not accord tliereTvith ; but if such be the case in the six- 

 teen-mile radius of the Edinburgh circuit, it is a solitary 

 and remarkable exception. The species is omitted from 

 the Flora of Moray, and only a single locality is given in 

 that of Aberdeen. But in Murray's Northern Flora, two 

 Moray locaHties are recorded on the authority of Mr. 

 Stables, and one locality in Aberdeenshii'e, suspected to 

 be artificial. My herbarium has specimens from Foi-far, 

 Perth, Edinbiu'gh, Lanark, and counties to the southward 

 of these.

Area general. 



South limit in Cornwall, Isle of Wight, Kent. 



North limit in Shetland, Orkney, Hebrides. 



Estimate of i^rovinces 18. Estimate of coimties 82. 



Latitude 50 — 61. British type of distribution. 



A. A. regions. Inferagrarian — Inferarctic zones. 



Descends to the coast level, in the Peninsula. 



Ascends to 500 yards, or uj)wards, in East Highlands. 



Range of mean annual temperatui-e 52 — 41. 



Native. Paludal. Professor Dickie reports this grass 

 up to 2200 feet in Aberdeensliii'e ; which is not improba- 

 ble, though I have not myseK found it within 050 feet of 

 that altitude. I am at a loss whether the Glyceria hybii- 

 da or pedicillata (Townsend) should be placed under 

 this species, or under its too close ally G. x)licata : Mr. 

 Babington refers it to the latter.
