[Auli Campbell's Islands. | CRYPTOGAMIA ANTARCTICA, 11 
It is with much reluctance that we refuse to adopt the views of Bruch and Schimper, who, in their beautiful 
* Bryologia Europea,’ subdivide Splachnum into three or four genera. The several characters which the two species 
here enumerated possess and which are not conformable with those of any of the subgenera alluded to, would, were 
mbricatis Conary these adopted, oblige us to construct a fifth for their reception. 4S. octoblepharum and S. purpurascens are so nearly 
Compactun, jj allied to the S. mnioides, that we doubt the propriety of even retaining two genera which might be founded on the 
very dissimilar structure of the calyptra, but on that character alone, unaccompanied with any difference of habit. 
opodio guai sh In one of Bruch and Schimper's divisions, Tefraptodon, the calyptra is truly dimidiate and neither inflexed nor ap- 
pendiculate at the base; in the other, we always find it, previous to its separation from the vaginula, inflexed at the 
base, but when the seta elongates and carries up the calyptra, this inflexed portion is drawn out and remains as a lace- 
rated and somewhat incurved membrane or appendage. A similar structure is observable in Schlotheimia, under 
which genus the development of S. guadrifida is illustrated. , 
0 separate it ge In all the species which we have had an opportunity of examining in a recent state, and especially in S. sphe- 
e more acute d ricum, ampullaceum and mnioides, there is a very peculiar arrangement of the sporules, in lines radiating from the 
ly belong to amb columella. Each of these lines is composed of eight or more sporules, contained either in separate cells or in mem- 
marks, “a ail branous tubes, of a nature evidently analogous to the asci of some Fungi. This structure is probably common to 
ong leaves of wa all the species and may be traced obscurely in the dried state of some; it has, however, escaped the observation of 
ties Bruch and Schimper, who perhaps did not examine specimens in a sufficiently young state.

Nearly allied to S. octoblepharum, but larger, the leaves wider, more distant, less produced at the apex and 
more crisped when dry. Capsule narrow and more attenuated below, with a smaller mouth. In the var. 8, both 
the two lateral of the longitudinal and the transverse lines on the teeth are very faint; in no instance do the teeth 
ens agree wiht in this species appear to be really formed of four, the lateral lines always ceasing below the apex; the lower part of
