terminali et laterali obovato inflato dorso convexo ventre obtu- 
sissime bicarinato mucronato, mucrone in appendiculo cyathiformi 
expanso. 
This small species approaches very near to Z. serpyllifolia in 1s ze 
and appearance, but the leaves are thinner although the cells are of 
the same size, the lobule is narrower; the perianth is inflated, and 
with only two very obtuse angles at the top on the ventral side, the api- 
culus is expanded into a curious eup-shaped appendage.

The stems of this species are sometimes six inches long and of a 
pale whitish-yellow colour. In some respects it comes near to Z. cerina, 
particularly in the form of its leaves and stipules, which are however 
more distant and their texture is more lax: the perianth is very mi- 
nute and scarcely protrudes beyond the leaves, by the emission of the 
capsule it is burst into four acute laciniæ; the pedicel is so short that 
the capsule remains barely out of the mouth of the perianth.

Except in size, this species scarcely differs from S. bipinnatum (Sw.), 
Mitten. The name Sarcomitrium of Corda has been adopted for this 
genus, in preference to Axeura which implies that the plants are nerve- 
~ less, when in reality they are almost entirely composed of nerve. Be- 
. Sides the species described in the < Synopsis Hepaticarum" under 
~ 4hneura, the genus Sarcomitrium must contain those comprised in the
