Help locating this plant?

[Steve Klarer]

Can anyone help me in finding a source for Campylotropis macrocarpa? It's
also known as 
Lespedeza macrocarpa. (I personally know nothing about horticulture and am
just helping a friend who wants to locate this particular plant. We are
located in Massachusetts, USA, so sources in this country would be the
best.)

If it's possible I'd much appreciate email replys as it's sometimes
difficult for me to get into usenet. 

Thanks,
Steve Klarer
