Just wondering, could this be Hydnocarpus macrocarpus (Bedd.) Warb. (Achariaceae)? The species name is spelt as macrocarpa in some sources.
Yes, it is Hydnocarpus macrocarpus …, some of the fruits having the size of Couroupita guianensis fruit Cannonball. Sharing fruit image. Thank you very much for ID my tree.
1 image.
Thank you very much for your message. The fruit image is of an another individual and the same isn’t posted earlier of doubting.
Good population here, some with only fruits, some started to blooming but haven’t matured or immature fruits, some yet haven’t flowers neither fruits.
Here it is wet biome and growing not only in streamside, but seems everywhere. Rarely, some small trees also flowering, but number of flowers are very low.
There was a strange flower smelling in surroundings of the tree and fallen flower collected as specimen.
Your first set of close-ups is of the male flower with what appears to be a short, aborted pistil. Do look out for the female / bisexual flower with the lobed stigmas.
