Order LX. MEZiASTOZIIACES:. (By C. B. Clarke,) -'V 



Herbs or shrubs, more rarely trees, sometimes cHm'bers. Leaves opposite or rarely 

 whorled, generally petioled, entire or nearly so, often palmately 3-5-7-nerved from 

 near the base to tae apex (usually pinnate-veined in Meynecylon) ; stipules 0.. 

 Flowei's Bipk^A. panicled or corymbed, rarely solitary or clustered, tegular, herma- 

 phrodite. Calyx'tvbe united by vertical walls to the ovary, rarely nearly free v 

 limb usually 4-5- (sometimes 3- or 6-) lobed, sometimes truncate, rarely falling oit 

 in a cap. Petals as many as the calyx-loles, contorted in the bud, on the mar- 

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

 as) the petals, inserted with them ; alternate stamens often shorter sometmies 

 rudimentary, filaments bent inwards in the bud ; anthers o|)enin^ at the sxmmut 

 by one or two pores, rarely by slits down the face ; connective orten appenda^a* 

 near the base by bristles tubercles or a spur. Ovary 4-5- (rarely 3- or ^r 

 celled (in Metnecylon 1-celled) ; style simple, filiform, rarely short; ovules very 

 many (except in Meineeylon) ; placentas in the Melastome(B axUe, in the -^^^(^ 

 nieee parietaL in Metnecylon free central. Fruit included in the calyx-tube^ 

 capsular or "berried, bfreaking np irregularly or by slits through the ^V ^ r^ 

 cells. Seeds minute, very many (in Metnecylon one only); albumen 0; coty- 

 ledons short (or in some of the Memecyle<B\orMg thin convolute). — DlsTBlB. opf*
