forest, it is necessary to dip into it here and there 
and not trust alone to observations taken from the river. 
These corrections I endeavoured to add to my notes from 
time to time. 
Pursuing the journey from Portico creek, most of the 
common forest trees of the colony are observed. In 
some cases plants strike one by their absence or infre- 
quency compared with other similar districts, others by 
their plentifulness, but in general, allowing tor this 
variation, there is a very considerable unity between 
this and the river-side flora within the same belt of the 
rest of the colony. Bullet-tree occurs in more or less 
plenty throughout the whole region. Near the river, mora 
is in general the commonest tree. Dally and etaebally — 
Vochysia tetraphylla — appear here and there. The 
arisowroo — Vatairea guianensis — is exceedingly abun- 
dant all through the forest region, and as it was laden 
with its large fruit pods and void of foliage at the time, 
was probably the most noticeable of the forest trees. 
The large wild-plantain — Ravenala guianensis — is com- 
mon through much of the district as undergrowth in 
the wet forest. Two forms of cannaheriballi — Pachira — 
with large red flowers nearly or quite a foot long, make 
big trees 70 or 80 feet high, and are striking objects 
in bloom. In one, the flowers are ochre red through- 
out, while in the other the free filaments of the stamens 
are white. These replace the smaller and much more 
common cannaheri — P. aquatica — which is found on 
the Icooroowa and all the lower parts of the river. 
Simaruba is plentiful and grows to a considerable height 
and size. I measured one tree that would have squared 
twenty inches. In places in the upper region the forest
