CONTRIBUTIONS TO BOTANY. 
with which and with some others it has been associated by Mr. 
Bentham and Dr. Eichler : it differs in its shorter, more oval, 
less acuminated leaves, rounded (not attenuated) at base, in its 
shorter petiole, and in its terminal, simple (not axillary and 
fasciculated), stouter raceme, with more simple and less filiform 
branches. The axils are 1 inch apart ; the leaves are 2|-3 
inches long, Ij-li inch broad, on a petiole ^ inch long: the 
terminal raceme is 4-5 inches long, its lateral branches 3 lines 
apart, 3—4 lines long, each bearing from three to six one-flowered 
pedicels ^ line long, bracteolated at base ; the flowers are very 
minute, their parts all conformable with the generic character.

This species differs from all the preceding in its more lanceo- 
late leaves, very acute at base, with shorter petioles, in its more 
lax panicle,- with filiform rachis, and almost capillary dichoto- 
mously divided branchlets, all which are extremely glabrous, 
excepting the bractlets ; the sepals and bracts are quite glabrous; 
the petals auriculately lobed on the sides, the lobes being invo- 
luted. The axils of the branch are 1 inch apart ; the leaves are 
4-4^ inches long. If inch broad, on a petiole ^ inch long; the 
extremely slender rachis of the panicle is 21-3 inches long, its 
branches 1-1^ inch long.
