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).
