毛菍（野牡丹科），台灣植物誌新增物種

Melastoma sanguineum Sims (Melastomataceae), an addition to the Flora of Taiwan

我們在台灣北部植物調查發現毛菍（Melastoma sanguineum Sims，野牡丹科）之野生族群，為台灣植物誌未曾紀載之物種。本種為灌木或小喬木，高可達3m，葉表面近光滑，莖、葉柄、花梗、花托筒及果實被開展之長剛毛，可明顯與本屬其它物種區別。本文提供該種的形態描述、彩色圖片及台灣野牡丹屬植物檢索表以協助鑑定。

During the course of our botanical survey, wild populations of Melastoma sanguineum Sims, heretofore unknown for the Flora of Taiwan, was observed from northern part of Taiwan. Melastoma sanguineum can be easily distinguished from other congeners in Taiwan because it grows up to 3 m tall and has subglabrous leaf surfaces, and spreading bristles covering stems, petioles, pedicels, hypanthium and fruits. Here we provide a detailed morphological description, illustrations and a key to the Melastoma species in Taiwan for identification.
