58 TlMEHRI, 
which I was previously unacquainted. Here too Astro- 
carium gynacanthum was prevalent, and one spadex of 
its fruit was obtained. In the forest above Kalacoon 
some plants of Dalebanna (Geonoma sp.) — and Booba 
Iriartea exorhiza were observed, but they were 
not plentiful, and two or three clumps of Awarra (Astro- 
carium tucumoides), or a closely related species, were 
passed on the banks of the river. 
From this Indian settlement we proceeded to the First 
Falls, as the first rapids on the river are called. Here 
we made a camp and remained for two days. The soli- 
tude and animated river and forest scenery make the 
locality very charming. Again, the banks which appa- 
rently closely shut the river in are not the shores of the 
river, but of the first of the many islands which, beginning 
at this point, form a long series, breaking the water for 
miles. In the open streams, reefs of rocks appear, against 
which [the current surges, chafing and foaming over the 
top ; and sandbanks, crisp as snow to the tread, line the 
shore. We went up the rapids as far as time would per- 
mit, and examined the woods and shores en route. A 
mile or so above our camp a woodcutter's benab was seen 
— a large building appearing not to have been recently 
occupied. During the first day at Kalacoon so many plants 
new to me were found in flower that I expected the num- 
ber of new forms to become less day by day as 
most have an extensive diffusion within certain limits, 
and are met with over and over again, and our journey 
would not extend far enough for a very considerable 
change of subjects to be anticipated. But day after day 
there was no diminution in the number of novelties.
