f. [No. 50], 
with flowers seeming like gigantic, pale coloured " bee 
orchises', (Ophrys apifera, Huds) but of far sweeter scent ; 
in great abundance the rosy flowered Pogonia parviflora 
Reich.fi. [No. 115], which recalls in habit our English 
wild tulip {Tulipa sylvestris) ; and, to mention but one 
more among many, Epidendrum elongatum, Jacq. 
[No. 42], its stems varying in height from one to eight 
feet, its verbena-like clusters of flowers varying in 
colour in different plants, some pale yellow, some fawn 
colour, many pure rich pink, dark purple and even 
mauve. This last mentioned orchid, it may be noted in 
passing, is one of a group to which I shall presently 
refer. 
The effe6t of the whole is of an Alpine meadow 
coloured in early summer by innumerable flowers of the 
brightest and most varied tints. 
* This is represented on the Organ mountain by Z. Mackaii.
