New Genera of Plants from Bolivia.

(Pirates CLXVII.-CLXX.) 
MALPIGHIACE. 
Of Bentham and Hooker’s four tribes of Malpighiacee, my 
first genus differs from the first in its pyramidal torus; from the 
second in its non-climbing habit, and wingless fruits, combined 
with two-formed stamens and appendaged anthers ; from the third 
by its wingless fruits and two-formed anthers, and from the fourth 
by its 10 stamens, those alternate with the petals being the defec- 
tive ones. Its habit is certainly at agreement with the last tribe, 
and it would easily pass, without dissection, for a species of Cama- 
vea; but the androecium and general reproductive characters 
Separate it widely therefrom. All things considered it appears 
most closely related to the first tribe, where I place it, making an 
exception as to its gynobase, between the genera Acmanthera and 
Pterandra. 
BRITTONELLA. 
Caylx ample, foliaceous, somewhat accresent, deeply 5-parted, 
8-glandular, the glands ovoid and of medium size. Petals 5, on 
short claws, concave and incurved, the margins wavy and erose- 
dentate, in this species at least yellow. Stamens 10, sub-distinct, 
of 2 forms; those opposite the petals perfect, the filaments stout, 
dilated downward, glabrous, their anthers affixed at the outer base, 
partly deflexed, slightly winged at the base and appendaged with.
