| 1 | Weda,a new genus with two new species of Euphorbiaceae-Crotonoideae from Halmahera(North Maluku,Indonesia)and phylogenetic relationships of the Australasian tribe Ricinocarpeae显示文摘During the environmental impact study for a proposed nickel mine near Weda Bay on Halmahera in North Moluccas(Maluku Utara Province),Indonesia,two unknown Euphorbiaceae were discovered.Morphological comparisons and molecular phylogenetic analyses using four markers(plastid trnL-F and rbcL,and nuclear ribosomal internal transcribed spacer and external transcribed spacer)indicated that they should be recognized as constituting a new,distinct genus of two species,which are described and illustrated here as Weda fragarioides and Weda lutea.The new taxa are members of the Australasian tribe Ricinocarpeae in subfamily Crotonoideae,and they are most closely related to Alphandia.In contrast with the otherwise mostly sclerophyllous Ricinocarpeae,Weda possesses stellate to dendritic hairs,large,long-petiolate,glandular leaves,and inflorescences with a pair of large,leafy,subopposite bracts.The two narrowly distributed species are distinguished from each other by vegetative and floral features,molecular data,and elevational preferences.Leaf elemental analysis of Weda indicated manganese,but not nickel,accumulation.Newly resolved generic relationships and potential morphological synapomorphies within Crotonoideae are discussed,and the circumscription of Ricinocarpeae is expanded from 7 to 11 genera. | Peter Cvan Welzen Susana Arias Guerrero Deby Arifiani Tjut J.F.Bangun Roderick W.Bouman Marcel C.M.Eurlings Iska Gushilman Peter B.Phillipson Iris Tabak Esmee Winkel Kenneth J.Wurdack | 2021 | Journal of Systematics and Evolution2021，59，5： | 0 |
