developed, agree closely with those found in typical L. clausa. I would 
therefore retain the variety /? as a form of this species, hardly distinct 
enough to deserve a varietal name. 
Two other species which should also be included among the synonyms of 
L. clausa are L. commutata Gottsche, and L. lutea Mont. The first of these 
has already been reduced by Stephani, and a portion of the type from the 
Neesvon Esenbeck herbarium, although sterile and fragmentary, fully sup- 
ports his view. L. lutea was described from Cuban material collected by 
Ramon de la Sagra and is regarded as a valid species of the subgenus 
Euosmo-Lej eunea by Stephani. I find a few fragments of the type in the 
Lindenberg herbarium, one of which bears a single female inflorescence, but 
can discover no characters which would. warrant a separation from L. clausa . 
The fact that Stephani refers L. clausa to Cheilo-Lej eunea, while he places 
L. opaca and L. lutea, which I am unable to separate from L. clausa , in 
Euosmo-Lej eunea makes it evident that the relationship between these two 
groups is unusually close. At the same time it seems to me that L. clausa 
has more in common with Euosmolej eunea than with Cheilolejeunea and 
would therefore give its synonymy as follows:

Frullania obcordata. 
The material upon which Frullania obcordata was based was collected 
in “Guiana” and sent by Hooker to Lehmann. Two specimens, evidently 
portions of the type, are present in the Lindenberg herbarium and show an 
autoicous inflorescence with numerous perianths and short male spikes. They 
fully agree with the plant from the Southern States which Sullivant 
described as a new species under the name F. caroliniana. This species 
must therefore be reduced to synonymy, although it has been more or less
