介绍了葫芦科一新种Trichosanthes sunhangii，张德国，李志明，刘群，邓廷涛。采集于中国中东部湖北省神农架林区。T. sunhangii在形态上与T. kirilowii Maxim相似。但可以很容易地通过其苞片、卷须和果实与它们区分开来。基于ITS、matK和rpl20-rps12 3个DNA条形码标记的系统发育分析表明，在小苞叶组中，sunhangii的2个种质聚在一起（PP=1.00， BP=100， LP=100）。
Trichosanthes sunhangii D.G.Zhang, Z.M.Li, Qun Liu & T.Deng, a new species of Cucurbitaceae, is described and illustrated. It was collected in Shennongjia Forestry District, Hubei province, east-central China. T. sunhangii is morphologically similar to T. kirilowii Maxim. and T. rosthornii Harms, but can be easily distinguished from them by its bracts, tendrils and fruits. Phylogenetic analyses based on three DNA barcode markers (ITS, matK and rpl20-rps12) indicated that two accessions of T. sunhangii were grouped together (PP=1.00, BP=100 and LP=100) in Sect. Foliobracteola.
