Hedwigia emodica Hampe ex Müll.Hal., Flora 61: 82. 1878.

Type:— N. W. Himalaya. INDIA. Or. [‘Rolegurtz’] No. 651 & 1582 (Syntype: in herb. Hampe in BM).

Note:— Hedwigia emodica is highly similar to H. mollis , but can be distinguished by leaves with longer hyaline apices and leaf cells covered by densely arranged papillae that obscure the cell walls, making cell wall outlines hardly visible, whereas H. mollis has relatively compact papillae that do not obscure the cell walls and make longitudinal cell rows conspicuous ( Ignatova et al. 2016). Hedwigia emodica has been reported in Russia ( Ignatova et al. 2016, 2017), Finland ( Pihlaja et al. 2023), India, Nepal, and China (Yunnan, and Sichuan) ( Dalton et al. 2013). In China, the present study expands its range to Heilongjiang, Inner Mongolia, Jilin, Liaoning, Shaanxi, Xinjiang, and Xizang.
