FLORA OF OXFORDSHIRE. 407 
CAMPYLOPUS, Brid, 
C. flexnosus, Brid. 
Moist shady banks in rocky or gravelly soil; frequent in mountain 
districts, rare here. April. Wychwood Forest; also Bagley Wood and 
Powder Hill Copse, scarce, growing with the next species. 
C. torfaceus, Br. & Sch. 
C. pyriformis, Brid. 
Gravelly and sandy ground amongst bushes, and on heaths and com- 
mons. April. Ramsden Heath; Headington Wick Copse; Shotover 
Hill; Bagley Wood, Wootton, and Cumnor, Berks. Fruits very freely. 
LEUCOBRYUM, Hampe. 
L. glaucum, Linn. (Bryum.) 
Moist heaths, moors, and shady woods. April. Rare here, and not 
fruiting; the foliage continues unchanged till frost. "Woods near Nettle- 
bed, Sibthorp about 1790, and plentiful there in 1859, 1866 ; Woods near 
Goring, 1877 ; Powder Hill Copse near Cumnor, very scarce. 
The late Mr. Baxter told me about 1860 that this moss had existed 
in Bagley Wood twenty years before, but I sought in vain for it. Like 
some others it seems exterminated in that place. 
CERATODON, BPrid. 
C. purpurens, Linn. (Bryum.) 
Tops of old walls, banks, and gravelly heaths, also on thatched roofs ; 
frequent. April. Less common than in some counties; generally the 
commonest of mosses, next to Funaria, and like that found all over 
the world. 
Seligeria pusilla should be found on the chalk in the south of the county; 
it occurs in similar situations in Bedfordshire, whence it has been sent by 
Mr. Saunders, and probably it exists in the south of Oxfordshire though 
hitherto I have not met with it. 
FISSIDENS, Hedw. 
F. exilis, Hedw. (?) 
F. Bloxami, Wils. 
Shady banks and sides of woods in clayey soil; either rare or overlooked 
from its minuteness. February, March. Stockley Wood near Asthalleigh ; 
Tar Wood ; Watereaton Copse ; borders of Bagley Wood and Pusey Wood, 
Berks. 
F. pusillus, Wils. 
F. viridulus, var. pusillus, Bryol. Brit. 
Hedge-banks and bushy places, on stones and earth; rare, February, 
March. Roadside near Hailey ; rough banks above the Windrush near 
Witney.
