| The staminate capitulum of Elatostema coriaceifolium W.T.Wang is discovered and described for the first time. The corrected description of the staminate capitulum of E. prunifolium W.T.Wang,and the corrected diagnosis of E. medogense W.T.Wang var. oblongum W.T.Wang are given. The taxonomic revisions of E. nasutum Hook.f. and E. nanchuanense W.T.Wang are made,including two new varieties,E. nasutum var. ecorniculatum W.T.Wang and E. nanchuancise var. scleroceras W.T.Wang,and two new ranks,E.nasutum var. yui(W.T.Wang)W.T.Wang and E. nanchuanense var. calciferum(W.T.Wang)W.T.Wang. One species belonging to sect. Weddellia(H.Schröter)W.T.Wang,E. apicicrassum W.T.Wang,and three species belonging to sect. Elatoatema,E. latitepalum W.T.Wang,E. pseudonasutum W.T.Wang and E. oxyodontum W.T.Wang,are described as new. E. medogense var. oblongum W.T.Wang and E. quiquecostatum W.T.Wang,relegated to synonymies several years ago,are restored here. |
