B. mtemiptus, Druce in ‘Pharm. Journ. Suppl.’ (October 5th, 
1895), ‘ Journ. Bot.’ (December 1895), and in ‘Linn. Soc. Journ.’ 
(1896), pp. 426-430. In a field of vetches in the parish of Brightwell 
Salome, Oxon., June 1901. Exception has been taken to the citation 
of the species from ‘ Pharm. Journ. Suppl.,’ because the species is not 
diagnosed there ; but the plant itself had been previously diagnosed by 
Prof. Hackel in Hit., and published by me in ‘ B. E. C. Report ’ (1888), 
p. 240, as a variety of Bromus mollis under the name interruptus. 
Subsequent study, however, revealed that it possessed claims for 
specific distinction, and I accordingly named it as a species in the 
above periodical; and this has priority over either the ‘Journal of 
Botany,’ where a brief diagnosis was given, or the ‘Journal of the 
Linnean Society,’ where a full account and description are pub- 
lished. — G. Claridge Druce. “The two specimens in my parcel 
striking me as rather poor examples led to my examining them, and 
finding all the flowers opened on one plant with the palea entire, and all 
I opened on the other with the palea sjilit to the base. It then became 
evident that the specimen with the entire palea had all the appearance 
of being B. mollis^ L., and not B. interruptus, Druce; it is, in fact, 
B. mollis, var. glabratus, Dcell. The full account of B. interruptus 
occurs in ‘ B. E. C. Report,’ 1895, PP' 5°3'4> where Mr. Druce 
raises it to a species. Mr. H. Beeby questions whether it is not a 
monstrosity rather than a species ; Prof. Hackel hesitates between a 
species and an anomalous form, believing the split palea to have 
originated from some abnormal state ; and the editors of the ‘ Report ’ 
(Messrs. Groves) report that ‘ Dr. Stapf and Mr. Rendle considered 
this (plant) a monstrosity rather than a species.’ It would be inter- 
esting to learn what is i’rof. Hackel’s matured opinion, h'rom the 
time when I first found it, near Thetford, Norfolk, June 1882, and 
tried through IMr. Arthur Iknnett to get a name, but in vain, and so 
let it be, I have always regarded it as a B. mollis variety, and do not 
see reason to alter this view.” — E. I'. Linton. “ I also think this too 
closely allied to B. mollis. 'I'he ‘Pharmaceutical Journal’ is not a 
strictly botanical publication ; new species would be more fitly pro- 
posed in some more representative organ.” — Ed. 
B. arvensis, L {teste kx. Bennett). Canal bank, Aintree, v.-c. 59, 
South Lancashire, July 1901. — J. A. Wheldon.
