THE FLOEA OF THE BAGSHOT DISTEICT 253 



specimens have been kindly looked over by the Eevs. E. F. Linton 

 and E. S. Marshall. Some from Wellington College are placed near 

 H. grandidens Dahlst. or H. serrati^rons var. lepistoides Johan. ; 

 one from the same place and one from Finchampstead Eidges are 

 near H. surrejanum F. J. Hanb. ; one from St. Sebastian near 

 Wokingham is named H. pinnatijidum var. vivarium Lonnr. ; two 

 from Wellington College are described as H. scanicum or a form near 

 it ; one fi-om AVellington College and one from Broadmoor are 

 assigned to H. sciapliiliiin Uechtr. ; and one from Finchampstead to 

 H. sciapliilum var. fransiens. Mr. Linton considere that a number of 

 my specimens from Wellington College belong to an midescribed 

 species, for which he proposes the name H. euryphyllum. 



There is less difficulty as to the species in the other groups (see 

 Fl. Berks, pp. 312-315), but I may mention that I have found 

 H. tridentafum var. setigerum Ley at Wellington College and var. 

 acrifolium Dahlst. at Gracious Pond Farm, Woking, and on Wey- 

 bridge Common, Surrey. From the Valley Gravel of the Bagshot 

 District I have H. rigidum Hartm. from Sandhurst, Berks, and 

 Walton Common, Surrey, and H. umhellafum var. coronopifoliiuii Fr. 

 from Sandhm-st. 



Vaccinium My rt ill us L. is a plant of the Bagshot Sand, Lower 

 Greensand, Hastings Beds, and other sandy formations. In the 

 Bagshot District there are many patches of this plant in what were 

 woods of JPinns sylvestn's, both on the Bagshot Sand and the Plateau 

 Gravel. Many of these woods have now been cut down, and I am 

 curious to see how the Vaccinium will thrive. 



Gentiana Pneumonanthe L. is given by Brewer (Fl. Surrey, 

 pp. 150, 332) as occurring only on the Bagshot Sand in that county, 

 and the two localities given in FL Berks (p. 342) are probably on the 

 same Formation. It is frequent on the corresponding series in Dorset 

 (Fl. Bournemouth, p. 150). In Townsend's Fl. Hamps. (p. 258) it is 

 recorded from Hook Common ; this is near Odiham, and is an 

 interesting example of the transgression of the Bagshot Sand plant 

 on to Plateau Gravel, which rests on London Clay. It is about half 

 a mile S.E. of the nearest Bagshot outlier at Newnham and a mile 

 and a half from the main mass of the Bagshot Sand. Specimens from 

 this locality Avere given me by the late Miss Cole a few years ago. 



Euphrasia is characteristic of the Bagshot Sand ; Mr. Dunnis 

 Lumb has been good enough to look over m}^ specimens and. deter- 

 mines them as follows : — E. Rosfkoviana, Hayne is the most frequent 

 species ; I have exam])les from Wellington College, the East Berks 

 golf links, Birchen Inhams farm near Wokingham, and from East- 

 hampstead Moor, all in Berks. I also found it on the Valley Gravel 

 at Yately, Hants. E. hrevipila Burnat & Gremli occurred at 

 Wellington College some ^^ears ago. E. nemorosa var. ciliaia is 

 frequent at the same place, and E. gracilis Fr. I have from 

 Wellington College and from the Valley Gravel at Cox Hill Green 

 near Chobham, Surrey ; Mr. C. E. Britton tells me that it occurs on 

 Ockham Common. 



Myrica Gale L. is abundant in many parts of the Bagshot 

 District, and Mr. Hautneville Cope showed me a valley near Bramshill
