CONTEIBUTIONS TO BOTANY. 
this and the following species, similar to that which exists be- 
tween the two first-mentioned plants : the primary pair of basal 
nerves diverge from the midrib at an angle of 25° to 30° only, 
while the lateral nerves spring from the midrib much beyond 
the moiety of its length ; in A. macrophylla the nerves are more 
spreading. The leaves are 3^-8 inches long, 3-6 inches broad, 
on a petiole 2-4 inches long. The raceme-like panicles, on a 
somewhat flexuons rachis, are 6-10 inches long, with lateral 
branches, generally binate, 4-6 lines long, bearing at the apex, 
middle, and base an almost sessile agglomerated head of minute 
tomentose flowers. The fructiferous raceme is about 2| inches 
long, on a rather stout tomentose peduncle ; the pedicels, 2-6 
lines apart, are 3 lines long, stout, swollen at the apex, which 
bears three very tomentose ovately ohlong drupes, expanded 
into a thick excentric stipitate support ; they are 1-1^ inch long, 
somewhat compressed, 9 lines broad.

This species differs from the preceding in its much flatter 
leaves (of a darker green colour) being less coriaceous, with thin 
and scarcely revolute margins; the transverse nervures are 
scarcely channelled; they are also distinguished by their long 
cuspidate point at the apex, and more slender petioles. My 
specimens quite correspond with Guillemin’s : the primary pair 
of basal nerves diverge from the midrib at an angle of 35° to 40°, 
while the lateral nerves spring from the midrib below the moiety 
of its length, in which respect it differs from the preceding spe- 
cies, as before mentioned — a difference which is constant, what- 
ever may be the size of the leaves. In my specimens the leaves 
are 8 inches long, 6 inches broad, on a petiole 3^ inches long ; 
Guillemin^s are 5-7 inches long, 4^-6 inches broad, on a petiole 
of 2^-3^ inches. In Velloz’s drawing they are 9^ inches long, 
8| inches broad, on a petiole of 5| inches ; but they are said to 
be sometimes 13-14^ inches long and 13 inches broad. The
