中国东南部复苏卷柏一新种:东方卷柏 ——基于形态学和分子生物学证据
Selaginella orientali-chinensis,a new resurrection spikemoss species from southeastern China based on morphological and molecular evidences
摘要
Abstract
Selaginella tamariscina(Beauv. )Spring and S. pulvinata(Hook. et Grev. )Maxim. are two closely related rosette forming and resurrection spikemoss species widespread in Asia. In this paper ,Selaginella orientali-chinensis Ching et C. F. Zhang ex H. W. Wang et W. B. Liao was described and illustrated. This species was closely related to S. tamariscina and S. pulvinata and previ-ously misidentified as S. tamariscina. By the gross morphological and molecular evidences,we found that this species is easily distinguished from S. tamariscina and S. pulvinata by the absolutely dichoto-mously branched main stems. Our field works confirmed that this species is widely distributed in south-eastern China and mainly inhabits Danxia landforms areas. In some cases,this species shares the same habitats with S. tamariscina. Illustrating the morphological,phylogenetic and distribution characters of this new species would provide new data for the taxonomic studies on the genus Selaginella in the future.关键词
