THE FLORA OF THE BAGSHOT DISTRICT 255 



Rhynchosjpora alha Valil is found on Chobham Common and near 

 Wellington College, and other localities will be found in the County 

 Floras. It is recorded as common in the Bournemouth District 

 (Headon Beds, Bagshot Series, Gravel) and as occurring on Lower 

 Ureensand and Hastings Beds. 



Schyusfluitaiis L. is found near Wellington College and at other 

 places in our district, and is recorded from Bagshot Beds, Headon 

 Beds, and Grravel of the south coast and also from Blackheath Beds, 

 Lower G-reensand, and Hastings Beds. 



Carex canesceiis is recorded from the Surrey, Berks, and Hants 

 parts of the Bagshot district, and I have specimens from Sandhurst. 

 It also is found on the Bagshot Sei'ies of the Bournemouth District 

 and on the Lower Grreensand at Beigate. I have specimens of a 

 pretty Sedge from Chobham Common and boggy ground near Broad- 

 moor very like C.Jlava var. Icpidocarpa Syme (E. Bot. t. 1673), 

 which is made a variety of C.Jlavu in the London Catalogue, Berks 

 (p. 550) gives C.Jlava var. minor from Bagshot Sand localities; this 

 is made a variet}'' of C. Oederi Betz. in the London Catalogue. In 

 Fl. Hamps. (p. 475) two species are given for the Bagshot District — 

 C.Jlava var. minor Towns, and C. Oederi Retz. Whatever the 

 correct nomenclature may be, I think that I may safely count two 

 species for the district. I may mention that King John's Bog, 

 Odiham, where ^oo({Jlava gemiina was found (Fl. Hamps.) is off the 

 Bagshot Sand, and is on wet Valley Gravel or Alluvium underlain by 

 London Clay. C.Jlava var. minor is recorded from the Bagshot 

 Series of the south coast, the Lower Greensand, Hastings Beds, and 

 also from Andover (Chalk), Keston (Blackheath Beds), below Cray- 

 ford (Valley Deposits), and Dungeness (Gravel). 



Carex binervis Sm. is abundant on our commons, more especially 

 on Middle Bagshot Beds. It is recorded from the corresponding 

 Series of Bournemouth, from the Headon Beds, Lower Greensand, 

 Hastings Beds, and from the Blackheath Beds of Keston, &c. 



Carex Pseudo-Ggperus L. is given amongst the plants of the 

 Bagshot Sand in Fl. Berks (p. xli). I have specimens from Ockham 

 Common and the Basingstoke Canal, but though it grows freely 

 enough where it occurs, I should call it a plant of the Alluvium 

 and Valley Gravel which has strayed into our district. It is described 

 as rather rare in Hants, but is more common in marshy places 

 in Kent. 



SPHAGNACEiE. 



Sphagnum is found in some abundance in a great number of 

 streams and bogs in the district ; the patches are not as a rule large, 

 but there is a considerable variety of species. Some of them 

 are given in Mr. Horrell's paper on the European SphagnacecB, 

 published in this Journal for 1900, with the localities Brookwood, 

 Pirbright, North Camp, and probably Aldershot, which are situated on 

 Bagshot Sand. I myself have chiefly collected from the Berkshire 

 part of the district ; my specimens have been kindly determined by 

 Mr. W. R. Sherrin, and I have added in the following list a few 

 species from Chobham Common, Surrey, communicated by him.
