Agropyron caninnm^ Beauv. South Stoke, W. Sussex, June 
1908. — T. Hilton. II. Foremark, Derbyshire, July 1908. — T. E. 
Routh and W. Bell. Yes, quite typical from both localities. — 
E. Hackel. 
Scolopendrium vulgare, Symons. Root from an ancient hedge- 
row above Shipham on-Mendip, N. Som., 31st Mar. 1905. A most 
peculiar form, having the frond-margin frilled, and the frill appears to 
be seamed on. — J. W. White. This appears to agree with forma 
S. papillosa (Moore), described and figured in Lowe’s ‘ Native 
Ferns,’ p. 234, Fig. 597, as found in Guernsey by Mr. Jackson. 
The distinctive feature is a series of distinct wartlike excrescences 
on the upper surface of the frond near the margin forming a kind of 
border. Sori oval; fronds 6 to 18 in. in length. — W. B. 
= Phyllitis Scolopendrium, Newm. — G. C. Druce. 
Polypodium rulgare, L., var. serratum, Willd. Cwrtyrala Estate, 
Cardiff, v.-c. 41, 1908. Growing with var. cambricum, Willd. I 
suppose this is what is meant by var. serratum. It is not recorded 
from Glamorgan till now. — H. J. Riddlesdell. I think this is 
correctly named. The serralion in some of the specimens has 
a leaning towards crenation . — W. Bell. 
Polypodium vtdgare, L., var. cambricum, Willd. Still growing 
in Ray’s old locality, near Cardiff, 14th Sept. 1908. Only sent on 
account of the historic interest. The fronds are at their best in A pril. 
— H. J. Riddelsdell. This and the var. serratum are very accept- 
able contributions as one so seldom sees them except in cultivation. 
— W.' Bell.
