03E687FDE957D8254FBBF9E457ED40E3.taxon	diagnosis	Diagnosis: Being morpholgically distinct in habit, leaf shape and areolation from the related Hattoria and Vietnamiella it resembles Gymnocolea inflata and Odontoschisma fluitans. It differs from Gymnocolea inflata in the occurrence of some rhizoids or their fascicles from ventral leaf bases, lack of caducous perianths, outer cortical cells of larger shoots mostly ± smaller than inner stem cells, often tangentially orientated and occasionally thick-walled. It is distinct from Odontoschisma fluitans in the origin of some rhizoids or their fascicles from ventral leaf bases, distinctly striolate-papillose leaf and stem surface, and terminal furcate branching.	en	Potemkin, A.
