Remarks on the Kaieteur Savannah. 243 
Among the plants which are the pioneers of the forest 
in its steady encroachment on the savannah there are 
two that, by their predominance, play a principal part, 
which I must briefly notice before I quit the review of 
the arboreal part of the vegetation. They are Bonnetia 
sessilis and Archytoca triflora, highly characteristic 
trees. Along the skirt of the forest where it slopes from 
the fully developed members within, through younger 
growth, to the open ground, these form the bulk of the 
vegetation. From the quality of their bloom, too, they 
are both plants meriting particular attention. The white 
floral leaves and bracts under the pink flowers of 
A rchytoca make it a singular and conspicuous object 
everywhere, particularly where it is most abundant 
and the associated trees appear massed together for 
effect. The red bloom of Bonnetia, if less effective at a 
distance, when seen within a few yards is more beauti- 
ful still. 
Turning now to the large variety of herbaceous vege- 
ation which grows intermingled, to a large degree, 
with the foregoing plants, under the conditions required 
or attainable by each, there is found much to afford in- 
terest and pleasure to the investigator. Wandering 
through thickets of the great Brocchinia I was puzzled 
to observe tall lax panicles of, what appeared at a dis- 
tance, pea-formed flowers, rising three or four feet and 
spreading from among its leaves. These proved to be 
the flowering stems of an aquatic plant subsisting in the 
water contained in the axils of the leaves of the 
Brocchinia, which, like some other Bromeliacea?, con- 
serves in the pockets formed of the bases of
