FORESTS OF THE UAUPES 335 
expert at hunting out fungi, which were tolerably numerous near 
Panure ; I got indeed so many species that they seem to me 
worth distributing, and I enclose along with the flowers two 
parcels of fungi (and two or three large species wrapped up 
separately) which I will thank you to forward to Mr. Berkeley, to 
whom I am writing at this time. 
I was rather disappointed with the Podostemese, though perhaps 
I ought not to have been. Very few species grow together in 
any one place, and the time they last is so short that it is 
impossible for one person to get many species. There are plenty 
of raudalitos (rapids) on the Casiquiari, Orinoco, and Cuna- 
cunuma, so that I may hope to get a good many species yet.

[The trunk of this tree is 4 feet thick and 80 feet high. It has racemes of 
rose-coloured papilionaceous flowers. It grew on the rocky banks of the 
cataracts.] 
I was at Panure at the best time of the year for everything but 
Ferns, and these seemed mostly the same as I had already got at 
Sao Gabriel. x\mong trees of the forest and caatinga I made a 
splendid harvest, and the species of Vochysiacese and Csesal- 
pinieae seem to me peculiarly interesting. You will be pleased to 
see two additional species of Aptandra, Miers, the first gathered in 
the gapo in flower and fruit, and the second in the caapoeras in 
fruit only. . . .

date, gives further details of his work on the
