2 Materials for a Flora of the Malayan Feninsula. 



rarely solitary or fascicled, regular, hermaplirodite. Calyx-tuhe nnited 

 by vertical walls to the ovary, rarely nearly free ; limb usually 4-5- 

 ( sometimes 3- or 6-)lobed, or truncate, rarely falling off in a cap. 

 Petals as many as the calyx-lobes, contorted in bud, inserted on tbe 

 margin of the calyx-limb. Stamens as many as or more than (frequently 

 twice as many as) the petals, inserted with them ; alternate stamens 

 often shorter, sometimes rudimentary, filaments bent inwards in the 

 bud ; anthers opening at the summit by one or two pores, rarely by vslits 

 down the face ; connective often appendaged near the base by bristles, 

 tubercles or a spur. Ovary 4-5- (rarely 3- or 6-) celled (in Memecylon 

 1-celled) ; style simple, filiform, rarely short ; ovules very many (except 

 in Memecylon) ; placentas axile, parietal or free central. Fruit included 

 in the calyx-tube, capsular or berried, breaking up irregularly or by 

 slits through the top of its cells. Seeds minute, very many (in 

 Memecylon one only) ; albumen ; cotyledons short (or in some of the 

 Memecylem long, thin and convolute).— Distrib. Species about 2700, 

 tropical, with a few subtropical ; mostly in America, but many in south- 

 east Asia, and a few in Africa and Polynesia.
