Whether there may also be a third species in the fen is at 

 present doubtful. V. canina L. emend. Echb. is essentially a plant 

 of dry SLindy soils unlikely to be present, and the var. hLCorum may 

 perhaps be really a form of V. Buppii. V. SchuUzii, V. stricta and 

 other forms to which names have been given appear to be matched 

 by plants collected in the fen, but their true nature, whether 

 hybrids or varieties, has yet to be determined. They grow on the 

 continent in a similar manner with F. stagnina and V. Buppii, and 

 considering the fact that all sorts of intermediates in respect of 

 any character can be found in the fen, it is difficult to say where 

 the limits of V. Buppii and its varieties and conditions can be 

 drawn as distinct from the hybrid forms; 



Since it is difficult to fix the hmits of F. Buppii it is not easy to 

 say exactly how it differs from V. canina, but V. Buppii is to be 

 distinguished especially by its habitat ; peaty fens as opposed to 

 dry sandy soils. It is erect when well grown, though decumbent 

 when dwarf. The stipules are green and leafy, larger than those 

 of V. canina, about |-| the length of the petioles in the upper 

 middle leaves, and sometimes equalHng them in the upmost 

 leaves. They vary much in size, perhaps owing to crossing 

 with V. stagnina. The petioles are longish, equalling to exceeding 

 the laminae when fully grown, and winged above. The laminae are 

 cordate-ovate and blunt, varying from fleshy in the dwai'f plants 

 to very thin in the plants much drawn up in rank grass. They 

 are sometimes elongated, again perhaps owing to crossing with 

 F. stagnina. The flowers are borne on long peduncles and are 

 large and broad as in F. Biviniana, but are pale bright blue in 

 colour. The spur is rather slender, greenish, two or three times 

 as long as the calyx appendages. The capsule is acute. 



It was also gathered in Cambridgeshire in the fens around 

 Chatteris by Fryer, and should be looked for in suitable localities 

 elsewhere, where it may have been passed over as F. canina. 



COUNTY LISTS OF MOSSES. 



By C. p. Hurst. 



In recording the following mosses, the nomenclature and 

 arrangement of the Census Catalogue of British Mosses (1907) 

 have been followed, and of course the old county boundaries have 

 been adhered to. The number or numbers appended to^ some of 

 the mosses indicate the vice-county or vice-counties in which 

 they have been observed. I am greatly indebted for notes and 

 assistance to Messrs. H. N. Dixon, H. H. Knight and J. A. 

 Wheldon, and also to the Marlborough College Natural History 

 Society and Mr. Dixon for kind permission to make a long extract 

 from the latter's very interesting article, " The Moss Flora of the 

 Marlborough Grey wethers," pubhshed in the Beport of the Marl- 

 borough College Natural History Society for 1907, pp. 28-30, and 

 reprinted in The Wiltshire Archceological aitd Natural History
