This is described as a short tree with lax branches ; the axils 
are about 1| inch apart; the leaves are 5^ inches long and 
2 inches wide, upon a petiole 3 lines in length. The indores- 
cence is about f inch long ; the pedicels, which are capillary in 
flower, become thickened in fruit, especially towards their sum- 
mit, and are upwards of an inch in length ; the antheriferous 
tube, which I have represented in the drawing, exactly resembles 
that of the preceding species. The fruit is described in a pre- 
ceding page.
