Palms of British Guiana. 223 
tions of the various tribes and sub-tribes, quoted from 
Sir Joseph Hooker, and definitions of the genera, 
quoted for the most part from GRIESBACH'S " Flora of 
the West Indies," have been inserted. Seventy spe- 
cies, belonging to twenty-one genera, are recorded from 
this district, though of these some few have 
possibly been included by mistake. Of these species 
the greater number are somewhat evenly, and in 
comparative abundance, distributed throughout the dis- 
trict. Some few, for instance Orbignia Sagotii, Trail 
and Astrocaryum plicatum, Drude, seem to be confined 
to one or two very limited spots. A few others, nearly 
all on the authority of RICHARD SCHOMBURGK, seem to 
be confined to certain remote districts of the colony, 
but to be there fairly abundant. SCHOMBURGK has, 
for the general purposes of his flora, distinguished 
the colony into four regions, thus : the coast region, 
now mostly cultivated and with many exotics mingled 
with its indigenous plants : the forest region : the 
sandstone region, almost entirely mountainous, and in- 
cluding the far-famed Roraima : and, the savannah 
region, rather undulating than mountainous, and for the 
most part granitic. Making use of this division into 
regions, in the following synopsis of the palms recorded 
from Guiana the apparent distribution of each species is 
indicated :

1 Euterpe oleracea, given on the authority of Schomburgk, seems to 
me perhaps identical with the one I have given as E- stenophylla, Trail.
