Here's Calotropis procera, or roostertree, as I found it when visiting (back in 2005) the island of St. John.
|Calotropis procera (roostertree)|
As a member of the milkweed family (Asclepiadaceae), it reminds me of the many Asclepias species (which are in the same family) one will see along roadsides and in fields across much of North America in the summer time.

|Asclepias tuberosa, with Lysimachia nummularia (moneywort) 'Aurea' running around underneath.|
