A HISTORY OF BUCKINGHAMSHIRE 



Gibbon in the Thame district. R. obtusifolia occurs in the Thames and 

 Colne districts, and on the chalk escarpment both in the Ouzel and 

 Thame drainage, and it grows at Lillingstone in the Ouse district, and the 

 var. tomentella is also found. 



R, canina as lutetiana is the commonest and most generally distri- 

 buted form, and the var. Andegavensis occurs at Chalfont, etc. Another 

 widely distributed and common rose is R. dumalis, the R. sarmentacea of 

 Forster. R. dumetorum and the var. urbica is also widely spread. R. 

 verticillacantha is local, but it occurs at Marsh Gibbon and Chalfont. R. 

 Deseglisei is found at Beaconsfield, R.g/auca grows near Brill, and the var. 

 subcristata at Swanbourne, but these sub-erect plants are very rare in the 

 south of England. R. stylosa is very local in the north of the county, 

 but there are some fine bushes about Brill ; but near Beaconsfield and in 

 the country towards Penn and Chalfont it is very common, and some 

 large plants are also to be seen between Lane End and Medmenham. R. 

 arvensis is a very common rose on clay, and is especially frequent in 

 woods on stiff soils. The downy-leaved rose (R. mollissima, Willd., the R. 

 tomentosa, Sm.) is not unfrequent in dry soils in hilly districts, as at Brick- 

 hill, and more frequently on the southern slopes of the chalk where the 

 var. subglobosa, Sm., var. scabriuscula (Sm.) and var. syfoestris (Lindl.) have 

 been noticed. At present I have no authentic record of R. villosa, L., the 

 R. tnollis, Sm., in the county. 



THE MOSSES (Musci) 



The moss flora of Buckinghamshire is but very imperfectly known, 

 but it is probably much richer than Oxfordshire, since the Brickhill 

 district certainly yields a large number of species. The woods of Penn, 

 and the neighbourhood of Dropmore, Burnham Beeches, Stoke Common, 

 Fulmer, Black Park, Gerrard's Cross, the wet woods near Tilehouse 

 Denham, are all places which would well repay the bryologist for 

 exploring. 



For the following notes I am especially indebted to Mr. E. M. 

 Holmes, F.L.S., who is a native of the county, being born at Wendover, 

 and Mr. John Benbow of Uxbridge, who has done so much in exploring 

 the botany of the county of Middlesex.
