    Abstract

    Aphyllodium (DC.) Gagnepain is adopted as the correct generic name instead of Dicerma DC. Narrower circumscription of A. biarticulatum is adopted, and the following new combinations are made: Aphyllodium australiense (Schindl.) H. Ohashi, A. hispidum (Schindl.) H. Ohashi, A. hispidum var. collettii (Schindl.) H. Ohashi, and A. novoguineense (Schindl.) H. Ohashi. Key to all the taxa included in the genus is prepared.

    中文摘要

    二節豆屬(Aphyllodium)分佈在印度、緬甸及澳大利亞北部。大橋廣好原認為Dicerma與Aphyllodium 有親緣關係。現在根據第一苞片及小苞片間之差異而重新提升亞種為種。二節豆屬學名採用Aphyllodium而捨棄Dicerma。同時亦採用Aphyllodium biarticulatum狹義種之觀念，並將亞種提升為種之新組合處理，包括A. australiense (Schindl.) H. Ohashi，A. hispidum (Schindl.) H. Ohashi，A. hispidum var. collettii (Schindl.) H. Ohashi，及 A. novoquineense (Schindl.) H. Ohashi 等。本文亦提供本屬內所有分類群之檢索表，以供參考。 關鍵詞：二節豆屬，豆科，新組合名。
