Flower of Petai (Parkia speciosa), family Fabaceae

"Parkia speciosa" is a plant of the genus "Parkia" in the family Fabaceae. It bears long, flat edible beans with bright green seeds the size and shape of plump almonds which have a rather peculiar smell, similar to, but stronger than that of the shiitake mushroom, due to sulfur-containing compounds also found in shiitake, truffles and cabbage.
