general taxon notes:
Boulaya is endemic to East Asia with only one species. Boulaya mittenii (Broth.) Card. was first reported from Mt. Changbai, Jilin province (C. Gao 1977). We recently found it from Xizang. It shows a discontinued distribution from Mt. Changbai to the Himalayan region. The genus Boulaya is closely related to Abietinella, but differs from the latter by the weakly plicate stem leaves, multipapillose median leaf cells, and the erect capsules.
