Studies of Vietnamese Pteridophyte Flora 3.

ABSTRACT: This is the third paper in a series dedicated to updating the knowledge of the Vietnamese pteridophyte flora. Based on recent collections, we first reported three new national records of ferns: Haplopterisyakushimensis, Lindsaeakohkongensis, and Pterispseudowulaiensis. Secondly, we conducted phylogenetic analyses to investigate the placements of Lindsaeakohkongensis and Leptochiluspoilanei, each based on three plastid DNA markers. Our results revealed that Lindsaeakohkongensis is sister to L.ensifolia, while Leptochiluspoilanei is embedded within L.cantoniensis. We discussed these results in the context of systematics. Lastly, we reported chromosome numbers for 20 fern species in Vietnam. For seven of these species, including <
