CRYPTOGAMOUS PLANTS OF DEVONSHIRE. 363 



The branches had not the character of innovations, 

 Fid. Hedw. St Cr. vol. 1. Tab. 5. Fig. 7. for 

 they all produced fruit at the same time. For 

 r distinction's sake, this variety may be called Ramo- 

 sum. It is a strong instance of the absolute neces- 

 sity of attending most closely to the generative or- 

 gans. 



(2.) Schistostega pennata. 



Very little about this curious moss appears to be 

 hitherto known. Hedwig mentions, that it was 

 found in Germany not long^ after its discovery by 

 Mr Newberry in Devonshire, and subsequent 

 publication by Dickson. Fid. Hedw. St. Cr. vol. 1. 

 Tab. 29- At Fig. 11., he gives so magnified a re- 

 presentation of the laciniated structure of the oper- 

 culum, that few would imagine it did not actually 

 exist. Yet I am informed by Dr Hooker, that this 

 structure is now denied by German botanists ; and 

 if they are correct, the plant must be carried back 

 to the genus Gymnostomum, from which Mohr re- 

 moved it. 



(3.) Polytrichum nanum. 



The excellent authors of the Muscohgia Britan- 

 nica, (p. 28.) have already signified their readiness 

 to consider P. abides and P. nanum, as the same 

 species; an opinion in which I heartily concur.
