通过比较形态学和分子系统发育研究了澳大利亚北部 Tristicha australis C. Cusset 和 G. Cusset 的系统亲缘关系。这两方面的证据都表明它与 Malaccotristicha malayana (J. Dransf. & Whitmore) C. Cusset & G. Cusset 关系最为密切，但与 Tristicha trifaria (Bory ex Willd.) Sprengel 不同，因此形成了 Malaccotristicha australis 的命名组合。这表明 M. australis 迅速获得了与 Malaccotristicha 不同但与 Tristicha 相似的特征形态。从系统发育地理学来看，与热带的亚洲姐妹相比，澳大利亚的豆科植物（M. australis）和 Cladopus queenslandicus (Domin) C. D. K. Cook & Rutishauser 两个物种可能是源自澳大利亚。为 Tristichoideae 物种提供了一个密钥，以区分 M. australis 和其他物种。
The systematic relationship of Tristicha australis C. Cusset & G. Cusset in northern Australia was investigated by comparative morphology and molecular phylogeny. Both lines of evidence show that it is most closely related to Malaccotristicha malayana (J. Dransf. & Whitmore) C. Cusset & G. Cusset and distinct from Tristicha trifaria (Bory ex Willd.) Sprengel and consequently the nomenclatural combination of Malaccotristicha australis is made. It is suggested that M. australis rapidly gained its characteristic morphology that is distinct from Malaccotristicha and resembles Tristicha. Phylogeographically, Australian Podostemaceae with two species, M. australis and Cladopus queenslandicus (Domin) C. D. K. Cook & Rutishauser, are probably derived, compared with the tropical Asian sisters. A key is provided to the species of Tristichoideae to distinguish M. australis and the other species.
