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 insigniter
decurrentia, superna subemarginata et undulata. Sub-
stantia minutissime reticulata.
This species undoubtedly belongs to the same natural family
of Jungermanniie as J . asplenioides, J . spinulosa and J. dicho-
ioma, {Carpolopedium dichotomum of P. de Beauvois,) differing
from all in the quite entire margins of the leave.?, but most resembling
the last mentioned plant. The fructification is unfortunately
unknown.
Schwaegrichen has placed this plant in his division “fo liis
dentatis,” but in all my specimens I have observed that the
leaves are entire.
