A moderate-sized or large tree, evergreen, dioecious and 

 polygamous; branches glabrous, young twigs pubescent ; bark 

 black, thick, when freshly cut yellowish-red. Leaves very 

 variable in size and form, alternate, 75-180 mm. long. 25-55 

 mm. wide, oblong or oval -lanceolate, acuminate apex, 

 narrowed at base, glabrous and shining, thinly coriaceous, 

 deep green above, paler green beneath, venation reticulate. 

 pellucid, bullate, lateral veins prominent beneath ; petiole 

 7-25 mm. long, slightly p.ubescent below. 



The peduncle is usually curved so as to bring the flowers 

 directed downwards, in which case they are partially pro- 

 tected from sun, wind, and rain by the leaves. 



Sex. Some trees are male only, others female only, and 

 others polygamous ; several of the latter group are 

 growing at Peradeniya. 



The polygamous condition may be observed on many trees 

 growing at Peradeniya, and haa been determined for three 

 years in succession ; the flowers on polygamous trees may be 

 grouped as follows : (a) those with short accrescent calyx 

 segments, fertile anthers, and abortive apiculate pistil ; 

 (&) those with large deltoid calyx segments, margins of 

 which are straight or recurved, fertile anthers, and abortive 

 apiculate pistil ; (c) those with large deltoid calyx segments 

 with deep intersegmental grooves, fertile anthers, and fertile 

 pistil producing seeds. Hence the series from male to 

 hermaphrodite flowers on the same tree is gradual and com- 

 plete. (See pi. XII., figs. 1-8.) 



The accessory whorls exhibit very few external characters 

 which enable qne to distinguish the male from hermaphro- 

 dite flowers. The enlarged recurved calyx segments are 

 the best external indications of a hermaphrodite flower, but
