Simpoh Air also known as Dillenia Suffruticosa. I like the bloom though this is ...almost wilted it shows the inner beauty of a green liked ball shaped plant. Some regard this as a tropical weed.The large leaves of the Simpoh air were used to wrap food such as tempeh (fermented soyabean cakes), or formed into shallow cones to contain traditional "fast food" such as rojak.
