416 73. ORCHIDACE^. 



Mr. Coleman's habitat for the plant, in Somerset, is more 

 elevated, being " near the summit of Dimkery, a hill of 

 1668 feet, about seven miles south-west from Dunster." 

 In Shropshire, it occurs on the Stiperstones Hill. The lo- 

 calities in the provinces of North Wales, Trent, and Mersey, 

 are on hills or elevated ground. Some of those in York- 

 shire, perhaps, may not be 100 yards above the sea-level. 

 Coddon Hill can scarcely be considered to exceed the in- 

 feragrarian zone. My notes of localities indicate autho- 

 rities for the occurrence of this species in 34 counties, and 

 it will probably be found in some few others, for which I 

 find no records at present, as Shetland, Hebrides, Caith- 

 ness, Dumbarton, &c.

Native. Sylvestral. Possibly the estimate of 75 coun- 

 may be a step too high in the scale ; but it is difficult to 

 select half-a-dozen, from which this species is likely to be 

 quite absent. Devon is named in the " south limit," from 

 the want of any record of the plant for Cornwall ; but I 

 have seen it in the extreme west of Devon, if not actually 

 within Cornwall.
