abundance as to redden the ground — the pretty little 
sundew, (Drosera communis [313]). Groups of very 
luxuriant pitcher-plants (Heliamphord) were there also. 
Great quantities of tiny shrubs of Alpine character, inter- 
wove their branches with each other and with the mosses. 
Among these were Weinmannia guyanensis, Kl. [327], 
Marcetia juniperina, D.C. [No. 319], Psychotria 
concinna, Oliver N. sp. Baccharis [No. 241]. Ledo- 
thamnus [No. 308], Be f aria [No. 310], Vaccinium [Nos # 
329, 326], Pernettya [No. 333 ex parte], and Gaultheria 
[No. 332J. The small Epidendrums, as on the ledge, 
were here too, as was the tiny mistletoe {Phoradendron 
[No. 323], and the fritillary-Iike Lisianthus [No. 306]. 
A beautiful Tofieldia (T. Schomburgkiana, Oliver, N. 
sp. [297]) and, somewhat similar, Nietneria corymbosa, 
[298], with large yellow flowers were conspicuous. 
In the crevices of the rocks the vegetation was 
different. There was a very beautiful Utricularia (U. 
montana, Jacq. aff. [No. 293],) larger and deeper in 
colour, but slightly less graceful than U. Catnpbellianum. 
And there were three species of ferns. One of these 
latter was a very stunted form of Lindsay a stricla, 
Dry., [No. 301], which in its ordinary form is common 
in many parts of Guiana. The other two were absolutely 
new — one a Hymenophyllum which Mr. Baker has 
named H. dejeclum, Baker, N. sp. [No. 318], the other a 
Gymnogramme, G. cyclophylla, Baker, N. sp. [No. 295] 
a second species of the same group of this genus to 
which belongs G. elaphoglossoides, Baker, N. sp. [No. 
101,215], found on the lower slopes of Roraima. Only 
one other species of this very distinct group is known, 
and has been found in the Amazon vallev-
