 connate, usually adnate to the base of the deciduous corolla ; anthers basi- 

 fixed or versatile, dehiscing by slits or rarely by terminal pores. Ovary free 

 (^-inferior in Anneslea), sessile, 3-5-celled, (many-celled in Actinidid) ; styles 

 as many, free or connate, stigmas usually small; ovules 2-co in each cell, 

 rarely solitary, never orthotropous. Fruit baccate or capsular. Seeds few 

 or numerous, placentas axile, albumen scanty or 0, rarely copious ; embryo 

 straight or hippocrepiform, cotyledons various. DISTRIB. Rare in tempe-
