8 THE JOURNAL or BOTANY 



as Curnow (Holmes & Brent, op. cit.) records it for Trungle Moor. 

 Its distribution in the British Isles, as indicated by the figures 

 of the Census Cataloguey appears to coincide with that of the 

 Priuiarj'' rocks, hence its occurrence in Cornwall was to be expected. 

 —R. Schreberi Willd. Chyverton (1) ; Upper Fowey Valley (2). 



Hepatic s. 



!Riccia sorocatpa BIsch. Frequent on earthy banks above clifFs 

 at Polperro (2). In spite of careful search I have not been able 

 to find any other species. 



Cunoceplialum conicum (L.) Dum. Grows finely on wet banks, 

 especially in deep shade, but is usually barren ; c.fr. at Penwartha (1). 



Lunidaria cruciata (L.) Dum. Common ; on damj) rock-faces 

 near Polperro as well as in its usual artificial habitats. 



Marchanfia polymorplia L. With 6 receptacles in old mine- 

 workings at Perranporth (1) ; on stones in stream, Talland (2) : 

 a much less common plant than Conoceplialiim conicum. 



Aneura pinguis (L.) Dum. Common in bogs in West Corn walk — ■ 

 A. muJtiJida (L.) Dum. Yentongimps and Tresawzen Moors (1). — 

 A. major (Lindb.) K. Miill. In the Perranporth district (1) this is 

 possibly the commonest form of Aneuray occurring in wet ground and 

 on moist banks. Near Polperro (2) it occurs under similar conditions 

 but is much less frequent. By a damp pathway across A'entongimps 

 Moor (1) I have gathered a densely tufted j^lant which Mr. Jones 

 refers to this species. The Census Catalogue gives no record for the 

 West of England. 



Metzgeria furcata (L.) Dum. Common on trees. Plants on 

 rock-faces near Polperro have the large cells and general api->earance 

 of M. conjugata, but I have not been able to find monoicous 

 inflorescence. 



Fellia epipliglla (L.) Corda. Common on loamy banks and by 

 streams. Very fine and handsome on clay banks at Yentongimps 

 and elsewhere in v.c. 1. — P. Fahhroniana Raddi. Perranporth (1); 

 base of damp wall by rivulet at Talland (2). 



Blasia pusilla L. Goonhaven Moor near Permnporth (1). 



Pefalophi/Uum RaJfsii (AV'ils.) Gottsche. Damp hollow between 

 sand-dunes, Perranporth (1). 



Fossombronia pusilla (L.) Dum. Lambriggan and Callestick (1) ; 

 Polperro, frequent ; Boconnoc (2) ; almost invariably on earthy 

 patches of hedge-banks. — F. WondraczeJci (Corda) Dum. Damp 

 side of path across Silverwell Moors (1). — E. ccespififormis De Not. 

 Mouths of rabbit burrows and earthy patches adjoining in hilly field, 

 Polperro (2). — F. Dumortieri (Hiib. et Genth.) Lindb. On peaty 

 ground, Goonhavem Moor(l). Apparently also on similar ground at 

 Trenode (2), but I have not yet found mature capsules. This is not 

 recorded for the West of England in the Census Catalogue, its area 

 of distribution com])rising only Surre}' and Sussex in the south of 

 England, one county (Carnarvon) in Wales, Lancashire, Yorkshire, 

 and Cumberland in the north, and five vice-counties in Scotland. — 

 F. angulosa (Dicks) iladdi. Rocky slopes above the cliffs, St. 

 Agnes (I).
