338 NOTES OF A BOTANIST 
The Lingoa Geral name is Cumandu-assu or Great Kidney bean, 
cumandil being a general name for seeds of every species of 
bean. 
In ascending the falls of Sao Gabriel I saw, but was unable to 
gather, two very interesting twiners occurring in some abundance. 
They are represented but sparingly on the Uaupes. One is an 
Apocynea with large bright yellow flowers, and the other is a 
Menispermea {Anomospermum Schombiirgkii^ Miers), interesting 
from the structure of its flowers and from their having a strong 
odour of mellow ribstons or golden pippins. Alas, that it should 
be " odor et praeterea nulla " ! 
Two Clusiacea were very frequent, both with odoriferous 
flowers, and looking very much alike though distinct. The larger 
one has flowers of four yellowish petals opposite the sepals, and 
the smaller one five white petals with four sepals, along with 
somewhat less coriaceous leaves. 
A fine Caesalpineous tree seems an undescribed Tachigalia, 
with silky leaves and very dense terminal racemes of yellow 
odoriferous flowers, the calyx being tinged externally with purple. 
The most remarkable feature is that at the apex of the petiole is 
a trigono-fusiform sac which is constantly inhabited by a colony 
of ants which pour out of a small hole bored underneath the sac 
to attack the hands of the too-eager botanist. 
Very frequent was a Humirium, attaining sometimes 40 feet 
or more, with a diameter of 4 feet and a very bushy mode of 
growth. . . . 
Melastomacese at present in flower included only two or three 
Tococas and a pretty Memecylea with very small shining leaves 
and yellow odoriferous flowers. Among the Myrtaceae I saw 
nothing that looked very new, and these, like Lauraceae, I was 
obliged mostly to forswear. 
A very ornamental tree, an Anonacea {Xylopia Spruceana^ 
Bth.), grew some 25 feet high, and its pinnate branches and 
small dark-green, crowded, distichous leaves gave it a very pretty 
cedar- like appearance. It grows also on the Casiquiari and 
Guainia. 
The caatingas around Jauarite caxoeira are of the loftier 
sort. Their vegetation has much general similarity to that of 
Panure, but it is less rich. There is a large Byttneriaceous tree 
{Myrodta brevifolia, sp. n.) frequent, which I have not seen at 
Panure. 
In the forest, especially near the Paapun's, grows a very lofty 
Vochysiaceous tree with pale yellow flowers. Another tree of the 
same family {Qualea acuminata, S., sp. n.), with large white 
odoriferous flowers, is frequent in the gap6. The shores of the 
Paapun's are peculiarly rich. . . .
