480 80. ALISMACE^. 



Ascends to 950 yards, in East Highlands. 



Range of mean annual temperature 52 — 37. 



Native. Paludal, Uliginal. I have seen this species 

 up to 600 and 700 yards, in several places in Scotland, 

 but only in two spots above 800 yards. It rather affects 

 the shore, along with T. maritimum ; and thus makes a 

 sort of approach to the character of a littoral plant. 



1117. SCHEUCHZERIA PALUSTRIS, Linn. 



Area ***^5**89 10***i^l5. 



South limit in Salop, Notts, Chester, York. 



North limit in Perth. 



Estimate of provinces 5. Estimate of counties 6. 



Latitude 52 — 57. Scottish type of distribution. 



Agrarian region. Inferagrarian — Midagrarian zones. 



Descends nearly to the coast level, in Severn. 



Ascends to 100 or 200 yards, in England. 



Range of mean annual temperature 49 — 48. 



Native. Paludal. This very local plant was long sup- 

 posed to be restricted to a single English county ; but its 

 area and census have been gradually extended to the five 

 provinces and counties above indicated, although still 

 known only in very few separate localities. The Rev. 

 George Pinder kindly sent me a specimen in illustration 

 of his lately discovered locality in Cheshire ; and I learn 

 from the Rev. M. J. Berkeley, that it has also been found 

 in the north of Nottinghamshire.
