I don't know if this is due weather differences, but the photos you posted and the description do not appear to be that of the Philippine Lacatan that I grew up with. There are three varietal sources of Lacatan in the Philippines: Cavite, Davao, and common. I listed that in order of mature p-stem height. Cavite the shortest and the common the tallest. Cavite and Davao fruits are slightly shorter, but their diameters are the same as the common. There are no difference in taste. Once the fruits are cut from the p-stem, there is no way of really telling apart.
