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., 

 fig. 5.) 



Calyx green, ventral surface pubescent, o 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 monadelphons hypogynou* 

 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 ; anther* inner series 3 mm. long, apicniate.
