Swartzia polita (R.S.Cowan) Torke

March 21, 2010

It’s that time of the year again when every morning I find several arillate seeds of Swartzia polita on the floor of my house, dropped by bats having free access to it at night, and thus no doubt about the dispersal method for this species may arise. When the ripe fruit opens, its arrilate seeds hang on still attached to the seed box, in full display for picking by the nocturnal bats going after its nutritious arils (see the same bats, caught mating http://www.youtube.com/watch?v=YUJ258rOSu8).

Ants feeding on the aril:

More of my images of the species are on Flickr (http://www.flickr.com/photos/plants_of_russian_in_brazil/2993438004/in/set-72157594574369082/).
