Wettinta Maynensis (Palmae) is now very frequent and grows 
occasionally close by the margin, along with the Iriarteas, from 
which it is distinguished at sight by the pinnae being equidistant 
and all spreading out from the rachis horizontally, but pendulous 
(from their weight) towards the apex, so that the entire-frond has a 
widely channeled form. In the Iriarteas the laciniae of the pinnae 
are in fascicles, the uppermost of each fascicle standing out above 
the rachis, the lowest pendulous, the rest at intermediate angles, 
¢ spadix very constantly 5-branched. 
Ma This day saw an Orchid in a tree for the first time 
since entering the Pastasa. It was an Epidendrum with corymbs 
of vermilion flowers, very like that from the falls of Aripecuru. 
Chimbillas disappeared just within the mouth of the Bombonasa, 
but the Pithecolobium is more frequent than on the Pastasa. Two 
broad-leaved Ingas seen on the Marajion and Pastasa are still not 
unfrequent. Bamboos, Gynerium, and Cecropias still grow in 
suitable places, as do also the Mulatto-tree and Ama-Sisa (Eryth- 
rina amasisa), 
e Chapaja and Biroti-wasi palms have given place to Wettinia 
Maynenis, Triartea ventricosa and Oenocarpus Bataua. The Rio 
Negro Euterpe is not unfrequent. 
In pursuing the Pinche a large animal fell from a projecting 
branch a little ahead of us with a loud crash and then darted off 
like an arrow. It was a tiger [jaguar], doubtless awaiting till some 
prey should pass beneath. did not even see it, but the Indian 
who was a few steps in advance did, and the marks of its broad 
feet were plain enough on the ground. We followed its track a 
short distance, but it had made clear off. 
and in this respect quite resembles the Calliandra of the Huallaga ; 
but the branches are much more flexible, and not long and wand- 
like, as in the latter. . 
Below the Calliandra on an inundated face of rock is a broad 
bank of a small, almost stemless, Carludovica (Cyelanthaceae), the 
pendulous shining-green fronds bipartite, the segments so narrow, 
and at so small an angle to each other, that until closely looked at 
one would take the plant for a grass. It is very like the Yacu- 
isa of Tarapoto. Underneath the Carludovica grow ferns and 
mosses down to the water’s edge, with here and there a Pyrat 
shrub. Of these shrubs the chief are a small Myrsinea ae & very 
narrow-leaved Myrcia (Myrtaceae), both ap arently identical with 
species at the Pongo of the Huallaga. There is also a pair 
leaved Rubiacea, resembling a Huallaga species, but different.
