| 備註: 植株好幼, 尺寸似小飛揚SIZE; 莢果形跟長度是重點 (thanks crawford's info) Indigofereae 木藍族 Indigofera 木藍屬 草本 具匍匐性 木藍屬全球品種數目超過700多種，為豆科下第3大屬。木藍族被毛有一種相當特別的二叉毛，換成中植誌的用詞就叫丁字毛。不同品種的二叉毛，都有幾種形態：有開展／平伏，有兩邊等長／兩邊異長。 圖庫本地木藍屬收錄的品種只有5種，其中小葉互生 就 Indigofera hendecaphylla 一種。不過發現地點為人群聚居之地，週圍有不少外來栽植植物，所以才看得深入一點。因為其實都有好幾隻近似品種。 Thanks Crawford's info FOC: Indigofera hendecaphylla has been misidentified as the African and SW Asian species Indigofera spicata Forsskål by Y.
