II. Old Park, Y. and B.; Sowe Waste Canal; pool, near Till Hill 
Wood. 
This does not seem to be more than a form or state of E. limosum. 
E. hyemale, Linn. Rough Horsetail. 
Native; In ditches. Very rare. 7,8. 
I. In a moist ditch at Middleton, towards Drayton, Ray. Gough's 
Cavib., 350. 
I have examined all the ditches near and about Middleton, but 
have not been able to find this plant. 
CHARACE^E. 
CHARA. 
C. flexilis, Linn. (Nitella). Flexible Chara. 
Native : In ponds and pools. Rather rare. June to September. 
I. In the third stew, front of the house at Edgbaston, With., Ed. 3, 4 ; 
abundant in a pool near Hartshill, 1884, Olton Pool; 1881 in 
company with Mr. James Groves, abundant in a pond near 
Olton Pool; Earlswood Reservoir ; abundant in a small pool 
on Forshaw Heath. 
II. Ditches about Drayton, Part. ii., 435; in a pond near Warwick, 
II. R. ; canal, near Ansty. 
C. opaca, Ag. Syt. Alg. Opaque Chara. 
Native : In ponds and pools. Rare. May to September. 
I. Sutton Park, in Bracebridge Pool and Stews; pool, by Honily 
Poors Wood ; Dickens, near Earlswood ; 1883. 
C. translucens, Ag. Syt. Alg. Great Translucent Chara. 
Native : In ponds and ditches. Very rare. June. 
II. In ponds and ditches, near Rowington, //. Bromwich. 
I have not been able to find this plant in this district, or in any part 
of the county. It is many years since it was found, and as these 
plants were then little understood may be incorrectly named. 
C. vulgaris, Linn. (Chara). Common Chara. 
Native: In pools v ponds, ditches, canals, &c. Local. May to 
September. 
Var. A. vulgaris. Apparently rare. 
I. Bracebridge Pool, Sutton Park ; Kingsbury Wood. 
II. Pond, near Ckadsliunt. 
Var. B. lougibracteata, Kfitz. More frequent, but local. 
I. Drains, Water Orton ; Earlswood Reservoir. 
II. Corley Heath, Kirk.; small pool, near Chadsliunt; ditches, near 
Harbury Railway Station ; small pool, near Drayton Bushes ; 
pool, near Stratford-on-Avon; canal, near Bishopton and 
Wilmecote ; pool, near Napton-on-tlie-Hill; Napton Reservoir ; 
Flecknoe, near Shuckburgh; old lime quarry, near Little 
Lawford ; canal, near Newbold-on-Avon ; canal siding, Ansty. 
Var. c. papillata, Wallr. Very rare. 
II. Cattle pond, near Itchington Holt. 
A form closely allied to this was abundant in a pit near Little 
Lawford, almost choking up this pit with its growth ; two years later I 
again visited the same pit, and found that although there was an 
abundance of the var. lougibracteata , not a trace remained of the 
papillata form. The plant from Itchington Hall disappeared entirely 
after the first year, and was also replaced by the variety above cited. 
E. crassicaulis, Kfitz. Very rare.
