Abstract

Cyclosorus fukienensis Ching (Thelypteridaceae), a new record for the flora of Vietnam, was studied, compared and described. Before, this species only distributed in China (Fujian, North Guangdong, South Hunan, South Jiangxi, South Zhejiang). This species differs from the closely related species Cyclosorus interruptus (Willd.) H. Itô and Cyclosorus acuminatus (Houtt.) Nakai in its shape of the stipe bases, lobed, veinlets, soris, spores. In this paper, we introduce original reference and relevant references, type, detail morphological descriptions, distribution and habitat, specimens examined, color photograph, the key and the table compares the characteristics with the close species (Cyclosorus interruptus (Willd.) H. Itô, Cyclosorus acuminatus (Houtt.) Nakai). Specimens of Cyclosorus fukienensis Ching were collected in Kbang district, Gia Lai province and kept in the Herbarium of the Institute of Ecology and Biological Resources, Hanoi, Vietnam (HN). This research provides the checklist of vascular plants for the flora of Viet Nam.
