風花菜（Rorippa globosa（Turcz.）Hayek）為十字花科葶藶屬植物，廣泛分布於俄羅斯和中國。本種早有文獻記載分布於台灣，可能由於本種植物十分少見，近年來常被忽略遺漏，但亦有文獻明確指出本種分布於台灣中部和南部地區。本文描述其分類特徵、花粉形態、染色體數目和相關特性。 Rorippa globosa (Turcz.) Hayek, belonging to the mustard family Brassicaceae, is widelydistributed in the temperature region of Russia and mainland China. It was reported from Taiwan asearly as in 1896, but because of its extremely rarity, it has been ignored recently from the flora of Taiwanby many authors, even Shen (1996) verified it to be in the central and southern Taiwan. This paperdescribes R. globosa with color photographs, SEM micrographs of pollen grains, chromosome number,taxonomic notes and distribution in Taiwan.
