these characters may be absent in such flowers, or may be 
occasionally present in male flowers. 
The development and anatomy of the seedlings was origi¬ 
nally studied from seeds obtained from the polygamous 
trees. 
The male and hermaphrodite flowers occur separately or as 
members of the same axillary inflorescence ( cf . D. sylvatica 
and D. Ebenum). 
Male inflorescence consists of sessile and subsessile pubes¬ 
cent cymes ; developmentally it first appears as a red 
pubescent bud in the axil of a leaf with or without a peduncle; 
on either side at right angles to the antero-posterior axis a 
bract appears, each subsequently bearing a flower in its axil. 
After a long interval another pair of opposite bracts appear 
in a plane at right angles to the first, followed by a flower in 
the axil of each. The primary flower occupying the centre 
of the inflorescence may be subsessile or supported on a 
peduncle 10 mm. in length, but each subsequent flower is 
always sessile. Further complications follow in consequence 
of the development of pairs of flowers around each of the 
subsequent flowers mentioned above. Peduncle 1-2-10 mm. 
long, green, pubescent ; bracts small, 2*5 mm. long, 2 mm. 
wide, caducous, tapering apex, pubescent. (See pi. XII., 
tig. 5.) 
Calyx green, ventral surface pubescent, 5 mm. long ; 
segments 4, 3 mm. long, accrescent, deltoid, acuminate apex, 
straight or slightly recurved margin. 
Corolla yellow, conical in bud, 10-13 mm. long, tube 
inflated ; segments 4, half the length of tube, spreading, 
glabrous inside, silky pubescence outside. 
Stamens 12-16, epipetalous or monadelphous hypogynous 
group, separate or connate in pairs, inner series always 
shorter than outer ; when 12 only they are usually as 4 pairs 
and 4 singles, the former being divisible into an outer and 
inner series ; anthers inner series 3 mm. long, apiculate,
