a long way up the leaf, all the rest of the basal cells being 

 thin-walled, rectangular, pellucid, and elongate (4-8 times 

 as long as wide), extending to some distance from the base 

 and only gradually passing into the short upper cells, 

 which are usually more angular, less sinuose and less 

 incrassate than those of G. homodictyon. 



Specimens have been submitted to Mrs. Britfon, and to 

 Mr. R. S. Williams, who knows G cah/ptrata well, 

 having gathered it in the field, and they agree in thinking 

 the Scotch plant specificaily distinct. I have to express my 

 indebtedness to them and also to M, Gardot, for notes and 

 specimens kindly sent me. 



G. homodictyon bears some resemblance to G, leiico- 

 phdda^ but the microscopical characters at once separate it, 

 the latter plant having much broader, less tapering leaves, 

 with plane margins, thin and indistinct nerve, and larger, 

 pellucid, sub-quadrate basal areolation. Only a single tuft 

 was found, but the characters are so distinct from any 

 European species of Grimmia, that there can be no hesita- 



tion about describing it The specific name refers to the 



/ 



unusually uniform character of the areolation

is erect in several exotic species, and the point is not of 

 sufficient importance to constitute a generic character. The 

 seta is described as half an inch long, the calyptra fim- 

 briate, but other characters are not given. As far as lam 

 aware the species had not been found in fruit again until 

 August, 1899, when Prof. T. Barker gathered the var. 

 elongatus Bosw. on rocks in the R. Llugevy at Pont-y-Pair, 

 Bettws-y-Coed, N. Wales, with 3 or 4 old capsules and a 

 few very young setae. Prof. Barker Kindly communicated 

 part of the gathering to me, asking me to put the occurence
