I have found some semi wild Purple Air Potatoe/Dioscorea Bulbifera. its specs:
It has only green bulbifera leaves, small to big size air potatoes biggest is several pound, bulbils are smooth and rounded
Now the important part: The bulbils when raw are somewhat bitter and give intoxicating effect, BUT after boiling them they are NOT bitter. I ate a handful of the cooked and only feel a fraction of the intoxication caused by consuming 1/20 that amount of the raw.
In perspective in the past i encounter a bulbifera similar shape dont remember what exact colour, which after cooking was very very bitter and toxic the same as when it was raw.
So question :: are these to be considered edible or not.
By comparision of the two mentioned = this purple one is EDIBLE.
In a few threads people have said that when a edible air potatoes varieties end up in the wild, they turn bitter and toxic. Can anyone comment on that ? Can the reverse happen ie. a semi bitter variety in cared enviorment loose its bitterneess, and if yes then could anything help to speed/help that reversal??? I believe 100% that this specimen formerly a Edible type (or still is) or it would not have got to this island and be in the type of place where found it.
Please do not send PM for a bulb will, after confirming its edibility status - notify when put on ebay
