Data from: Two new synonyms in Heteranthera (Pontederiaceae, Commelinales)

Hydrothrix and Scholleropsis, two segregate monospecific genera placed within the Heteranthera s.l. clade, are here transferred to Heteranthera based on phylogenetic and morphological data. A brief discussion on the morphology and affinities of Heteranthera s.l. is given, along with the designation of lectotypes for the two new transfers.

Hydrothrix与Scholleropsis为两个分立的单型属，原隶属于广义异蕊花属（Heteranthera s.l.）演化支。本研究基于系统发育与形态学数据，将二者转移至异蕊花属（Heteranthera）。本文简要讨论了广义异蕊花属的形态特征与类群亲缘关系，并为这两个新组合的类群指定了后选模式标本（lectotype）。
