sent us. " The work will be comprised in about seven or eight 12ino 

 fasciculi — price 3s. 6cl. each — forming two neat pocket volumes. On 

 the left hand page of each leaf, one, two, or more specimens of a 

 species will be carefully gummed, with the scientific and English 

 name, reference to the page of the British Flora where the species 

 is described, locality, and time when found, — all accurately written 

 underneath. With the concluding fasciculus will be given, along 

 with title-pages for both volumes, a printed table of the contents of 

 each, arranged according to Sir W. J. Hooker's British Flora, and 

 including a synopsis of the generic and specific characters. A blank 

 will be left at the top of each page for numbering the species, and 

 by means of the tables the specimens can be numbered and arrang- 

 ed with the greatest ease, while the numbers not being attached 

 to them when published, will allow of any subscriber adopting what- 

 ever mode of arrangement he chooses, as well as of the author add- 

 ing species that may be found during the publication of the work." 



Northumberlmid Flora. — At the July meeting of the " Berwick- 

 shire Naturalist's Club," the members, in the course of their walk, 

 discovered the Asplenium ,yfi/;/e«/no«/a/e growing in great profusion, 

 on Kyloe crags, near Haggerston. The Hieracium molle was gather- 

 ed in Kyloe dean ; and the Blyssmus rufas abundantly in a salt 

 marsh at the mouth of the Low below Beal. The two former plants 

 are not included in Mr Winch's " Floraof Northumberland and Dur- 

 ham;" and for the latter, two localities only are given, both in the 

 south of Durham. Dr Francis Douglas exhibited a specimen of 

 Cladium mariscus, which he has discovered native in Learmouth 

 Bogs, Northumberland, where, however, it is not plentiful, but a 

 very interesting addition to the botany of the district. If to these 

 we add Dr Johnston's discovery of Cerantium atrovirens, we have 

 sufficient evidence that the zeal in the investigation of indigenous 

 botany for which the northern botanists of England have been long 

 noted, is not grown lukewarm.
