LONDON BOTANICAL EXCHANGE CLUB. 71 
Typha angustifolia, L. Lopwell, Devon; T. R. A. Briggs. Addi- 
tional to sub-province 2. 
Cladium Mariscus, Br. Sent by Dr. Trimen from Penally, Pem- 
brokeshire. Additional to sub-province 17, of Cyb. Br. Suppl. 
Scirpus glaucus, Sm. This usually maritime plant is sent from two 
inland stations. Mr. Bromwich contributes it from a marsh near 
Itehington Holt, Warwick (new to sub-province 14), and Mr. Fox, 
from a pond at Mitcham, Surrey. Though placed in the London Cata- 
logue as a variety of S. lacustris, L., it seems to come very near to 8. cari- 
natus, Sm., from which, indeed, it is not easy to find good distinguish- 
ing characters. The glumes of S. glaucus have indeed more rough 
points upon them than those of S. carinatus, as found by the Thames, but 
the glumes of the latter are by no means smooth as Koch states. 
Babington says that the lower bract overtops the panicle in S. carinatus, 
but this character does not hold good. 
Carex incurva, Lightf. Gathered this year on the sandy shore of 
Holy Island, off the coast of Northumberland, by Mr. Ralph Tate. It 
has not been recently collected south of Forfarshire and Kincardine. 
Gastridium lendigerum, Gaud. In 1867, very abundant in a field 
of wheat, near the school-house, at Oxshott. Rare and inconstant in 
North Surrey ; H. C. Watson. 
Arundo stricta, Schrad. Mr. Robinson states that Oakmere, 
Cheshire, where this grows, is about 550 feet above sea-level. The 
altitude is omitted in Cyb. Brit. — 
Bromus serotinus, Beneken. We are favoured with a communica- 
tion from Herr von Nechtritz, of Breslau, pointing out that a plant 
sent to him from England, under the name of Bromus asper, gathered 
by Mr. Charles Bailey, near New Mills, in Derbyshire, must be re- 
ferred to the B. serotinus of Beneken, which is regarded as a distinct 
species by several recent German authors. The characters relied upon 
as distinctive, are :— 
B. asper. Lower sheaths and leaves shortly and stiffly hairy ; upper 
ones naked or nearly so; lower branches of the panicle in from threes 
to sixes, 
B. serotinus. All the sheaths and leaves densely clothed with longer 
hairs ; lower branches of the panicle only two and far apart. 
Descriptions will be found in Wirtgen’s ‘ Flora of the Rhine Prc- 
vince,’ and Von Garcke’s ‘ Flora of Northern and Central Germany,’
