At first sight this ylndrcea may be distinguished from its con- 

 geners by its more robust appearance, and by the more striking 

 character of its leaves being imbricated on all sides of the stem, 

 and never in the least secund. The var. j8 is remarkable for its 

 large size, as well as its paler colour and more distinct leaves. 

 7 might without a careful examination of the leaves be almost 

 taken for a distinct species, and differs from a and ^ in having 

 the stems as well as branches peculiarly straight and erect, the 

 latter of so equal an height that they form compact tufts, of 

 which the surface is as even as if cut with an instrument. 



Although Andraa cdpina has been given as a native of several 

 parts of the North of England and Wales, yet I am inclined to 

 think it may be numbered among our Musci rariores, and that 

 A. rupcstris has been often mistaken for it. Thus much I can 

 say, that most of the specimens under the name of A. alpina^ 

 from the last-mentioned places, that I have had an opportunity 

 of seeing, have proved to be ^. rupestris; and on Ingleborough^ 

 where it is said to have been gathered, Mr. Dalton and myself 

 were only able to find rupestris and Uotliii. In Scotland, indeed,
