80 APLOPERISTOMI. [Weissiu. 



It may be remarked, that in the general growth and habit, 

 and in the form and structure of the leaves, there is the greatest 

 similarity between the present individual, ( W. StarkeanaJ 

 and W. lanceolata ; and their only essential differences are to 

 be found in the operculum and teeth of the peristome. 



7. W. lanceolata; stems somewhat elongated, leaves ovate with 



an excurrent nerve almost piliferous, capsule ovate, lid ob- 

 liquely rostrate. (TAB. XIV.)

This plant is only to be distinguished from W. Starkeana (to 

 which it is very nearly allied,) by the larger size, by the nar- 

 rower leaves, their laxer reticulation and more excurrent nerve, 

 and by its rostrate lid. In general habit it approaches Gym- 

 nostomum truncatulum, particularly the larger varieties of it, 

 but its leaves are more erect and more closely imbricated, and 

 the apiculus is longer. We have examined authentic specimens 

 from Dr. Mohr of his Grimmia aciphylla^ and we fully accord 

 with Schwaegrichen that it is not to be distinguished from our 

 plant. 



8. W. latifolia; stems unbranched very short, leaves broadly 



obovate with a small acumen concave imbricated shining, the 

 nerve reaching nearly to the point, capsule oblong cylindrical 

 erect, lid rostrate. ( SUPPL. TAB. III.)
