1924. Short stature, narrower greener leaves, and smaller heads 
than the type. Perhaps only an ecological state. — H. S. Thompson. 
This is a small state of riparia apparently, but is not var. humilis 
Uechtr. according to a plant Kiikenthall so named for me. That 
had shorter spikes and shorter glumes, and the perigynia of a 
different shape. Uechtricht says of his plant that the smaller 
examples almost resemble C. distans, and the larger ones remind 
one of C. nutans Host. — C.E.S. 
C. riparia Curt, forma. Ref. No. 2425. Slender ecological 
form with narrow green leaves, but of at least normal height. In 
half -dry sandy swamp, Burnham-on-Sea, Somerset, June 8 and 
28, 1924. A dense vegetation, and consequent want of brilliant 
light is the probable cause of this form. — H. S. Thompson. 
C. riparia Curt. Intermediate in vigour between 2424 and 
3435. — C.E.S. 
C. saxatilis L. Meall Gfarbh, Mid Perth, v.c. 88, July 16, 
1913. — W. A. Shoolbred. Yes. — C.E.S. 
Spartina stricta Roth. Canvey, Essex, 1924. — J. L. O’Lough- 
lin. Correctly named. — W. 0. Howarth. 
Phleum phleoides Simonkai. Furze Hills, Hildersham, Cambs., 
June 5, 1924. — A. J. Crosfield. Yes. — W.O.H. 
Agrostis nigra With. Fortingal, mid Perth, v.c. 88, July 15, 
[913. — W. A. Shoolbred. A. ?iigra With. = A. vulgaris With. 
I see no reason for removing this from the type as described by 
Babington (ed. IX. p. 491) or Ascherson and Graebner n. i. 1900, 
p. 179 — 180). The ligules are short and truncate; the panicle 
branches have few soft hairs. — W.O.H. 
Polypogon ni07ispeliensis Desf. Cardiff Docks, Glamorgan, v.c. 
41, Sept. 1924. Naturalised on mud flats. — A. E. Wade. Comm. 
Nat. Mus. of Wales. Yes. — W.O.H. 
Avena fatua L., var. glabrata Peterm. Near Reculver, Kent, 
v.c. 15, Sept. 11, 1924. — W. R. Sherrin & C. E. Salmon. Comm. 
S.L.B.l. Det. C. V. B. Marquand. 
A. fatua L., var. pilosa Druce. All data as above. 
Phragmites communis Trim, var. nigricans G. et G. A large 
colony at high-water mark at extreme mouth of River Brue, N. 
Somerset, Sept. 19, 1924. 1^ to 3 ft. only in height, and of 
slender growth. — H.S.T. Arundo Phragmites , var. subuniflora 
Asch. & Graeb. — W. 0. Howarth.
