one, and partly made in order to renew my acquaintance with a few of tlie mosses and 

 liclicns wliich grow in the nciglthourhood of Bolton -hridge, Burden, Sec. With the 

 idea that local lists of plants often prove interesting to botanists, I now send you the 

 following additions to the list given by Mr. Spruce, (Phytol. 197). I hope my friend 

 Mr. S. will pardon the use of the more practical names of Leighton's Catalogue, in 

 preference to those of Hedwig, Bridel, <*Scc. ; for would it not have been just as well 

 understood if he had called his Grimmia rivularis G. apoearpa, var. a. nigro-viridis, 

 Hooker, and for Weissia fugax said W. striata, var. a. minor. Hooker;' For the We- 

 issia striata of Hooker is Bryum crispatum of Dickson, Grimmia striata of Sehrader, 

 Weissia Schisti of Schwa;grichen, and the Grimmia Schisti of the ' Flora Britannica.' 

 Mr. Spruce may be right, but if we carry out this plan where are we to stop ? for so 

 great is the multiplication of synonymes in this department of Botany, that it has be- 

 come a matter of difficulty in some eases to decide which name ought to be adopted.
