Foliola foliis triplo minora, valde diaphana, ovali-orbiculata, ad 4 bifida, 
sinu segmentisque subacutis. 
Flores monoici: @ in ramo brevi terminales, innovatione  suffulti. 
Bractez foliis majores obovatze obtuse, lobulo duplo breviore line- 
ari-rhomboideo acuto; bracteola obovata breviter bifida, segmentis

Plantula facile distincta, affinitate inter Harpa-Lejeuneas et Micro-
