Angolan native. This is a rare tree, shown here at Fullerton Arboretum (Fullerton, California, USA). It may well be the only specimen in the USA. It sets pods regularly, but seeds fail to mature properly. I have considered grafting this on the locally-plentiful C. leptophylla.
Is it grown in India? http://i192.photobucket.com/albums/z93/fastfeat/Cas_ang1-1.jpg http://i192.photobucket.com/albums/z93/fastfeat/Cas_ang3.jpg Regards-- Ken.
