(Asclepiadece). 



Perennial herbs or shrubs, frequently climbing, 1. entire, with rare excep- 

 tions opposite, sometimes wanting, stipules 0. Fl. regular, bisexual, penta- 

 merous, usually middle-sized or small, inflorescence axillary or interpetiolar, 

 usually cymose. Calyx inferior, as a rule divided to the base, sepals imbricate 

 in bud. Condla-lobes valvafe or contorted in bud, usually overlapping to the 

 right. Stamens 5, inserted on the base of the corolla, anthers cohering or 

 connate, enclosing the stigma, usually with inflexed membranous tips, tilameuts 

 in most genera connate into a staminal-tube, the end of the style being as a rule 

 a broad pentagonal disk (style-table) with the stigmatic surface underneath. 

 Pollen-grains rarely free, in most genera united into waxy masses, one or two 

 in each anther-cell. The pollen-masses of the adjoining cells of two contiguous 

 anthers are attached in pairs or in fours to solid dark coloured bodies, the pollen- 

 carriers (corpuscles), which lie on the edge of the style-table. Corona either 

 corolline, inserted inside the corolla-tube between its lobes, or stamincti, 

 consisting of variously shaped appendages, attached to the back of the anthers. 

 i (vary of •_' distinct carpels, ovules usually numerous, "-'-seriate in each carpel. 

 Fr. of 2 follicles (or one by abortion), seeds compressed, usually winged and 

 surmounted by a dense brush of hairs (coma). Embryo large, cotyledons flat, 

 in CO pious albumen, radicle short, inferior.
