BRISTOL FIELD-BOTANY IN 1901.

Agrostis pumila has been detected on the Mendips near 
Cheddar. The Polypogons have both disappeared from the 
district as it was anticipated they must do sooner or later. 
Molinia coerulea. This species has abounded at intervals during 
the last few years on both Chfton and Durdham Downs, where 
it was long since gathered by Dr. H. 0. Stephens. It grows 
also in a swamp near Abbotsleigh. Glyceria flicata was not 
included in the Flora, but is now known to be frequent in the 
Chew valley, on Syston Common, and elsewhere. G. pedi- 
cellata Towns, which is very possibly a hybrid, with characters, 
however, much nearer those of fluitans than plicata, has been 
gathered at Abbotsleigh, Pensford, Newton Park, and Law- 
rence Weston. Hordeum sylvaticum Huds. [Elymus europwus 
L.) was added to the local flora in 1897 by Mr. C. Bucknall, 
who detected it on the wooded hills between Dursley and 
Wotton-under-Edge. It appears to be a dainty grass, growing 
only in full shade, sparingly, and often under beech trees where 
no other vegetation exists. Alien grasses that have been met 
with about Bristol are Phleum Michelii, Apera Spica-veiiti, 
Gynosurus echinatus, Briza minor, Bromus unolioides, and 
Elymus Caput- Medusce. 
LYCOPODIACEiE. 
Miss Gregory, walking over Blackdown from Burrington 
to Shipham, August 3, 1896, came upon a large patch of 
Lycopodium davatum. A beautiful specimen in fruit was 
gathered. 
EQUISETACE^. 
Lastly, I have to mention the very remarkable occurrence 
of two horse-tails that have been found growing together in 
some quantity near Weston-super-Mare : E. hyemale L., and 
E. variegatum Schleich. Neither of these species had pre- 
viously any certain record in the county of Somerset.
