Rubiaceae, No ID
I photographed this fruit on an island off the Pacific coast of Panama. The fruit looks similar to Randia formosa. I tried to ID it with the Panama flora books I have. The closest thing I could find was Alibertia edulis, also called Trompito, Madroño, Zumbo, Guayabito de monte. I’d be interested to get a postive ID on this species.
