FLORA OF OXFORDSHIRE. 429 
H. brevirostre, Ehrh, 
Woods, chiefly in mountainous districts. October, November. In the 
woods about Stokenchurch, Henley, Wycombe, and Marlow, occasionally, 
but not very common. Sometimes growing with Eurh. striatum which it 
much resembles in general aspect, and is hence liable to be overlooked. 
H. squarrosum, Linn. 
Woods, banks, lawns; common. November, December. Fruit rare. 
Stockley Wood near Asthalleigh; Coombe Wood near Cuddesdon ; 
Stokenchurch ; Bagley and Pusey, Berks. 
H. triquetrum, Linn. 
Woods and shady banks. November, December. Fruit rare. Wych- 
wood Forest ; Grave Hill Wood near Bicester ; Watereaton Copse; Head- 
ington Wick ; Stokenchurch; near Henley. 
H. loreum, Dill. 
Woods, chiefly in mountainous districts ; not common in fruit. Novem- 
ber, December. Near Stokenchurch, Goring, Henley, and Wycombe, 
occasionally, but capsules very scarce. This does not seem to occur in 
Wychwood Forest. It is fine in Gloucestershire. 
SPHAGNACEA. 
Peat Mosses. These form a very distinct tribe ; abounding in mountain 
regions, where they often grow in wide beds and cover extensive bogs 
which they eventually fill; they scarcely exist now in these counties 
except as here and there in small quantities, the survivors of a bygone 
time and different state of things. 
SPHAGNUM, Dill. 
S. acutifolium, Ehrh. 
Powder Hill Copse near Cumnor, scarce; amongst grass under shade of 
bushes, 1863. Vanishing or vanished since.

S. Mougeotii, Sch. 8. intermedium, Ehrh. 
Wychwood Forest, near Ramsden Heath; bog near Foxcombe Hill, 
Wootton, Berks, growing with S. cymbifolium and Polytrichum commune. 
S. cymbifolium, Dill., Ehrh. 
Wychwood Forest, near Ramsden Heath ; in Berks, fine near Foxcombe 
Hill, with recurvum, 1863, 1871; Bagley Wood and Powder Hill Copse, 
1870, 1876, a dwarfish state.
