臺灣植物誌之觀察（4）──合歡屬（豆科）

Notes on the Flora of Taiwan (4)–The Albizia Durazz. (Leguminosae)

本文共處理五種合歡屬（Albizia）植物，合歡（A. julibrissine）、山合歡（A. kalkora）、大葉合歡（A. lebbeck）、黃豆樹（A. procera）、鈍葉合歡（A. retusa）。其中大葉合歡為栽培種。本文確認鈍葉合歡為自生種，首次將長梗合歡（A. longepedunculata）處理為山合歡之同物異名。

A taxonomic treatment of the genus Albizia in Taiwan is provided in this report. Of the five species of Albizia, A. julibrissine, A. kalkora, A. procera and A. retusa are native while A. lebbeck is a cultivated species. Albizia longepedunculata is here treated as a synonym of A. kalkora for the first time. Albizia retusa is reconfirmed as being native.
