of unisexual and hermaphrodite flowers may be effected 

 during different periods. There is also a tendency for the 

 hermaphrodite and unisexual flowers to occcur in separate 

 clusters, 'though the mixed condition in the same inflor- 

 escence has been noticed (see pi. XI., fig. 4-6). The flowers 

 are strongly aromatic, and Mr. Willis informs me that they 

 are visited by many bees at Peradeniya. 



Male inflorescence arises on lower part of young shoots 

 in axil of caducous bract or foliage leaf ; when the latter the 

 clusters are more crowded and abundant. The bud is 

 enclosed in a sheathing bract ; two small bracteoles appear 

 on the primary peduncle at right angles to the antero-posterior 

 axis, and in the axil of each a flower appears. Each lateral 

 flower becomes the median flower of another cyme, and this is 

 repeated until we have a crowded dichasial cymose inflo- 

 rescence of 7, 15, or more flowers on a peduncle only 7-10 

 mm. in length. The first pair of lateral flowers have pedicels 

 over 2 mm. in length, but the subsequent flowers are 

 subsessile along their respective axes ; bract subtending 

 inflorescence green, hairy, caducous, 6-10 mm. long ; the 

 bracteoles are much smaller, green, hairy, caducous ; flowers 

 in April, fruits September-February. The inflorescence 

 attains a length of 20 mm. and is similar to the male of D. 

 Ebenum and D. Toposia. (See pi. XI., fig. 1-2.) 



The flowers are small, white, fragrant and openly bell- 

 shaped. 



Calyx green, total height 3 mm. ; segments 3-4, pubescent 

 or ciliate, rounded apex, accrescent, 1 mm. long. 



Corolla white, urceolate or campanulate, total height 8 

 mm., diameter at top 8 mm. ; segments 3-4, rotate, glabrous, 

 rounded apex, 3 mm. long. 



Stamens irregular, 13-22, epipetalous, single or united in 

 2's or 3's forming usually about 8-10 groups ; when in pairs 

 the shorter anther is innermost (cf. D. Gardneri) ; anthers 

 yellow, introrse, shortly apiculate, dehiscing laterally from 

 apex ; filaments white, united or separate, glabrous except 

 near base of anther.
