Hi all. I'm on a root crop kick at the moment, and am now working my way through the leguminous ones. I'm not looking for every obscure species just yet, but there are a few hard-to-find ones that I'd like to get my hands on now. I'm currently growing Winged Bean (Psophocarpus tetragonolobus), and I have a source for American Groundnuts (Apios Americana). As for what I want...
I'm looking for seeds of the African Yam Bean (Sphenostylis stenocarpa). Similar to Pachyrhizus, it has crunchy tubers, but unlike its relatives, it allegedly has edible leaves and seeds. It's apparently a variable species, with different landraces having different traits in their roots and seeds; I'd like to obtain several, if possible. Link:
https://www.nap.edu/read/11763/chapter/20#328I have Jícama seeds (Pachyrhizus erosus) so I'm not looking for it, but I am looking for two relatives: Ahipa (P. ahipa) and Goitenyo (P. tuberosus). Ahipa appeals to me for its short non-vining growth, and the fact that it's adaptable. Like Jícama, it has toxic seeds and leaves (Rotenone). Goitenyo appeals even more to me, and is a higher priority (as well as seeming harder to find) because like Sphenostylis, it allegedly has edible leaves and seeds.
If anyone has any of these three, I'd like to buy them. And better yet, if they have direct experience with them and can confirm the edibility of seeds & foliage of Sphenostylis and Goitenyo, that would be appreciated.
