Papua star-fruit (Averrhoa dolichocarpa Rugayah & Sunarti) and Gorontalo star fruit (A. leucopetala Rugayah & Sunarti), also known as belimbing hutan, are two wild species belong to the star fruit family (Oxalidaceae). Information about both species are very limited. The aim of this study is to document the fruits process from two wild Averrhoa species: A. dolichocarpa and A. leucopetala, and the impact of their environment such as edaphic factors. Research on the fruit Phenological observations of the two species was conducted through at Bogor Botanic Garden. It was started when the flower at the anthesis phase until the fruit was rippen. Observed factors included morphology and other external factors such as insects or animals. The result showed that differences in fruit development between the two species was the time they took to get their fruit ripen: fruit of A. dolichocarpa riped within 39 days after anthesis, while the fruit of A. leucopetala riped within 42 days after anthesis. The results of measurements of fruit length and weight during fruit formation showed similar patterns of development between the two types of forest starfruit observed. The length and weight measurement during the fruit development showed similar patterns. During the anthesis phase there were several insects visiting the flowers, such as Apis cerana, Amegilla sp., Xylocopa caerulea and Trigona sp. The Bogor Botanic Garden’s environment is still very good for the growth and breeding of both species, indicated by their high fruit production.
