Asclepiadoidae (Formerly Asclepiadaceae) (Milkweed Family)

There is a surprising number of species of milkweed, but our own is the largest and most ostentatious. As of January 2018, APG IV places Genus Asclepias in Order Gentainales, Family Apocynaceae, Subfamily Asclepiadoideae. I am retaining the name Asclepiadaceae for ease of access in the indices of this webiste.
