1876. Not true Benekenii (i.e., not tlie Kensington Garden plant), 
but off the serotinus type in the Benekenii dii’ection. Interesting as 
being a small example of serotinus, and yet with several lowest-node 
panicle branches, it being usually only the full and luxuriant 
specimens of serotinus which develop extra branchlets. The pales 
seem rather more equal than m ordinary serotinus also, and rather 
more uniformly hairy. — J. L. Warren. I believe that the two 
forms, serotinus and Benekenii, are too much connected by mter- 
mediates to permit them to be ranked as more than varieties. — 
J. T. Boswell. 
Brachyjwdium 'pinnatim, Beauv., b. puhescens. Chalky banks 
near Eingwold, Kent, J. F. Duthie, July, 1876 ; and Clayton 
Tunnel, Brighton, Sussex, J. L. Warren, August, 1876. The 
pubescent form of B. pinnatuni is certainly less common than the 
glabrous, but a^ipears to be widely distributed. I have had it from 
Eev. T. A. Preston, from near Marlborough, Wilts. — J. T. Boswell. 
Triticum jnmge^is, Pers.” Koadside near tidal water, St. 
John’s, E. Cornwall. July 31, 1876. — T. E. Archer Briggs. 
T. acutuni, the form it assumes when growing in firm soil. Other 
specimens of p>ungens sent are correctly named. — J. T. Boswell. 
Lepturus incurvatus, Trin. Ballast, Bu’kenhead, Cheshh-e. 
July 18, 1876. — J. W. Burton. 
Hordeum sylvaticum, Huds. In two small woods, about two miles 
apart, and a mile from Bishop Auckland. Only recorded from two 
localities in South Durham. August 8, 1876. — J. P. Soutter. 
Equisetum variegatimi, Schleich., c. Wilsoni. Though so near 
trachyodon in character, yet this has a very different appearance 
when growing. The latter, I have observed, grows in rather a 
straggling manner, the former in large dense tufts of a dark green 
colour. The stems are more slender, and do not branch as much 
as in trachyodon . — S. A. Stewart. 
Chara syncarpa, ThuilL, var. opaca, Agardli. Mitcham Common, 
near Croydon, Surrey. May, 1876. Professor Babington, who 
kindly examined several Oharas for me, named these specimens as 
above. — A. Bennett. 
0. “ aspera.'’ Folkstone (the Warren), Kent. August, 1876. 
E. L. Baker. Professor Babington kindly called my attention to 
the erroneous name given to this Chara by remarking : “ Surely it 
is only C. hispida .” — T. E. A. B. 
[Eeceived from Dr. Boswell too late for insertion in the proper- 
place.] 
Senecio vulgaris, var. hibernicus, mihi. I now thmk the Cork 
plant, to which I gave the above name, must be S. vernalis, Wald- 
stein and Kitabel. Until this spring, I have never succeeded in 
getting it to survive the winter out of doors ; but now it is in 
flower in the open ground, and has a very different habit from the 
unbranched individuals grown in pots, on which my opinion of its
