tills variable var." — H. falcatum Brid. 7*. Bog in Hungerford 

 Marsh near the Bedwyn Brook. — H. Patientioe Lindb. 7*. Avery 

 small form on sandy clay in Chisbury Wood. — H. stramineum 

 Dicks. 7*. A form with spreading distant leaves grew submerged 

 very sparingly with H.fiuitans var. gracile in a pool which dries up 

 in the summer on peaty soil at about 550 ft. in Chisbury Wood. — 

 H. giganteum Schp. 7*. Very sparingly in Hungerford Marsh 

 growing with Mniiim a fine var. elatum : this is probably a relic 

 of a time when Hungerford Marsh was in a much wetter and more 

 undrained condition. 



Hepatics. 



Siccia hifurca Hoffm. 7*, 8*. Sparingly on rides in Chisbury 

 and Bedw^ai Brails Woods {teste Nicholson) ; the Census Catalogue 

 records it from only seven vice-counties. R. commutata Jack. 7*. 

 Plentiful in a stubble field by the London and Bath Koad near Frox- 

 field with R. sorocarpa and R. glauca. — R. glauca L. 7*. Stubble 

 field near Froxtield, also in Savernake Forest. R. sorocarpa Biseh, 

 7*, 8*. Not uncommon on damp earth throughout the district, easily 

 recognized by its bluish-green colour and deeply-furrowed frond. 



Conoceplialum conicum (L.) Dum. 8. Very fine on the brick- 

 work of a sluice near Shalbourne ; on brickwork inside the Bruce 

 Tunnel on the K. and A. Canal at Savernake. 



Pellia Fahhroniana Baddi. 7, 8. Common on damp ground, 

 and in very wet places throughout the district ; this species generally 

 affects calcareous soil ; the furcate apices of the thallus are a con- 

 spicuous character in autumn and winter. 



Fossombronia pusilla (L.) Dum. 7*, 8. Plentifulon the insides 

 of a cart-rut and in other places in Chisbury Wood ; also in Fox- 

 bury Wood. — F. Wondraczekl (Corda) Dum. 7*. Chisbury Wood 

 and on damp clay by the side pool near the Column, Savernake 

 Forest. — F. Hicsnoti var. anglica Nicholson. 7*. In considerable 

 quantity on sandy clay upon rides in Chisbmy Wood; very rare 

 plant \ confirmed by Mr. Nicholson. — F. Crozalsii Corb. 7*. A 

 plant bearing a single capsule on sandy clay soil in Chisbury Wood ; 

 Mr. Nicholson writes : — " Mr. Macvicar seemed to be quite satisfied 

 about the Foss. Crozalsii, so I think you would be justified in record- 

 ing it. I am inclined to agree with Mr. Macvicar that it is rather 

 close to F. Womlraczeki. F. Crozalsii was recorded by me as a 

 British plant from the Lizard in Journ. Bot. 1917, p. 10 ; the iden- 

 tification was confirmed by M. Douin, but the plant was not quite 

 typical, and your plant agrees better with the type than mine." 



Marsupella Funckii (Web. et Mohr.) Dum. 7*. In fair 

 quantity in one place, Cobham Frith Wood, near Knowle Fai-m, 

 Savernake. 



Alicularia scalaris (Schrad.) Corda. 7*. Heathy ground in the 

 north part of Tottenham Park. 



Gymnocolea inflata (Huds.) Dum. 7*. In some quantity in 

 one place on heathy ground in the north part of Tottenham Park.

 a chalk-pit by a roadside near Kamsbury. — L. hicrenata (Schmidt) 

 On sandy ground on a ride near the Column. Tottenham
