red radicles and at the margins of the rock-pools below forms a fringe 

 of very graceful slender plants with less tomentum. — F. adiantoides 

 Hedw. Frequent in a variety of situations, as boggy patches on 

 cliffs at St. Agnes (1), tops of hedge-banks at Polperro (2) and 

 damp rock faces : in the last it usually fruits freely, as at Polperro 

 and St. Keyne (2). — F. decipiens De Not. Not common ; I have 

 found it only at Lambriggan (1) at the bases of tree-trunks. — 



F. taxifoUiis Hedw. c.fr. near Looe ; usually barren. 



Grinimia maritima Turn. Abundant on rocks by the sea at 

 St. Agnes (1) and Polperro (2). — G. trichophylla Grev. c.fr. at 

 Idless near Truro (1), and at Broadoak and Helman Tor (2). — 



G. mhsriunrroiia Wils. Rocks on hillsides, Polperro (2). The 

 species evidently intergrades A^ith G. frichophylla, Mr. C. P. 

 Hurst tells me that some plants I sent him from Polperro were 

 shown by hiiu to Mr. Dixon who pronounced them exact inter- 

 mediates between G. trichoplu/Ua and G. subsqitarrosa. 



Mliacomitriam aciculare Brid. Common on rocks, but occurs at 

 Tresawzen (1) in boggy ground. — H. protensum Braun. Plentiful, 

 c.fr. on rocks on Cheesewring and neighbouring tors and at St. Cleer (2). 

 — B. fasciculare Brid. Rock face at Trelawne (2). — H. lietero- 

 stlchum Brid. Plentiful, c.fr. on granite at St. Cleer and on Cheese- 

 wring Downs (2). — R. laniiginosmn Brid. More or less sparingly in 

 most of the wet peaty moors near St. Agnes and Perranporth (1), 

 but always, I believe, barren. Plentiful and frequently c.fr. on 

 granite in Draynes Valley and near Cheesewring (2). — B. canescens 

 Brid. Frequent ; usually beside ])aths and roads on peaty ground. 



F ty cliomit r ill m poll) pliylhim Fiirn. Rejerrah near Perranporth 

 (1). Liskeard, Polperro, Bodmin Moors (2J, common. Much com- 

 moner in v.c. 2 than in v.c. 1. 



Hedwigia ciliata Ehrh. c.fr. on granite at Mabe near Pen- 

 ryn (1). Cliffs near Polperro ; Helman Tor (2). 



Fottia recta Mitt. Lambourne near Pen-anporth (1) ; Pol- 

 perro (2) ; not infrequent. — F. crinita Wils, Shore between Looe 

 and Polperro (2). 



Tortilla aloides De Not. Perranzabuloe (1) ; Polperro (2). 

 Common. — T. Icevivila Schwseg. var. IcBvipilceformis Limpr. Idless 

 near Truro; Lambriggan near Perranporth (1) ; Lansallos, Polperro, 

 Talland (2). All the Cornish plants I have seen have either the 

 leaf structure or foliose gemmae of the varietj^ and most agree in both 

 respects. Possibly typical T. Icdvipila may not occur in Cornwall. 

 Where capsules are abundant, as at Idless, gemmae are scarce. — 

 T. ruralis Ehrh. On slate roofs near Polperro ; uncommon in Corn- 

 wall. — T. ruraliformis Dixon. Perranporth Sandhills (1) abundan-t ; 

 fruit very sparingly produced. 



Barhitla lurida Lindb. Wall at Polperro (2). — B. topliacea 

 Mitt. On masonry at Perranporth (1) ; on calcareous matter on 

 rock face, Polperro (2). — B. cylindrica Schp. Polperro and Tre- 

 lawne (2), frequent. 



Weisia verticillata Brid, Encrusted with calcareous matter on 

 cliffs at Perranporth (1) and at Lansallos (2). On old lime kilns near 

 Polperro and Looe (2).
