226 Materials for a Flora of the Malayan Peninsula. 



in. in diam,, buds globose. Calyx with 4 obtuse lobes. Petals 4i, 

 obovate. Stamens 8 ; the anthers oblong-ovoid ; filaments free, short, 

 subulate. Ovary ovoid, sessile, 2-celled. Berry globose when ripe, 

 glabrous, "6 to "8 in. in diam. Hook. fil. Fl. Br. Ind. I, 513. Sclera- 

 stylis Boxhurghii, Wight, Ic. t. 72. Amyris simplicifolia, Roxb. Fl. Ind, 

 II, 244. 



Perak : common. Penang, Malacca ; Griffith (KewDistrib.) No. 537. 



There are in the Calcutta Herbarium a large number of fruiting 

 specimens of this from Perak ; but not a single one in flower. These 

 specimens agree so entirely with Roxburgh's figure of Amyris simplici- 

 folia in the Calcutta Herbarium (of vvliich Wight's Ic. 72 is a copy) 

 and with Griffith's Malacca specimen (No 537), that I have no hesitation 

 in referi-ing them to the same species. The description of the flowers 

 given above is copied from Sir Joseph Hooker's Fl. Br. Ind. I, 513. 



Order XXIV. SIMARUBE^. 



Trees or shrubs, usually with bitter bark. Leaves alternate, often 

 large, pinnate or rarely simple ; stipules or deciduous. Inflorescence
