SOUTH WILTSHIRE MOSSES. 



By James Saunders. 



The following brief list of Mosses is issued with the hope that 

 it is preliminary to a comparatively exhaustive account of the Moss 

 Flora of Wiltshire, which is doubtless worthy the consideration of 

 the naturalists of the district. The specimens on which it is based 

 were gathered during a brief visit to Salisbury between the 5th and 

 10th of August, 1891, with the exception of those collected sub- 

 sequently by Mr. E. J. Tatum, as indicated by his initials. The 

 portion that was most carefully worked was Alderbury Common, 

 which contains a rich and interesting series both of flowering plants 

 and mosses. The general aspect of the flora of this Common is 

 strikingly similar to that of the New Forest, of which it originally 

 formed a part, the northern limit of the Forest extending as far 

 as Harnham Bridge, which is immediately within the southern 

 precincts of Salisbury. There are doubtless many ubiquitous 

 species that could be easily detected in the immediate vicinity of 

 Salisbury, but the list here appended is of those only of which 

 voucher specimens have been collected. A suite of type specimens 

 is being prepared for the Salisbury and South Wilts Museum, and 

 duplicates of the Bog Mosses for the British Museum. It is my 

 pleasing duty to express my obligation to Mr. Boswell, of Oxford, 

 for his help in naming the critical forms ; also to Mr. Blackmore, 

 of Salisbury, and to Mr. Tatum, for their assistance.
