A newly naturalized genus and species, Sidastrum paniculatum (L.) Fryxell (Malvoideae Burnett, Malvaceae), native to the New World Tropics, was found in Qiaotou District, Kaohsiung City, southern Taiwan. The genus Sidastrum Baker f. is closely related to the genus Sida L., and its schizocarp has only one seed per mericarp. The genus Sidastrum can be differentiated from the genus Sida by its calyx without ribs and relatively fragile mericarps. A detailed morphological description and photographs of this newly naturalized species have been provided to facilitate identification.
