This is probably Shorea curtisii, Dipterocarpaceae, as it has three wings and the size of the mature fruit (centre) seems right. It fruits every 5-10 years after severe drought. The last masting event for Singapore was thought to be 6 years ago. The fruits littered the forest floor. BTNR, 20 June 2005.

Ixonanthes reticulata
Originally uploaded by lekowala.

20 June 2005. BTNR Ixonanthes reticulata Erythroxylaceae. Ten men is the english vernacular given to the tree which gives this fruit (a capsule). Malay name is Inggi burong, Nyiran burong or Pagar anak. Using Corner’s Wayside trees, I keyed it down to I. reticulata. The other species is I. icosandra. Parts of the capsule still green, have been dropping from the treetops; perhaps the birds are getting at the seeds hence the malay vernacular. The persistent sepals and petals are resinous sticky as described by Corner (1998).
