116 REPORT ON THE PLANTS 
the latter much shorter and broader : the ovarium is sericeous, crowned 
by three reflexed pointed stigmata. It appears that in both the male 
and female plants, the branches soon lose their leaves, or probably do 
not renew them on the second year, when the bare axils, at about four 
inches apart, throw out their racemes of flowers.

axillis nodosis, foliis late ellipticis basi cuneatis apice repente at- 
tenuatis mucronatis margine reflexis glaberrimis subtus pallidis 
5-nerviis, nervibus 3 prominulis rubescentibus, lateralibus tenuibus 
fere marginalibus et mox evanidis, venis transversis conspicuis et 
anastomosantibus, petiolo canalieulato apice basique valde inerassato

Near A. Sellowianum, but with larger and broader leaves, which are 
not só thick and coriaceous, and with shorter petioles; the racemes 
are not pubescent, as in that species. The leaves are here,5 inches 
long, 24 inches broad, with a petiole 14 inch long; the racemes are 
2 inches in length.
