BOTANY 



Molton, Exeter, Honiton and Torquay botanical districts. The wood 

 horsetail (E. syhaticum) is not very common ; it has been recorded from 

 the South Molton, Honiton and Plymouth districts ; Moyle Rogers did 

 not see it in the Devon parts of the upper Tamar country and remarked 

 on its absence. The water horsetail (JB. limosum) is found in most of the 

 districts ; the variety jE. fluviatile also occurs not less commonly. £. 

 variegatum is rare in the county, but it occurs in the Barnstaple, Honiton 

 and Torquay districts. The Dutch rush (£. hyemale) has been reported 

 from the Honiton district, but possibly in error. 



LYCOPODIACEiE 



The following species occur in the county : — 



Lycopodium claratum, L. L. inundatum, L. L. Sekgo, L. 



The common club-moss (L. clavatum) is rather rare and local ; it 

 grows in a few stations in the northern parts of the Barnstaple and 

 South Molton botanical districts ; it is reported also from Haldon, the 

 Blackdown Hills, Ugborough Beacon and Dartmoor. 



The marsh club-moss [L. inundatuni) is rare and local ; there are 

 satisfactory records for it in the Barnstaple, Honiton, Torquay and Ply- 

 mouth botanical districts. 



The fir-moss is also local ; it has however been found in all the 

 botanical districts except Torrington. 



SELAGINELLACEiE 



Selaginella selaginoides. Gray (the prickly club-moss) has been re- 

 corded from Dartmoor and from Trentishoe Down in the Barnstaple 

 botanical district, but both these records require confirmation. 



MARSILEACEiE 



The pillwort or pepper grass [Pilularia globulifera, L.) was recorded 

 in 1797 by Polwhele as occurring on Blackdown; it has occurred also 

 near Lympstone, according to Jones and Kingston (F/. Dev. ii. iii) on 

 the authority of Miss Filmore. 



MUSCI {Mossesy 



The Moss Flora of Devonshire differs from that of the neighbour- 

 ing county of Cornwall, chiefly in the absence of a few species of a 

 distinctly southern type, such as Pbilonotis rigida, Hookeria laetevirens, and 

 Fissidens serrulatus, whilst on the other hand it includes many species of 

 a distinctly subalpine type that have not been recorded for Cornwall. Of 

 these the following may be mentioned : — Tetradontium Brownianum, 

 Catharinea crispa, Cynodonttum polycarpum, Cynodontium virens, Blindia acuta, 

 Dicranoweissia crispula, Dicranum spurium, Orthotrichum Hutchinsiae, Grim- 

 mia Donniana, Grimmia Hartmanni, Grimmia montana, Grimmta ovata,
