black and yellow flowered Odontoglossum (O. nigres- 
cens ?) and an Epidendron (near E. imatophyllum) 
with flowers curiously various in colour, mauve or rose 
to white and from yellow to fawn, many ferns from the 
low creeping kinds to the tall bracken {Pteris aquilind) 
and, yet taller, various species of tree ferns; and, 
though this is not abundant in that position, there also 
grows, most striking and suggestive of all to the Eng- 
lishman who has been long in the tropics, a real black- 
berry {Rubus Schomburgkii) very similar to the hedge 
brambles at home. And again, very sparingly on the 
higher open parts of this savannah swamp, but more 
abundantly and luxurantly inside the small coppices 
which break its extent, stands the remarkable aloe- 
like Brocchinia (B. cordylinoides, Baker), which, oc- 
curring there in very far greater abundance and luxuri- 
ance, forms the chief physionomic vegetation of the 
Kaieteur savannah. And again on the edges of the cop- 
pices of the savannah slope and on the edges of the for- 
est in the midst of which this lies, are many other striking 
plants, a peculiar climbing bamboo, tree ferns of several 
species, especially a great Cycas-like fern, thick stemmed 
with ere6l dark green fronds (Lomaria Schomburgkii), and 
among these, wonderfully luxuriant examples, with flower- 
ing stems of seven and eight feet high, of the various 
coloured Epidendron which has already been mentioned 
as growing, with far dwarfer habit, on the dry rocks of 
the savannah. It is no wonder that SCHOMBURGK was 
enthusiastic about such a place as this.*
