Oi^DEE LXXIY. ASCLEPIADACEJE. Gen. PL ii. 728 



{Asclepiadece), 



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

 tions opposite, sometimes wanting, stipules 0. PL 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. Corolla-lobes valvate 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, filaments 

 in most genera connate into a stamina!- 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 staminalf 

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

 Ovary of 2 distinct carpels, ovules usually numerous, 2-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 copious albumen, radicle short, inferior. 



I. Filaments usually free, pollen-masses granular. Climbing shrubs, excepting Utleria, 

 A. Corolla-lobes contorted, overlapping to the right.
