ILLUSTRATIONS. — Zhou et al. 2012: 56, fig. 37; Meagher 2019: 357, fig. 33. NOTES In tropical Asia only this tiny species has a glaucous tint, due to the waxy particles on its opaque cuticle. Shoot 0.4- 1.0 mm wide, with contiguous side leaves. The quadrangular, often emarginate underleaves consist of hyaline cells except for very few green basal cell rows, like in B. tridens, but its leaves have distinct vitta made up of 2-3(4) cell rows near the ventral margin. This character is shared with a few other tropical Asian species (Schwarz et al. 2023). It usually grows on rotting logs or on bark of trees. Distribution: Malesian-Pacific, from Java through Australia to Tahiti (Kitagawa 1967).Published as part of Pócs, Tamás, 2023, New records for the liverwort and hornwort flora of Vietnam 2.
