BRISTOL FIELD-BOTANY IN 1901. 141 
Clark, to have been more abundant. R. acutus L. has been 
specially searched for, and proves to be well distributed in the 
district. In the experience of some botanists it ripens fruit 
very sparingly, but local observation with reference to this 
point bears out Prof. Babington's assertion that the nuts are 
produced in abundance. 
Polygonum ^naritimum L. In addition to several other 
good finds for which we are indebted to him, Mr. Harold 
Thompson showed me, from Berrow sand-hills, a specimen 
of this very rare plant which has never before been observed

Buxus senifervirens L. Abundant in woods about " The

Boxwell, outside the district, the box covers many acres and 
extends half a mile. The reasons for beheving this shrub to 
be truly wild in the West Gloucestershire portion of the Bristol 
district have been fully stated by C. Bucknall in the Journal 
of Botany, 1901, p. 29.

Salix. The arrangement of Willows in the Flora would be 
revised in a new edition to accord with the results of later 
study and investigation. 
ORCHIDACEiE. 
Orchis ustulata L. I am indebted to Mr. W. F. Miller for 
a specimen found by him on Wavering Down. The locahty 
on Clavferton Down has been visited by Mr. D. Fry, who saw
