, a new genus from southern Vietnam is described with a single species, . The new genus is morphologically most similar to and but it differs from the latter two by having four fertile stamens. Nuclear ribosomal internal transcribed spacer (ITS) region and plastid intron spacer () DNA sequence data from the new genus and eighty-seven species representing 42 genera within tribe Didymocarpeae are used to resolve its generic placement. The molecular evidence reveals that it is most closely related to rather than and . The chromosome number is counted as = that further clarified its distinction comparing to the related genera within tribe Didymocarpeae. A global conservation assessment is also performed and classifies as Critically Endangered (CR).
描述了一个来自越南南部的新属,该属仅有一个物种。这个新属在形态上与[属名1]和[属名2]最为相似,但与后两者不同的是它有四个可育雄蕊。利用来自该新属以及代表双蕊草族内42个属的87个物种的核糖体DNA内转录间隔区(ITS)区域和质体[内含子间隔区名称]内含子间隔区DNA序列数据来确定其分类位置。分子证据表明它与[属名3]关系最为密切,而非[属名1]和[属名2]。其染色体数目统计为2n = [染色体数目],这进一步明确了它与双蕊草族内相关属的区别。还进行了全球保护评估,并将[物种名称]列为极度濒危(CR)。
