Cowan, Jun. Yes. — G. Claridge Druce. This variety is, 
according to description, twice the height of the specimen sent. — 
H. J. Riddelsdell. Very good capillare. The size is of no im- 
portance 3 nor does Hoffmann mention it in his original diagnosis 
(‘Deutschland Flora,’ 1795, part ii., p. 3 ). — Edward S. Mar- 
shall. 
Azolla caroliniana, Willd. Sunbury, Middlesex, August 1910. 
This hydropterid is abundant on a drain running from the direction 
of the water-works into the Thames. Wooden supports placed for 
the purpose of strengthening the sides of the drain prevent the 
Azolla from being carried into the river 3 nevertheless, as the plant 
produces organs of reproduction at this locality, it is quite likely to 
be found in some still part of the adjacent river. This species is 
quite naturalised in Middlesex, where, for years past, it has been 
known to grow at White Webbs, near Enfield. — C. E. Britton. 
Yes, but it was recorded by Mr. Odell from Pindon, Middlesex, in 
‘Science Gossip’ for 1883. This year our member, Mr. W. A. 
Harford, sent it me from Norfolk ; and Miss Ridley has also 
gathered it in the Thames, near Henley. In the Landes district 
of France it is a more aggressive species 3 and, covering the water 
as it does with its dense growth, it is very inimical to other aquatics. 
— G. Claridge Druce. 
Chara fragilis, Desv., var. delicahila, Braun. Pool in an old 
clay-pit between Rangeworthy and Hall End, West Gloucester, 
July 16, 1910. — James W. White. This is a form which might be 
called Chaj'a fragilis, Desv., sub-sp. delicatula, forma capillacea. 
- — H. and J. Groves. 
Chara contraria, Kuetz. In the abandoned canal near Dun- 
kerton, North Somerset, June 25, 1910. Gathered in compny with 
Mr. Cedric Bucknall. New to the county of Somerset. Two forms 
<of the plant are represented here 3 one, from shallow water in full 
exposure to sun, is compact and full of fruit 3 the other, from a 
deep shaded pool, is diffuse, dark tinted and barren.— James W. 
White. This is Chara vulgaris, L., a somewhat “ longebracteata ’ 
form. The larger and greener specimens are young, and the 
other smaller and more encrusted ones are older and have ripe 
<vuit _H. and J. Groves.
