A small species, which agrees very nearly witb A. Mariei, 

 Bescb., from Nossi-be ; but the apices of the leaves are wider 

 and their nerve is not papillose. Among the small specimens 

 gathered there is no indication of the stems being tomentose 

 with rootlets.

 e cellulis distinctis areolatis. — M. Lycopodioides, C. MiilL, Eohm.
