222 GUERNSE Y. 
Welisia viridula, Hedw. 
Common on earthy banks and hedges in all parts. 
Weisia mucronata, B.&S. (Mollia rutilans, Braith.) 
Pleinmont Point. 
(Weisia verticillata, Brid., I have found in Alderney at the base 
of dripping cliffs: and Trichostomum crispulum, Bruch., on banks. 
near the sea.) 
Trichostomum mutabile, Bruch. (Molla brachydontia, Braith.) 
Common on banks and old walls, and among rocks on the cliffs : 
fruiting sparingly in 1892 at Vauxbelets and near Beaucamps. 
Var. cophocarpum, Schp. Specimens from Fermain Bay and 
Petit Bot Waterlane were so named for me by Boswell. 
Trichostomum littorale, Mitt. (d/o//ia, Braith.) 
Rather common throughout the island on old walls and banks, 
and on the sandhills at Lancresse. Braithwaite allows this moss to 
rank as a species, but Dixon considers it a variety of mutabile. A 
curious form growing on rocks above high-water mark at Petit Port 
which I submitted to Boswell was named by him TZ7ichostomum 
(Mollia) lutescens, and it was recorded by me under that name in 
the two papers mentioned above. Dr. Braithwaite, however, has 
since informed me, after an examination of the plant, that it is not 
the true Mollia lutescens of Lindberg. The latter is considered by 
Dixon to be simply a rather marked form of the very variable 
TZ: mutabile. 
Trichostomum flavo-virens, Bruch. 
Frequent all round the coast on sandy banks, and in rock crevices. 
close to the sea. 
Pleurochaete squarrosa, Lindb. 
Common on the sandhills at Lancresse: frequent on the cliffs. 
Rare inland: Talbots Valley. 
/ 
ORTHOTRICHACEAE. 
Zygodon viridissimus, Brown. 
Generally distributed and rather common, occurring more often. 
on walls and stones than on trees. Fruiting on walls at the 
Hermitage, St. Martin’s, and at St. Andrew’s Churchyard. 
Var. rupestris, Lindb. Couture Waterlane. Foote’s Lane, 
Lower Rohais. Wall at Lancresse. 
Zygodon Stirtoni, Schp. 
On a wall at Portelette, Rocquaine.
