sandy parts, especially the sandy clays of the Middle Lias, the 
Harford Sands, and the Cotteswold Sands. 
I am indebted to Messrs. S. M. Macvicar and W. E. Nicholson 
for assistance in naming critical plants, and also to Professor 
Douin of Chartres for some remarks on Cephaloziella Limprichtii . 
As in my previous list of Mosses the number 33 (East 
Gloucester) or 34 (West Gloucester), after the name of the 
species or variety, indicates the “ vice county ” in which it is 
found. The total number of species found so far in the county 
is 95, of which 54 are found in East Gloucester and 93 in West 
Gloucester. The presence of fruit or perianths is sometimes 
indicated by the abbreviation c. fr. or c. per. 
Sphcerocarpus Michelii Bellardi. 34. 
In cultivated fields on the Keuper Sandstone about Newent 
and Bromsberrow. 
Sphcerocarpus texanus Aust. 34. 
This grows with the preceding, and is the more abundant 
of the two. They can readily be distinguished by their spores, 
which mature in March. The fields in which these plants grow 
are usually ploughed up before the spores are mature, except 
when a crop of clover follows the corn. 
Riccia. — Most of the plants of this genus are found in 
cultivated fields in places where the soil is suitable for their 
growth. They are particularly abundant on the Keuper 
Sandstone, but are rarely found on Keuper Marl, Lias Clay, or 
stony Oolitic soil. They occur in fields on the Middle Lias, 
but these being on the hill slopes are rarely cultivated, and also 
on sandy deposits on the Lower Lias Clay and other formations. 
Riccia Warnstorfii Limpr. 34. 
Fields near Newent and Bromsberrow. Perhaps only a 
form of the next species. 
Riccia commutata Jack. 34. 
Fields near Newent and Bromsberrow. Riccia nigrclla DC. 
grows with this species on similar soil at Redmarley in 
Worcestershire.
