Notes on Plants at Roraima. 183 
intensely vivid crimson star-like flowers. This plant 
[No. 308.] Professor Oliver has identified as a Ledo- 
thamnus [No. 308], possibly L. guyanensis, Meissner, 
var. minor; but of much more slender form than is attri- 
buted to that plant in Martius Fl. Bras. VII. 172. 
Another shrublet, in character recalling the "Alpine 
Rose" {Rhododendron ferrugineum) bore even more 
disproportionately large flowers, of an exquisite pink 
colour. It was a Befaria, approaching B. resinosse, 
Mutis [No. 310]. Other tiny shrubs there were a white, 
feather-flowered Weinmannia ( W. glabra, L. f. var ?) [No. 
244], a myrtle [M. n. sp. aff. M. myricoidi, H.B.K. [No. 
1 89]) yetanother species of Psychotria, (P. im Thurniana, 
Oliver, n. sp. [No. 163]) ; a Baccharis (B. Vitis-Idsca, 
Oliver, n. sp. [No. 241]) ; and a Vaccinium (V. flori- 
bundum ? H.B.K. [No. 329]). On most of these tiny 
shrubs was growing an appropriately tiny mistletoe, 
{Phoradendron Roraimas, Oliver, N. sp. [No. 323],) a 
miniature of our English plant. Among all these, many 
other interesting plants occurred. There grew, in far 
greater luxuriance and size than below, the pitcher plant, 
Heliamphora nutans, Benth. [No. 257]. There grew 
great masses of two species of Xyris {X. Fontanisiana, 
Kth. and X. witsenoides, Oliver, N. sp. [No. 240],) 
the latter very striking and curious by reason of the 
Witsenia-like habit of their dark green-leaved stems, 
with pretty star-like yellow flowers. There grew a 
plant with a flower which, because of its form and colour, 
I at first sight mistook for a Frittilaria, like a 'snake's 
head,' (F. meleagris) ; but it was a new LisianihuSj 
which Professor Oliver has named L. im Thurnianus, 
Oliver, N. sp. [No. 306]. There grew many small, but
