Remarks on the Kaieteur Savannah. 237 
hood-shaped, lapping over each other so rigidly that, at 
the flowering period, instead of separating with the pres- 
sure of the developing flower stem, they are pierced 
right through by it ; so that if a plant in this condition 
be cut through at the base, they hang on the stem like 
so many fish threaded on a stick to be smoked or dried. 
These three plants, associated as they are by intimate 
alliance, form together, though in very unequal degrees, 
one of the chief of those features the combination of 
which gives that individuality which I have characterised 
as striking and interesting in this savannah flora. 
A remarkable feature of this flora, which strikes the 
observer very early, is the free combination within 
so limited an area of marsh and dry-land subjects, some 
of which submit to both conditions indifferently and 
thrive equally well under either. The large Brocchinia, 
to mention the most conspicuous example, is of the 
latter class. It is found under the widest extremes of 
conditions as to soil and moisture, and all the interme- 
diate modifications which these conditions present. In 
the soft aqueous ground which in wet weather is flooded, 
in the apparently impoverished water-washed gravel, 
and on the bare sun-heated rock it abounds alike plenti- 
fully. It cannot of course be said of this region, that 
plants which adhere to naked rocks live without mois- 
ture, as the daily recurring mists and frequent rains 
supply this. 
Of plants the least plastic in their habits, and which 
here confine their range to the dry ground, the numerous 
species of Clusia form, if not a predominant, at least a 
singular feature. Their variety is so great that their
