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

本研究旨在完善豆科蝶形花科山蚂蝗族的现有系统。石斛属是山蚂蝗族中最原始的属，在中南地区已分化。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山蚂蝗属中的石斛属物种。阐明了该种与近缘种D. umbellatum和一新种D.巴布亚科拉湖Ohashi & T. Nemoto（Contribution #4 in this project，Ohashi，Ye and Nemoto 1999）.多脉石斛Dendrolobium polyneurum（S.T. Blake）H. Ohashi在澳大利亚被发现，并转移到该属（本项目贡献#3，Ohashi 1998）。订正了菲律宾石斛属Dendrolobium的4个种，其中包括一新种D.吉辛基湖Ohashi，被认为是独特的（贡献#1在这个项目中，Ohashi 1998）。在菲律宾特有种山蚂蝗属（Desmodium）中发现了山蚂蝗D. bolsterii被澄清为一个独特的种属于组Heteroloma（贡献#2在这个项目中，Ohashi 1998）。本文讨论了尾山蚂蝗Desmodium caudatum（Thunb.）DC.经过修订并被认为与Desmodium不同。提出了一个新的属Ohwia以适应该物种（该项目的贡献#6，Ohashi 1998）。长柄胡枝子根本& H. Ohashi是基于L. daurica Nakai，non（Laxm.）辛德尔在东京和神奈川县。

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.
