AROUND SAO GABRIEL 291 
Lecythis were very numerous, and I had not time either to 
gather or preserve all I saw. I hoped to get some of them here 
in fruit, but I cannot see a single Lecythis in the gap6 of the falls. 
The Leguminosae (^Diplotropis nitida and other varieties) were 
frequent nearly all the way up. . . . 
The Dicorynia Spruceana (a tree 80 feet high) was frequent 
and very ornamental from a little below Barcellos nearly to the 
base of the falls. About the falls its place is supplied by another 
Csesalpineous tree {Aldma latifolia\ which I gathered in flower 
and hope to get also with ripe fruit. 
Shortly after I reached here my montaria broke from its moor- 
ings one night and went over the falls. I sent my two men in 
quest of it. They were out all night, and returned next day with 
the montaria, which an honest Indian had found almost uninjured 
wedged between two rocks. They brought me also a branch of a 
tree in flower which proved to be a small-leaved Dicorynia. Three 
or four days afterwards I went down the falls to get more of it ; 
but the flowers were nearly all gone, and, strange to say, we could 
find only that one tree from which the men had plucked the 
branch. 
Gustavias were tolerably frequent, but it was scarcely possible 
to preserve their flowers on account of the number of caterpillars 
bred in them. 
It would surprise most people to be told that Proteaceae are so 
numerous on the shores of the Rio Negro (in individuals, not in 
species) as to give a marked character to the vegetation. I am 
acquainted with three or four Proteaceae (Andriapetala) of the 
terra firme, but I have never been able to find them in flower or 
fruit. All that I have hitherto gathered (including the one from 
Santarem) are of the gapo. All are remarkable for the leaves of 
the young plants being polymorphous — pinnate, pinnatifid, or 
iaciniated, though this is not noted by Endlicher under Andria- 
petalum. 
The finest tree on the Rio Negro is an apparently undescribed 
Bignoniacea. If the genus be new, I hope you will allow me to 
call it Henriquezia, in honour of Senhor Henrique Antonij, a 
native of Leghorn, but for more than thirty years settled at the 
Barra do Rio Negro, where he has constantly rendered every 
assistance to scientific and other travellers during that period, as 
you may see by referring to all the works that have been lately 
written respecting these rivers. 
Above Uanauaca all was rapids ; indeed, there 
had been Httle else from Sta. Isabel.
