station. Cardamine flexuosa With., Oxalis Ascctosella L., and 
Euphrasia Rostkovia?ia Hayne are other species that flourish on 
this stratum of clay, and Epipactis violacea Bor. also grows there, 
but much more sparingly than on some of the neighbouring 
heights. — H.W.P. 
Lycopodium inundatum L. Near- Thursley, Surrey, v.c. 17, 
Sept. 1924. — I. A. Williams. Comm. S. Bond. B.I. 
L. annotinuni L. Moorland, 1700 ft. south-east of Dalwhinnie, 
E. Inverness, v.c. 96, July 20, 1911. — W. A. Shoolbred. 
Char a vulgaris L., ? var. longibracteata Kuetz. Near Bridge 
of Brown, Banff, v.c. 94, July 28, 1905. — W. A. Shoolbred. Yes, 
this has the long bract-cells, distant whorls, and inconspicuous 
spine-cells characteristic of this variety. — J. Groves. 
Tolypella ?iidifica Leonh. Loch Huisheek, Dunrossness, Shet- 
land, Aug. 11, 1924. — R. J. Burdon. Yes. — J. Groves. 
Nitella flexilis Agardh., teste G. R. Bullock-Webster. Mill 
House Pond, Mitcham Common, Surrey, May 2 and July 3, 
1924. — J. L. O’Loughlin. Although markedly protandrous, this 
plant is not the var. Fryeri Groves et Bullock-Webster, as the 
antheridia, are nearly normal in size. Since typical N flexilis 
grows on Mitcham Common ( teste G. R. Bullock-Webster), and 
H. and J. Groves gathered N. opaca from the same locality, if not 
from the same pond, it would not seem unreasonable to suppose 
that the hybrid N. flexilis x N. opaca might appear. The plant 
in question, which grows in dense masses over an area of about 
60 sq. yards in 2 — 4 ft. of water, appears very likely to be this, 
for we have : 
N flexilis characters : Monoecious. Antheridia and arche- 
gonia measurements. 
N opaca characters : Markedly protandrous (male organs 
were visible in March, and this is an approach to the dioecious 
character), dense fruiting whorls (a character ver}^ rare in 
N. flexilis , forming the var. nidifica Wallm), and the dark green 
colour. Further investigation in situ, however, will be necessary 
before any definite conclusions can be arrived at. — 1. L.

N. opaca Agardh., var. (1) Water of Conglass, Banff, v.c. 94, 
July 15, 1905.— W. A. Shoolbred. A small capitate form which 
is not uncommon.— J. Groves. (2) Stagnant pool by Bridge of 
Brown, Banff, July 17, 1905. — W.A.S. A diffuse form of N. 
opaca , mostly male. — J. Groves.
