Fishtail Palm

Hello. It is really important to provide images of plants that cover all or most parts of the plant. There are many palm species that produce the "mop-like cluster" type of inflorescence/infructescence (flowering/fruiting structure) shown in your spotting here. For the suggested species (the genus part I mean), Caryota, the fishtail palm, is known because of the shape of its leaves. So really an image of the leaves would probably be necessary to confidently identify your spotting. (Can you add a photo of the leaves of this plant?). If it is a fishtail palm, it is most likely to be Caryota mitis http://www.naturia.per.sg/buloh/plants/palm_fishtail.htm and not Caryota urens, which is not listed for Singapore in A Checklist of the Total Vascular Plant Flora of Singapore: Native, Naturalised and Cultivated Species by K. Y. Chong, H. T. W. Tan and R. T. Corlett available at http://rmbr.nus.edu.sg/raffles_museum_pub/flora_of_singapore_tc.pdf
