Abstract

Dendrolobium quinquepetalum (Blanco) Schindl. Is distinct from Dendr. Umbellatum and is endemic to Luzon and Mindoro in the Philippines, although it was reported also from New Guinea and Australia (Queensland). The specimens from New Guinea and Australia are referable to Desmodium arbuscula Domin for which Dendrolobium arbuscula (Domin) H. Ohashi is proposed here as a new combination. This species is new to New Guinea and also is found in Fiji.

中文摘要

五瓣木山螞蝗(Dendrolobium quinquepetalum (Blanco) Schindl.) 是菲律賓之特有種，並與白木蘇花(Dend. Umbellatum)有所區別，雖然它曾被處理為後者之異名並被報導，亦分布於新幾內亞及澳洲昆士蘭區。在新幾內亞及澳洲被誤認為是五瓣木山螞蝗之標本，應鑑定為木山螞蝗(Desmodium arbuscula Domin)，本文並將其學名新組合為Dendrolobium arbuscula (Domin) H. Ohashi。木山螞蝗是新幾內亞之新紀錄種，同時亦分布於斐濟。 關鍵詞：木山螞蝗、五瓣木山螞蝗、白木蘇花、斐濟、豆科、新組合名、新幾內亞。
