Theferns is generally pretty decent obviously there will always be some problems but it does cite its sources of info and the page bangkok posted does have a citation for the male female comment. If thats a good reference or not i dont know i could never grow this plant where i am lol

Description
An online resource that is still being developed, it gives detailed botanical descriptions of plants in the family Euphorbiaceae found growing in Malesia (the region from Peninsual Malaysia through Indonesia, the Philippines)."
But I find the ferns to be a superb resource that has info you cant find anywhere else.
Im sure it must be the largest and most user friendly database on tropical edibles anywhere on the web, well in english at least.
If someone knows of a better or more comprehensive resource than Theferns I would really really love to know it!!!!
