252 THE JOUllNAL OF B0TA5fY 



neither inliers nor outliers of other geological formations. It is tme 

 that a considerable portion of the surface is formed of various gravels 

 but the gravel is much the same from the point of view of plant-life 

 as the Bagshot Sand itself ; the surface is, in fact, mainly sand and 

 o-ravel with subordinate beds of clay or sandy clay, and there is an 

 absence of lime in the area. 



In 1916 I had a few copies of my list of plants from this district 

 printed for the use of those interested, and a note on the Flora was 

 read to the Linnean Society and published in their Proceedings for 

 1915-16, p. 5 (see Journ. Bot. 1916, 94). I have since added some- 

 what to my list and, taking the 16th edition of the London Catalogue, 

 I have now marked 705 species, 43 varieties, and 8 hybrids as growing 

 on the Bagshot Sand ; 15 other species on Alluvium in the district, 

 and 83 species as recorded, but not, I think, established. This makes 

 a total of 854 entries. 



As I have said, the Bagshot of this area is mainly a sand formation, 

 and we should expect to find a i*esemblance in its Flora to that of 

 other similar formations in the south of England, and, in 'fact, most 

 of our plants do occur on the Eocene of the south coast as well as on 

 the Lower Greensand and Hastings Beds. The resemblance to the 

 Flora of the Lower Greensand is especially marked, but as that 

 formation contains beds of limestone, such as the Bargate Stone, we 

 find some species on it w^hich are absent from our area. The con- 

 ditions of plant-life are, however, so similar to those in other places 

 that I cannot name any species which is confined to the Bagshot 

 District ; still there are some plants which are distinctly characteristic 

 of our area. 



Ranunculus Lenormandi F. Schultz is described in Fl. Berks, 

 p. 14, as occurring only on th^ Bagshot Beds in that county, and I 

 have found it at several places on the Middle Bagshot Beds in both 

 the Berks and Surrey part of our District. It occurs on the Lower 

 Bagshot in a damp field by a small brook about a mile and a half 

 south of Wokingham and Mr. C. E. Britton tells me that it is found 

 on Esher Common, also Lower Bagshot. In Hampshire I found it 

 on the Yalle}" Gravel of the Black water at Yately ; this gravel is 

 . underlain by Bagshot Beds and is in the Bagshot District. The 

 Kev. E. F. Linton describes the species from the Dorset Bagshot 

 Beds (Fl. Bournemouth, p. 27), and it has been recorded from the 

 * Hastings Beds and Lower Greensand. In Brewer's Flora of Surrey^ 

 it is marked for the London Clay, pp. 4, 319, but I believe that to be 

 an exceptional occurrence. 



Hypericum JElodes L. is found in abundance in many of the lakes 

 and ponds of the district : I may mention Wellington College and 

 Chobham Common as examples for the Middle Bagshot and Ockham 

 •Common for the Lower Bagshot (see also Fl. Berks, pp. xli, 116; 

 Fl. Surrey, p. 47 ; Fl. Hamps. p. 70). It is common on the Bagshot 

 Beds of Dorset, and has been recorded from the Lower Greensand and 

 Hastings Beds, but is wanting on many geological formations. 



Hieracium is more abundant on the Bagshot Sand than on the 

 adjoining fonnations, and the species have not yet been fully 

 worked out. This applies more especially to the group Vulgata. My
