They offered us ciruela fruits at coffee break this morning, here at the Centro de Formacion de la Cooperacion Española in Cartagena de Indias, Colombia. Deliciously tart, but I had no idea what it might be — botanically, I mean — which always annoys me. I asked around, and narrowed it down to a Spondias, probably Spondias mombin. Certainly looks like the photo here. The go-to source for information on tropical New World fruits is, of course, the database put together by my colleagues at Bioversity. In looking around for other photos, I came across a travel site called Dave’s Travel Corner which has a page on tropical fruits and a great photo gallery. Plus a whole bunch of links.
