Remarks on the Kaieteur Savannah. 241 
peared to me distinct by their difference in habit, but 
which at Kew they regard as inseparable. AuBLET figured 
one of them in his Plantes de la Guiane, but only one 
European herbarium contained a specimen previous to 
my expedition. 
In the broken woodland over the left arm of the precipice 
which extends from the fall, there grows one of the best 
Guiana plants, regarded from a floral point of view. It is a 
shrub or small tree belonging to Rubiacece, named 
Isertia hypoleuca, Benth., with beautiful soft scarlet 
ixora-like flowers, produced in wonderful masses, and 
great abundance. Few cultivated plants could rival its 
effectiveness. From this position, looking down into the 
valley below the Kaieteur, the white bloom of Fer- 
dinandia rudgioides, Willd, was everywhere observable, 
on what appeared shrubs a few feet high. I found later 
that these were in reality trees of a considerable 
size. 
Melastomaceze, in number of species, are not plentiful in 
this flora. Only three were in bloom, and but one of these 
occurred commonly. This is scattered over the open face 
of the savannah and charms one with its beautiful foliage and 
flowers. These characters and its dwarf habit make it a 
desirable subject either for garden or stove cultivation. In 
the less open parts, and less plentifully, Comolia surinamen- 
sis, Miq., is found. C. microphylla, with proportionately 
large flowers, is a pretty little rock plant only a few inches 
hig;h. Among the shrubs which in situations more favorable 
to growth would attain the size of small trees is a 
Swartzia deserving of notice for its attractive yellow 
flowers, as does also Cyrilla antillana, with copious
