Castanella riparia and a yellow-flowered Bauhinia (Schnella) were 
also seen ; but the vegetation on the whole is miserably monotonous 
and Amazonian. 
April 17th. On the ground in some places there are beds of a 
delicate Gesnera with white flowers, in habit like a larger-leaved 
Chrysosplenium. Sometimes on the edge of banks only a few inches 
above the water there is a beautiful fringe of Gymnogramme 
calomelanos, po 
April 22nd. A Davilla (Dilleniaceae) on the margins is just 
opening its sulphur-yellow, odoriferous flowers. Of trees with tall 
clear trunks, often white with rudimentary lichens, is a fig with 
lanceolate leaves ; an Acacioid tree with largish bipinnate leaves 
and numerous fine leaflets—habit of a Dimorpbandra or a Pen- 
taclethra. 
2nd.  Ochroma sp. (Malvaceae) with deeply cordate 
leaves is frequent on inundated shores, with Cecropia peltata, and 
is one of the trees most frequently encountered fallen in the water 
(as the river goes un drying) from banks giving way. 
A curious Rubiaceous twiner with large leaves like those of a 
Nonatelia, large interpetiolar stipules, and largish yellowish flowers 
like those of a Cinchona. 
here were two species of Ruyschia (Marcgraviaceae) ; one very 
frequent has long branchlets with closely-set, almost linear leaves, 
and were it not for terminal umbels of red berries might almost be 
taken for a fern (Pleopeltis) as it hangs from trees. 
ery frequent in woods is Paullinia, with dense clusters of 
flowers on the naked sulcate stem, surely same as from Coary—

trifid, some entire, very acute at base, and copious yellow flowers ;

Notes at Andoas.— Rainy weather, sore feet, the cares of engaging 
oarsmen and of procuring food for the voyage, left me small leisure 
for botany. 
The last day of my stay I had a walk into the forest, which was 
cut short by the coming on of a heavy thunderstorm, and I returned 
nities! Comme un canard. The track was very muddy as I went, 
ri as I returned it was a little river with occasional lakelets. 
noted another arborescent Alsophila, with subpilose fronds.
