澳洲木山螞蝗（豆料－蝶形花亞科：山螞蝗族）

Dendrolobium polyneurum (S. T. Blake) H. Ohashi from Australia (Leguminosae-Papilionoideae: Desmodieae)

產自澳洲的澳洲山螞蝗（Desmodium polyneurum S. T. Blake）因其花序上每節具一朵花、雄蕊為單體、花粉為三溝孔粒，故鑑定為木山螞蝗屬（Dendrolobium）之成員，並將其學名重新組合後改成為澳洲木山螞蝗Dendrolobium polyneurum (S. T. Blake) H. Ohashi。本種最為相近的植物為白木蘇花Dendrolobium umbellatum (L.) Benth.。

Desmodium polyneurum S. T. Blake (Leguminosae-Papilionoideae: Desmodieae) described from Australia is regarded as a member of the genus Dendrolobium on the basis of its inflorescences having one flower per node, monadelphous stamens and reticulate tricolporate pollen grains. A revised description of the species is presented. Dendrolobium polyneurum (S. T. Blake) H. Ohashi is most similar to Dendrolobium umbellatum (L.) Benth.
