Stegnogramma leptogrammoides (Thelypteridaceae), its discovery in China, and synonymy

The northwest region of Yunnan province (southwest China), belonging to the Pan-Himalaya, is a hotspot of biodiversity. We report Stegnogramma leptogrammoides from Yunnan as a new discovery for China. This species was identified based on morphological comparison with the type specimens of all similar species, and DNA barcoding was performed to obtain additional evidence. As it was previously recorded to be endemic to Sikkim, the new record provides a case for confirming floristic affinities between Sikkim and Yunnan within the Pan-Himalaya at the species level.
