FLORA OP THE BRISTOL COAL-FIELD. 



121 



Calamintha officinalis, Moench, var. Briggsii. 



Among brambles and long grass near the Avon, under 

 Leigh Wood. One of the most interesting of recent 

 discoveries, as previously it had only been seen in 

 Devonsliire. I noticed this variety about two years 

 ago, but did not feel sure of its identity until I had 

 submitted an example to Mr. Briggs, who confirmed 

 the name, remarking also that in his opinion the 

 form was of small importance, and scarcely worth 

 separating. In its extreme state, however, this 

 plant differs widely from the type, especially in the 

 peduncles of the lower verticillasters, which ai'e 

 sometimes an inch and a half long, exceeding the 

 pedicel of the central flower of the cyme. More- 

 over, it is larger and lankier in all its parts, show- 

 ing a marked divergence in the direction of 0. 

 sylvatica. C. Briggsii is well figured in " Engli.sh 

 Botany." 



Salix acuminata, 8m. 



See FL, p. 172. The willow that stands under this 

 namo would more correctly be referred to S. rugosa, 

 Loefe i and the latter should bo classed as a species 

 rather than as a variety of 6'. Smithiana, WiUd. 

 The name acuminata is now restricted to a ddfer- 

 ent plant, which has not yet been found within the 

 limits of our district. 

 Juncus compressus, Jacq., m West Gloucestershire. Com- 

 municated by Mr. D. Pry. 



This apparently rare and little understood species, 

 whioli, according to Watson, has been frequently 

 confused with the closely allied but much com- 

 moner /. Gerardi, Lois, was found in fair quantity
