Thanks for the resource, Dave! I like Oikos.
They posted this great groundnut quote:
“Digging one day for fishworms, I discovered the groundnut (Apios tuberosa) on its string, the potato of the aborigines, a sort of fabulous fruit, which had often since seen its crumpled red velvety blossom supported by the stems of
other plants without knowing it to be the same. Cultivation has well nigh exterminated it. It has a sweetish taste, much like that of a frostbitten potato, and I found it better boiled than roasted. The tuber seemed like a faint promise of Nature to rear her own children and feed them simply here at some future period. In these days of fatted cattle and waving grain - fields, this humble root, which was once the totem of an Indian tribe, is quite forgotten...” Walden by Henry David Thoreau
