The Asclepias Curassavica, cultivated in our gardens by the name 



of Possimuni (vulgarised from Apocyuum, under which genus all the 



AscIepiade:E and Apocyne:^ were arranged by the old botanists), 



forms an intermediate species between the A. laurifolia and A. pau* 



percula, having leaves strictly lanceolate, more thin and delicate in 



their structure than these plants, and flowers more brilliant 



Grows around pine barren ponds, and in damp, sandy soils. 

 Flowers May— July.
