FLORA OF TILE BEJSTOL COAL-FIELD.

to be resolvable into one super-spooies through 

 intermediate states. 



Juncus diffusus, Iloppe. 



Now to Somerset. A specimen of this littlo-nuder- 

 stood, and apparently very rare plant, sratliorod at 

 Dean, near Cranmoro, has been received from the 

 Eev. R. P. Murray, who says that it was con- 

 sidered diffusus by Mr. T. 11. Archer Briggs. 



Calamagrostis lanceolata, Roth. 



An addition to the " Flora." On a recent visit to 

 Mr. T. B. Flower, that gentleman showed me, in 

 his herbarium, specimens of this grass, labelled 

 in Mr. Thwaitcs' hand-writing, "Arnndo Calama- 

 grostis, JAmi. Filton Meads, Gloucestershire, 

 Aug., 1846. G. H. K. Thwaif.es" It is probable 

 that, if carefully searched for, the plant will still 

 be found existing at the locality given on the 

 label.
