Brachytliecmm ccespitosum Dixon. 8*. Plentiful at the base of 

 four trees at Tidcombe. 



Eurhynchium Swartzii Hobk. 7, 8. C.fr., under trees near 

 St. Katharine's Vicarage, Savernake Forest, as well as in the Grand 

 Avenue near the boundary between Tottenham Park and Savernake 

 Forest. I found this moss with capsules in a wet dripping hollow on 

 the coast near Ilfracombe, North Devon, and noticed that in the 

 latter locality the capsules were rather long and arcuate — in fact, 

 resembling those of E.prcElongum, of which, of course. E. Swartzii 

 is a subspecies, — while in the Savernake Forest localities they were 

 mvich smaller and very short and turgid. Mr. Knight tells me he 

 has noticed the same differences in tlie capsules in plants sent him 

 from the Pembrokeshire coast and those growing inland near Chel- 

 tenham. 



PlagiotTiecium silvaticum B. & S. 7, 8. In woods and rather 

 plentiful at the foot of shrubs in hedgerows near Great Bedwyn, 

 fruiting {teste Dixon) sparingly in a wood near Froxfield and also in 

 Savernake Forest. 



Hypnum aduncum group pseudo-fluitans var. paternum forma 

 gracile Ren. 8. In masses in a pool near Folly Farm ; this moss 

 affects pools on London Clay in this district. H. JJ 2d tans var, 

 qracile Boul. 7*. Very plentifully in and around a small pool on 

 London Clay at about 550 ft. in Chisbury Wood, Great Bedwyn. 

 Mr. J. A. Wheldon writes : — " The moss is apparently a rather 

 abnormal state of var. gracile Boul. It is really too young (or 

 badly developed owing to local conditions) to be a good example, and 

 shows a tendency to approach the var. Jeanhernati Ren. I think 

 the very slender nerve and alar cells are, however, more characteristic 

 of var. gracile, of which it may be looked upon as a depauperate 

 state." H.flidtans is an interesting addition to the North Wiltshire 

 moss flora in which calcareous vice-county it cannot be a common 

 plant, for it generally avoids lime, and Mr. Knight gives no record 

 for East Gloucestershire (v.c. 33) and only one (the \di.r. falcatum) 

 for West Gloucestershire (v.c. 34). H. palustre Huds. 7, 8. This 

 moss fruits freely by the side of the Kennet and Avon Canal near 

 Great Bedwyn. 



Hepatics, 



The following hepatics were also gathered around Great Bedwyn 

 in the winter and spring 1917-1918. Out of" 281 recorded species 

 the Census Catalogue of British Hepatics (1913) mentions only 

 11 species for North Wiltshire and IS species for South Wiltshire, 

 the Wiltshire liverworts, like the mosses, having been much neglected. 

 The comparative dryness of the county would probably militate 

 against a long list of these plants being produced. Miss E. Armitage, 

 who is cataloguing the hepatics of the more western county of 

 Hereford, tells me she is doubtful of obtaining so many as one 

 hundred species in her list. The Census Catalogue Wiltshire records 

 are due to Messrs. W. R. Sherrin and W. Watson, neither of whom 

 live in the county. Messrs. H. H. Knight and W. Ingham have very 

 kindly helped me with the following short list of twenty-one species
