among the excluded. The range of latitude may also now 

 be entered as 53 — 60. But no estimate of provinces or 

 counties can j^et be given, which would be much better 

 than guess-work. Perhaps provinces 10, and counties 25, 

 might be not far from truth in regard to numbers. In 

 the sixth edition of the British Flora, the habitat of 

 " Near London " is still repeated, like a hundred others 

 that are far more likely to be inaccurate than true, and 

 thus quite as likely to mislead students as to give them 

 any useful information.

 Provinces 6 and 9 may be added in the area; the former 



on authority of Mr. Motley's list of Caermarthenshire 

 plants ; the latter on authority of " W. S." in the Floj-a of 

 Liverpool. Probably province 10 should also be added, 

 as Mr. J. G. Baker expresses an opinion that the so-called 

 C. submersum of Barnes's Yorkshire Flora, from the Foss 

 by York, belongs to the present species ; though the fruit 

 not having been seen by Mr. Baker, he cannot say cer- 

 tainly.

This has been reported from provinces 1 and 5 ; from 

 that of Peninsula, by Mr. Hort, who found the plant at 

 Woodspring, Somerset ; from that of Severn, or county of 

 Worcester, on the testimony of Mr. Roby. The province 

 of Humber, or county of York, may be an error ; for which 

 see the preceding species. Mr. Pascoe records this species 

 from Cornwall, on authority of Miss Warren, but failed to 

 find it himself in the station reported to him. Mr. Tho- 

 mas Moore finds it in Middlesex. Thus 7 provinces and 

 12 counties are reported, but some of them on very doubt- 

 ful authority.

Three provinces [12 9] have been added to the area,
