C. clivisa Huds. On alluvium by River Avon, opposite Hot- 
wells, N. Somerset, v.c. 6, June 16, 1920. Very rare in Somerset 
and throughout the south-west of England. — H. S. Thompson. 
It is rather strange that this Carex of warm countries (it is un- 
known in Scandinavia) should be so rare in the south-west of 
England; only two stations are given in Mr. Davey’s “FI. of 
Cornwall,” and it is rare in Devon and Dorset. — A.B. 
C. Pairaei F. Schultz. Near South-Western Railway station, 
Midhurst, W. Sussex, v.c. 13, June 25, 1920. — R. J. Burdon. 
C. Pairaei F. Schultz. C. muricata L., subsp. microcarpa Neum. 
I think Mr. Burdon’s specimens are nearer C. contigua Hoppe ; 
the fruit is longer than is general in Pairaei. — A. Bennett. Yes, 
undoubtedly G. Pairaei. — C. E. Salmon. 
C. evoluta Hartm. ( C . lasiocarpa x riparia). Peat moor, near 
Street, Somerset, v.c. 6, June 6, 1920. Discovered there in 
1915. — H. S. Thompson. Up to 1879 Hartman still made this a 
species, though he quotes Wimmer’s “FI. Schl.” ed. 3, 1857, as 
C. riparia x filiformis. In the 1916 — 17 Report I see Andersson 
is not quoted as he should be in “Cyperacese Scand.” t. 8, f. 102, 
20 (1849). He has it there as a species, with no mention of being 
a hybrid. It is well figured in “FI. Dan. Supp.” t. 30 (1853). — 
A. Bennett. 
Agrostis tenuis Sibth., var. aristata Parn. Waste land by 
garden, Winchmore Hill, Middlesex, Aug. 8, 1920. Fide C.E.S. — 
L. B. Hall. 
Koeleria britannica Domin, det. Dr. Stapf. Limestone rock by 
River Avon, below Hotwells, Bristol, v.c. 34, July 7, 1920. — 
H. S. Thompson. True, the leaves are rather long and the 
spikelets glabrous, but Domin admits a glabrous form. — (). Stapf

Poa polynoda Parn., var. denticulata Parn. ? Wymondley Rd. £ 
Hitchin, Herts., v.c. 20, June 21, 1920. Fl.-gl. not webbed, 
denticulate on midrib. — J. E. Little. Seems to answer to Parnell's 
description, but a mere form, and polynoda is a var. of P. com- 
pressa L. — A. Bennett. This agrees with Parnell’s description 
and figure of his P. polynoda (with the exception of the upper 
leaf-sheath character ; this should be + the same length as leaf). 
It has the 5-ribbecl pale and non-webbed florets which Parnell 
relied upon to separate it from P. compressa, which is defined as 
having pales 3-ribbed and lower florets webbed. Parnell’s variety 
denticulata, of which a careful drawing is given, has the pale 
minutely toothed its whole length, and, although the pales in Mr.
