Caulis repens filiformis foliis plerumque destitutus, ramosus, ra- 
mis bi-triuncialibus erectis, iterum ramosis, ramulis plerumque 
patentibus, attenuatis. Folia obscure viridia arcte bifariam 
imbricata exacte disticha, verticalia, horizontaliter patentia, 
plana, ovato-oblonga, omnino integerrima, basi inferna insig- 
niter decurrentia, superna subemarginata et undulata. Sule 
stantia minutissime reticulata.

This species undoubtedly belongs to the same natural family 
of Jungermannice as J. asplenioides, J. spinulosa and J. dicho- 
toma, (Carpolopedium dichotomum of P, de Beauvois,) differing 
from all in the quite entire margins of the leaves, but most re- 
sembling the last mentioned plant. The fructification is unfor- 
tunately unknown, 
Schwaegrichen has placed this plant in his division ¢¢ foliis 
dentatis,” but in all my specimens I have observed that the 
leaves are entire.
