( Fig. 2 A-D)

SPECIMEN EXAMINED. — Vietnam. Lâm Đồng, Dalat , Manline , sur bois en forêt Claire d’Ericacées , 1300 m, Tixier 276 ( PC [ PC0764723 ]).

NOTES

Accompanied by Bazzania tridens (Reinw., Blume & Nees) Trevis. , B. tridens var. tridens , Frullania obscura (Sw.) Mont. and Plicanthus birmensis (Steph.) R.M.Schust. A species maybe new to science, what needs confirmation. It has similarity by its always bidentate, caducous leaves with papillose cuticle to B. friabilis from Sabah ( Kitagawa & Kodama 1975: 68, fig. 1) also found in peninsular Malaysia ( Cheah & Yong 2016). But the leaves of Tixier’s plant are more oval with margins less crenulate and the trigones of cell walls, although have midline, are much less bulging. Finally, the underleaves possess larger teeth, they are more lobate, almost star shaped.
