87. FILICES. • 265 



Nottingham, Forfar. The provinces above indicated for 

 the area by their Nos., rest on the following authorities : — 

 Peninsula (Mr. Eobert Withers !), Channel (Dr. Bromfield), 

 Thames (H. C. Watson), Ouse (Mr. James Paget ! Mr. S. 

 P. Woodward !), Severn (Eev. W. A. Leighton), South 

 Wales (Mr. Gutch, &c.), North Wales (Mr. J. E. Bowman), 

 Trent (Dr. Howitt !), Mersey (]\Ir. William Wilson), Hum- 

 ber (Mr. Tatham, &c.), Tyne (Mr. Embleton), Lakes (Eev. 

 George Pinder ; Hutchinson), Forfar (Mr. Maughan !). 

 These authorities appear sufficient to establish the several 

 provinces. Further, two localities are given for L. The- 

 Ij^teris in the Flora of Shetland, which are viewed with 

 distrust, while the species remains unknown between 

 Shetland and Forfar. 



1386. Lastrea Oreopteris, Presl. 



Area general. 



South limit in Cornwall, Isle of Wight, Kent. 



North limit in Shetland, Hebrides, Sutherland. 



Estimate of j)ro\inces 18. Estimate of counties 75. 



Latitude 50 — 61. British type of distribution. 



A. A. regions. Inferagrarian — Midarctic zones. 



Descends to the coast level, in the Peninsula. 



Ascends to 950 yards, in East Highlands. 



Eange of mean annual temperature 51 — 37. 



Native. Ericetal, Sylvestral. Eecorded from 60 coun- 

 ties or upwards; but rather doubtful whether 75 or 80 

 would be the better comital estimate. It is worthy of 

 note that a species so widely and generally distributed, 

 and the stations for which may be considered countless, 

 should have been classed among the rarer plants by 

 Turner and Dillwj'n, in the original Botanist's Guide.
