Funny, I just ran into Swartzias for the first time today, and a search revealed this thread which I'd already seen but somehow never noticed before!
Swarzias are fascinating-looking plants:
The wood is amazing too.
Most seem to be considered medicinal, too, and they're nitrogen fixers.
I searched your species (Swartzia langsdorffii) and found very little about it (PFAF doesn't know it's edible). I found one page selling seeds - it translated to:
Also called MANIPOYBA, Chicken Lick, Monkey Pacová, White Jacaranda and Banana Pau. The pulp cooked in a little water and lightly sweetened is with taste that resembles a mixture of "papaya with orange". The tree is of
magnificent beauty, it provides good shade, it is still melífera and very ornamental with, beautiful flowers. R $ 49
What's your experience with it? I also found another Swartzia species that PFAF says is edible (Swartzia simplex), but again, very little about it.
Manny of these are edible just that they are undocumented and the trees got rare ,manny endangered or extinct.
The wood looks like rosewoods to wich they are related thogh its not that high quality as rosewoods.
The wood is compared to the non related Ebony( diospyros) but its a mistake because the egyptians used to call ebony a rosewood( d melanoxillon) not a diospyros.
Its sad that Schwartzias will have the same fate of the rosewoods and that we will not even get to know their wonderfull looking fruits.
Because the trees become rare,the new generations of the indigenous people that ate them will not have the chance to use these fruits and thousands of years of knowledge from their tribes about these fruits will be lost thanks to logging.
