Abstract

Nephelium L. is a genus belonging to the family Sapindaceae that is widely distributed in the Southeast Asia region and Borneo is known to be the center of diversity of this genus. The study of Nephelium species distribution and flowering-fruiting pattern in Borneo is not much studied yet. Therefore, based on herbarium specimen collections in Naturalis Biodiversity Center (NL), the distribution and the flowering-fruiting pattern of 16 Nephelium species in Borneo were studied. Distribution maps were generated by ArcView GIS 3.3 software based on specimen’s longitude and latitude coordinates. Flowering and fruiting season pattern of each species was assessed based on the collection date of the specimens stated on the labels. From the distribution maps produced, it was found that each species has different distribution. Sarawak and Sabah recorded the most diverse Nephelium species. Nephelium maingayi, N. ramboutan-ake, and N. uncinatum were found to be the species with the widest distribution in Borneo and also recorded to be flowering and fruiting all year round. From this study, it shows that a distribution and flowering-fruiting pattern study of Nephelium species is possible to be done by using digital data from Naturalis Biodiversity Center. To support this study and supplement the information, a comparison with another herbaria is suggested.
