Plagiothecium elegans, SuU. Cheviot (M.Fl.) 



[H. MDLCKNS, Wils. MSS., described by Dr Hardy in the ' Moss Flora,' 

 p. 472, appears to be referable to PLag. elegans. I have examined 

 the original specimen — "Hen Hole, Cheviot, July 1867; Jas. Hardy" — 

 in Wilson's herbarium, and although it has certain characters distinguish- 

 ing it from most forms of P. elegans, they do not, I think, constitute 

 a sufficient difference in my opinion to warrant separation, and that 

 appears to have been Wilson's final opinion, as his only annotations 

 are as follows : " Central basal cells seem different from normal H. 

 elegans!"' ; "? H. elegans var. /ol. latioribus ? No alar cellules." The 

 stems are elongate, the leaves wider at base and more ovate than 

 usual, and the areolation towards the base of the leaves especially 

 slightly laxer; but in other characters it agrees with P. elegans.
