Bentham (1846) mentioned the provenance and collector for the type of Euphrasia glandulosa in the protologue. After checking the potential type material conserved at the herbarium of the Royal Botanical Garden, Kew (K), we found that the herbarium sheet K 000951256 is part of the original material. Therefore, that sheet is here designated as the lectotype.

Pseudobartsia glandulosa is a critically endangered species in China, only two gatherings, Ying-Bo Zhang 0004 (Fig. 1) and Qi-Wu Wang 8477 (collected in 9 October 1940 in Yanshan of Southeastern Yunnan). We visited the type locality Longtanying of Songming on 8 October in 2007, but failed to locate any individual.
