Bay, and that the old coastHne of sand-hills has been enclosed 
for many years. In this way R. spinosissima became screened 
from observation, but a good deal of it is still there, along a 
line of — say — 400 yards. Mrs. Gregory finds this rose near 
the Town Quarry, and in one or two other spots at that side 
of the wood at Weston-super-Mare, thus confirming Dr. 
Stephen's old record. Eespecting the var. Briggsii of R. 
micrantha, from St. Thomas' Head, there is an interesting 
note by M. Fran9ois Crepin in Journal of Botany, 1897, p. 216, 
from which it appears certain that, although Mr. Briggs 
himself repeatedly named the Somerset plant R. Briggsii, 
the rose is really R. senium Thuill {inodora Fr.). The var. 
Briggsii appears to be of extreme rarity. It is characterized 
by its pedicels, receptacles and backs of the sepals being 
completely eglandular. Plymouth remains the only British 
station for the true plant. Additional varieties of R. canina 
that have been noted in the district are frondosa, deciyiens, 
cwsia, andegavensis, dumetorum and vinacea.

Epilobium Lamyi F. Schultz was first recognized in the 
district by Mr. D. Fry, at Corston and Hanham, in 1890. 
It was afterwards found on colliery waste near Kingswood, 
and at Fox Wood Quarries. Specimens from all these locali- 
ties agree well with those gathered by Wirtgen. The area of 
E. lanceolatum, one of the rarest British species, has been 
lately extended into Somersetshire by its discovery at Bris- 
lington, Keynsham, Abbotsleigh, and Hallatrow ; but the 
plant does not appear to be known anywhere else in the county. 
Nearly all the species of this genus hybridize very freely, with 
the result as regards Bristol that we have become acquainted 
with several crosses : hirsutum X montanum, ohscurum X 
montanum, Lamyi x montanum, Lamyi X lanceolatum, and 
tetragonum X ohscurum. It has been dogmatically asserted
