Abstract
Two species of Syrrhopodon [S. japonicus (Besch.) Broth. and S. armatus Mitt.] were newly recorded from Jeju Island. S. japonicus was found on a rock covered with fine soil on the Che-oreum Volcano. This species is clearly distinguished from other species of the genus by its plants to 40 mm long, leaves bordered with several rows of short cells, and the margins at the leaf shoulders being regularly serrate. Syrrhopodon armatus was found on tree bark on Seopseom islet. It differs morphologically from other species of the genus in terms of its plant at 10 mm long, leaves bordered with one to several rows of linear and hyaline cells, leaves with spinous teeth at the shoulders. We propose new Korean names for these two species: 'Seon-o-reum-i-kki' and 'Jag-eun-seon-o-reum-i-kki,' respectively, which are based on their plant size and their first locations in Korea.
미기록 분류군 선오름이끼[Syrrhopodon japonicus (Besch.) Broth.]와 작은선오름이끼(Syrrhopodon armatus Mitt.)가 제주도에서 발견되었다. 선오름이끼는 제주도 체오름에서 채집되었고, 식물체의 크기는 약 40 mm이며 기부 가장자리에 치돌기를 가지고 있는 것으로서 근연분류군인 작은선오름이끼와 구별된다. 작은선오름이끼는 제주도 섶섬에서 채집되었으며, 식물체의 크기는 약 10 mm이고 잎 기부에는 긴 가시돌기를 가지고 있는 것으로 선오름이끼와 확실히 구별된다. 식물체의 크기 및 채집지의 이름을 따서 국명을 명명하였다.
