4 ser. xvii. 47 ; — foliis paulo latioribus, supra in nervis sul- 
catis tonientellis, apice niucronatis non cuspidatis. — v.s. (? et $ 
San Gabriel, Rio Negro (Spruce, 2340). 
Internodes 1-3 inches ; leaves 3^-3| inches long, 2-2| inches 
broad ; petiole 14-18 lines in diam.; racemes $ 3-4 inches long; 
pedicels 1 line; flower, in bud, ^ line in diam.; incrassated 
pedicels, in fruit, 2 lines long ; drupes not quite matured, 9 lines 
long, 5 lines broad, compressed. 
8. Abuta rigida, nob. ; — ramulis teretibus, fusco-tomentosis ; 
foliis oblongis, imo rotundatis, apice acutis et cuspidato- 
mucronatis, rigide coriaceis, fuscis, utrinque glaberrimis, 
supra nitentibus, subtus opacioribus, e basi 3-nerviis, cum 
nervo altero in margine mox evanido, supra in nervis sul- 
catis, subtus nervis venisque transversis immersis vix promi- 
nulis ; petiolo subtomentoso, imo apiceque incrassato, limbi 
quarta vel quinta parte longitudinis ; paniculis racemosis, 2-3, 
fasciculatis, supra-axillaribus, dense griseo tomentosis, petiolo 
2-3-plo longioribus ; rarais brevibus ; floribus minutis, bre- 
vissime pedicellatis ; pedicellis imo bracteolatis. — In prov.Para 
Brasilise, v. s., Barra do Rio Negro (Spruce). 
The entire glabrous leaves and their semi-immersed nerves 
give to the plant much the appearance of an Anelasma; but the 
tomentose stems and petioles, the pubescent and stouter racemes, 
indicate, without further examination, that it is a species of 
Abuta ; and this is proved by the structure of the flowers. The 
branches are 1^ line in diam., the internodes l|-3 inches; 
the leaves 4^-6;^ inches long, 2|-3^ inches broad ; the petiole 
:|-1| inch long, the panicular racemes l|-3 inches long, the 
branches 1| line long, the pedicels ^ line long, the flower in 
bud ^ line in diam. 
Species presumed, but unknown to me. 
9. Abutal oblongifolia •, — Cocculus oblongifolius, (nonDC.) 
Flor. xxiv. Beibl. ii. 43; Walp. Rep. ii. 748; — subvolubilis, 
ramis, petiolis floribusque dense aui’eo vel fulvo tomentosis ; 
foliis coriaceis, oblongo-ellipticis, basi cordato-rotundatis, 
apice brevi acutiusculo, obscure 3-5-nerviis, junioribus subtus 
(praesertim in nervo) fulvo toraentellis; racemis $ brevibus, 
simplicibus ; drupis lineari-ellipticis, 8-9 lin. longis. — In Rio 
de Janeiro. 
From its general character, and more especially the size and 
shape of its fi-uit, there can be little doubt that this plant is a 
species of Abuta, certainly not a Cocculus. It approaches the 
last species in its semi-immersed nervures.
