Gynosciadion with one species, <i>Elatostema femineocymosum</i>, is chracterized by its numerous pistillate flowers in a 3-4 times branched cyme, lacking a receptacle with an involucre, and by these charactes can be distinguished from all other sctions of the genus <i>Elatostema</i>; (2) <i>E.gyronanophyllum</i> is closely related to <i>E.sinense</i> H.
