Notes on Plants at Roraima. 223 
amongst mosses by Weir-frons 5-6 cm altus cum 
ramulis 1 cm. latus ramis remotiusculis bipinnatis 
ubique limbo pellucidiore cell. 4 lato margine denticu- 
latis divaricatis angustis subciliatis. All these species 
shew that in S. America there is a development of larger 
forms than are yet known elsewhere. 
Blipharozia Roraimae, Mitt. n. sp. folia ere6to-patentia 
imbricata cochleariformi concava integerrima lobulata ob- 
tusa ; involucralia conformia, prianthera (abortiva) cylin- 
dracea abrupte obtusissima ore parvo rotundo. From 
the top of Roraima ; one stem only. 
Entire plant of a dark red brown colour, about 4 cm. tall ; 
it is divided below into two, one being again forked, the 
leaves are imbricated in bifarious order and are repeatedly 
in interrupted series, each innovation arises from towards 
one side of the dorsal base of the perianth with small 
leaves which increase rapidly in size upwards, the largest 
being the involucral ; here the greatest diameter is about 
4 m.m. long, and of these as many as four are observable 
on the undivided stem ; and as each innovation arises from 
the same position they stand at the side of the stem rather 
towards the neutral ride. In all particulars they closely 
resemble the abortive perianths seen on B. sphagnoides and 
other species ; the young innovation also is in close simi- 
larity to that of the male amenta of that species, but there 
is no trace of the lobule, which is not, as has been sup- 
posed, distinct from the leaf in B. cochleariformis, but is 
seen from being an almost closed one in some species to 
be opened out in B. evoluta.
