A rather large tree with erect trunk and wide-spreading 

 head, bark rather smooth, grey, young parts glabrous ; 1. on 

 very short petioles, 3I-4I in., obovate-oval, tapering to base, 

 rounded or very bluntly acuminate at apex, entire or obscurely 

 serrulate at top, margin somewhat revolute, glabrous and 

 somewhat shining on both sides, very dark dull green above, 

 pale and with obscure glandular dots beneath, rather thick, 

 veins inconspicuous, stip. large, f in., interpetiolar, enclosing 

 terminal bud, caducous ; fl. small, sessile, few, in small heads, 

 on stout branches of axillary trichotomous cymes much 

 shorter than 1.; cal. glabrous, segm. 7 or 8, lanceolate, acute; 

 pet. small, 7 or 8, clawed, roundish, coarsely undulate-dentate 

 at margin ; stam. twice as many as pet., scarcely longer than 

 cal.; style stout; fruit small, about \ in., berry-like, smooth, 

 red ; seed with thick orange testa, tabulate. 



Moist low country ; rather common. Fl. Feb.; creamy- white. 



Also in India, Burma, Malaya, China, and Trop. Australia. 



Heart-wood very hard, pale orange-coloured, tough, shining, with 

 conspicuous medullary rays, not durable. A gum exudes from the fl.-buds 

 and glues the fl. together in the heads. This tree very obviously shows 

 its relationship to the mangroves by the large tufts of aerial roots it 

 sends forth from the trunk and branches : these are admirably seen in 

 many of the old wild trees in Victoria Park, Colombo. 



The leaves show on their under surface a line or fold at some distance 

 on either side of the midrib precisely similar to those in Erythroxylon 

 Coca and due to the same cause, the mode of packing in the bud.

A large tree, with thin rough grey bark, 1. on very short 

 petioles, 3-3' in., broadly oval, tapering at base, shortly 

 acuminate and twisted at apex, entire, glabrous, stiff, bright 

 green, gland-dotted beneath, lat. veins numerous, parallel, 

 conspicuous; fl. few, nearly ] in., on stout ped., in scanty erect 

 dichotomous axillary cymes half as long as 1., bracts rounded 

 mucronatc, caducous; cal. glabrous, segm. 4, acute, as long as 

 tube, pet. 4, clawed, incised-fimbriate; stam. 8; fruit about ^-in., 

 pyriform, crowned with erect connivent cal. -segm., red, 

 glabrous.
