venule obsoleta iis parallele ; lobate, lobis inzequalibus, plerumque rotundatis, obtusis, obscure crenatis vel 
sinuatis, summis soriferis. 
Sori lobos occupantes, plerumque duo vel tres in singulo lobo. 
Involucra nervos terminantia, substantia frondis immersa, cylindracea, basi attenuata, superne dilatata, brevissime

This grows in dense tufts, and in a dry state has an appearance not unlike that of Jungermannia 
epiphylla. As a species of ZTichomanes it comes near, perhaps, to the 7v. parvulum of Poiret 
(7. Sibthorpioides Willd.), and to the 7'. minutum of Blume: but both these, according to the 
descriptions, are considerably smaller in size and have much deeper laciniw. Still these simple- 
fronded species of the genus are so variable in the outline of the frond, that without figures or 
very full descriptions it is scarcely possible to determine the species intended by authors.
