Persicaria humilis (Polygonaceae) a Newly Recorded Plant in Taiwan

台灣蓼科新記錄－－矮蓼

Persicaria humilis (Polygonaceae) is newly recorded from Taiwan. Morphologically, P. humilis is very close to P. nepalensis but readily distinguished by the often much smaller habits, smaller leaves with sparse long glandular hairs on both surfaces and inflorescences without leafy involucres. 本文報導台灣蓼科新紀錄種－－矮蓼（Persicaria humilis）。形態上矮蓼與尼泊爾蓼（P. nepalensis）相當接近，但植物體通常更加矮小，葉片較小且兩面疏被長腺毛，花序亦無葉狀總苞。
