THE LAKE FLORA. 
By THE Rev. W. TUCKWELL, M.A. 
(Read at Ambleside. Inadvertently omitted from the last Number. ) 
For botanical purposes the Lake District is bounded on the east 
by the river Lune, so far as to Low Gill station, thence, as far as 
Penrith, by the Lancaster and Carlisle railway ; on the north by a 
line loosely drawn from Penrith to Allonby through Wigton; on 
the west by the Irish Sea; on the south by Morecambe Bay ;— 
containing mountain, moor, plain, river, lake, sea-shore, bog ; 
including in its geological formation igneous rock, slate, Old-and 
New Red Sandstone, Mountain and Magnesian Limestone—it 
presents all the conditions of a rich and varied flora. 
Of the 1430 wild plants recognised as British, aboriginal or 
introduced, about goo are found in the Lake District. Of these 
eleven only are strays from eastern England; twelve only from 
western England; no less than two hundred ascend from southern 
England; all the rest are either general in their distribution 
throughout our island, or have their head-quarters in Scotland and 
in northern England. 
You are aware that the prevalence of particular floral types is 
largely influenced by height above the sea. The majority of your 
Lake plants grow to goo feet, at wnich point the Blackberry, Crab, 
Alder, Gueldres Rose, Bay Willow (\S. fragilis) cease to thrive, 
arable cultivation becomes rare, and inhabited houses are few. 
Scattered farmhouses there are even at a height of 1800 feet,
