中国植物区系已有46种，是中国薄荷科第五大属之一。目前的分类将马鞭草从马鞭草科中移除，将其置于兰科中，使许多中国物种的身份难以确定。本研究根据植物的起源，并参考了植物标本馆（包括类型）和新鲜标本，将草属植物归为富尔瓦属植物的同义植物；其中，calcicola（属）、crassa var. bijiangensis（属）、crassa var. yuii、P. dopii、P. puerensis、P. shunningensis（属）、P. straminicaulis、P. yuanjiangensis（属）和P. yunnanensis（属）被认定为tapintzeana。花冠小，雄蕊近等长，被花冠筒包围，萼长5个钝裂片，等唇或稍2唇，两者相似，但叶片和花冠上唇的形状、小枝的毛被、叶柄和花梗的形状及生境不同。本研究提供了完整的富尔瓦和黄皮瓦的分类处理、地理分布和生态观察。
With 46 species recognized in the Flora of China, Premna is now one of the fifth largest genera in the mint family in China. Current classifications have placed Premna in the family Lamiaceae removing it from the family Verbenaceae, leaving the identity of many of the Chinese species difficult to resolve. In this study, based on protologues, and consulting both herbarium (including the types) and fresh specimens, P. crassa is reduced to synonymy of P. fulva; P. calcicola (ined.), P. crassa var. bijiangensis (ined.), P. crassa var. yuii, P. dopii, P. puerensis, P. shunningensis (ined.), P. straminicaulis, P. yuanjiangensis (ined.) and P. yunnanensis (nom. illeg.) are recognized as P. tapintzeana. Premna fulva and P. tapintzeana are similar to each other by having small corymbs, subequal stamens enclosed by the corolla tube, and equal or slightly 2-lipped calyces with 5 obtuse lobes, but also different in the shape of leaf blades and upper corolla lips, the indumentum of branchlets, petioles and peduncles, and their habitat. The present investigation provides complete taxonomic treatments, geographic distributions and ecological observations of P. fulva and P. tapintzeana.
