lie writes, “ It seems to be later in flowering than R. rostellata , which 
grew with it, as it was in flower while R. rostellata was in seed. 
The peduncles of R. maritime, i elongate before flowering and rise out of 
the water, the flowers being often an inch or more above the surface. 
I have not seen this in R. rostellata 
TFolffia arrhiza , Wimm. Dr. Trimen sends plants collected this 
year at Staines, where it is still abundant, though apparently confined 
to a single piece of water. 
Typlia angustifolia, L. Lopwell, Devon ; T. B. 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 
Itchington Holt, Warwick (new to sub-province 14), and Mr. Pox, 
from a pond at Mitcham, Sunny. Though placed in the London Cata- 
logue as a variety of S. lacustris, L., it seems to come very near to S. 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 «;ood. 
Car ex incurva, Lightf. Gathered this year on the -sandy shore of 
Holy Island, off the coast of Northumberland, by Mr. Kalph 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. Bare and inconstant in 
North Surrey ; II. C. Watson. 
Aritndo stricta, Schrad. Mr. Bobinson 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- 
sent to him from En o _ ___ __ 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 : —
