臺灣新歸化茜草科植物──雪亞迪草

Sherardia arvensis L., A Newly Naturalized Plant in Taiwan

雪亞迪草（Sherardia arvensis L.）屬茜草科（Rubiaceae）植物，首次在南投縣信義鄉塔塔加附近被採集，為臺灣新歸化植物，本屬亦為新歸化屬。本篇報告描述其形態特徵、地理分布及生育環境，並提供彩色圖片與繪圖。 Sheradia arvensis L. is recently found in the central part of Taiwan. This monotypic genus is newly naturalized in Taiwan, too. The morphology of Sherardia is very similar to Galium. It is distinguished from Galium by its densely clustered flowers in a capitulum. The habitat, the periods of the flowering and fruiting, distribution, photographs, and a detail line drawing, along with some taxonomic notes are given.
