Systematic studies for a new system of tribe Desmodieae (Leguminosae)

本研究旨在完善豆科凤蝶科蝶叶属的现有系统。石斛属被认为是石斛科中最原始的属，在印度支那地区有分化。然而，最近在新几内亚和澳大利亚发现了一种以前被安置在石斛中的石斛。该种为灌木石斛（Dendrolobium arbuscula），与近缘种D. umbellatum和新种D. papuacola H. Ohashi & T. Nemoto有明显区别（项目贡献#4，Ohashi, Ye and Nemoto 1999）。多神经石斛（Dendrolobium polyneurum， S.T. Blake） H. Ohashi在澳大利亚被发现并归入该属（该项目的贡献#3，Ohashi 1998）。对菲律宾的石斛属（Dendrolobium）进行了修订，确定了4个不同种，包括1个新种d.g esinkii H. Ohashi（本项目贡献1，Ohashi 1998）。在菲律宾特有种Desmodium属中，澄清了D. bolsterii是属于Heteroloma剖面的一个独特种（本项目贡献#2，Ohashi 1998）。由于其在形态和花粉粒上的各种特征在属中是不同的，因此在分类上的地位是不同的。直流。被修订并被认为是不同于刺草。提出了一种新的属种来容纳该物种（项目贡献#6，Ohashi 1998）。lepedeza hisauchi T.

This study aims to improve the present system of the tribe Desmodieae in Papilionoideae of Leguminosae. The genus Dendrolobium has been considered to be the most primitive genus among the tribe Desmodieae and differentiated in Indo-China region. Recently, however, a species of Dendrolobium which was previously accommodated in Desmodium was found in New Guinea and Australia. This species, Dendrolobium arbuscula, was clarified its distinctness from allied species D. umbellatum and a new species D. papuacola H. Ohashi & T. Nemoto (Contribution #4 in this project, Ohashi, Ye and Nemoto 1999). Dendrolobium polyneurum (S.T. Blake) H. Ohashi was found in Australia and transferred to the genus (Contribution #3 in this project, Ohashi 1998). Dendrolobium of the Philippines was revised and four species including one new species, D. geesinkii H. Ohashi, were recognized as distinct (Contribution #1 in this project, Ohashi 1998). In genus Desmodium, a Philippine endemic species, D. bolsterii was clarified as a distinct species belonging to section Heteroloma (Contribution #2 in this project, Ohashi 1998). Since its various features in morphology and pollen grains are distinct among the genus, the taxonomic position of Desmodium caudatum (Thunb.) DC. Was revised and considered to be distinct from Desmodium. A new generic Ohwia was proposed to accommodate this species (Contribution #6 in this project, Ohashi 1998). Lespedeza hisauchii T. Nemoto & H. Ohashi was described based on L. daurica Nakai, non (Laxm.) Schindl. in Tokyo and Kanagawa Prefectures.
