SHORT NOTES. 



ToRTULA BREViRosTRis IN East YORKSHIRE. — A sliort time ago 

 Mr. J. J. Marshall, of Market Weighton, sent to me a specimen of 

 this rare British moss, which he had met with in October, 1895, in 

 a gravel-pit near to Kiplingcotes in the East Riding of Yorkshire. 

 Along with it in the same pit, Tortula stellata (Schreb.) Lindb., a 

 nearly allied species, was growing in abundance, whilst T. hrevirustris 

 was only found in small patches. Mr. Marshall, on looking over 

 his gatherings after getting home, detected the rarer moss amongst 

 them, and by careful examniation of its characters he concluded 

 that the smaller of the two plants he had collected must be this 

 rare moss ; he therefore sent me specimens, desiring me to confirm 

 his opinion. I possessed some American specimens from the Rocky 

 Mountain locality of this species, and with these the Yorkshire
