台灣新紀錄苔類：東亞白錦苔

Leucoloma okamurae Broth., A Newly Recorded Moss Species in Taiwan

過去臺灣僅有 1 種白錦苔屬植物—柔葉白錦苔的紀錄，本文報導臺灣新近發現的東亞白錦苔，並提供本種的形態描述、圖片、棲地及分布等資料。東亞白錦苔與柔葉白錦苔的分別在於，東亞白錦苔植物體較小，長約 1 cm 以下、葉不會脫落、葉細胞壁表面有粗疣，以及葉緣在葉中部 4–6 列細胞分化成葉舷。 In addition to Leucoloma molle (Müll. Hal.) Mitt., L. okamurae Broth. was recently found, making the species number of the genus up to two in Taiwan. L. okamurae can be distinguished from L. molle by its smaller plant, which is shorter than 1 cm in length, scarcely deciduous leaves, median laminal cells with multiple large papillose, and leaf margins bordered by 4–6 rows of linear cells in the middle of leaf.Here we provide descriptions, illustrations, habitat information, and geographical distribution of L. okamurae.
