336 Mr. Winch on the Geography of Plants. [May, 



1 . Those plants which have reached their northern limits in 

 this part of the kingdom. 



2. Such as have reached their southern limits. 



3. Those that are found on the sea coast, and again among 

 the mountains. 



4. Rare species natives of Switzerland. 

 5. of Lapland. 



6. of both those countries. 



7. of neither of those countries. 



8. Oleraceous plants found in a natural state. 



9. Species which are become indigenous, though originally 

 imported from a distance. 



1 . Plants which have reached their northern Limits. 



Bupleurum tenuissimum. On Seaton Moor, near the mouth of 

 Tees. 



Juncus maritimus. On the sea shore, near Seaton. 



Ruinex aquaticus. Near Preston in Skirn, and at Polam. 



Schaenus Mariscus. At Hell Kettles, near Darlington. 



Butomus umbellatus. (See Lightfoot's Flora Scottica, vol. ii. 

 p. 1139.) In the river Skirn, near Darlington. The above 

 mentioned places are all situated in the lower part of the vale 

 of Tees, and at an inconsiderable elevation above the level of 

 the sea. 



On the magnesian limestone which skirts the coast of Durham, 



are to be found 



Cypripedium Calceolus.* "i T ,, , , . • , .

Uphrys muscuera. V C tl FH 



Serapias ensifolia. J 



Ophrys apifera. Reaches a little further north to the vicinity of 

 Ryehope and Monkwearmouth. 



Tamus communis. Terminates its long range from the kingdom 

 of Algiers (see Smith in English Botany) on the north bank 

 of the river Wear, above Sunderland. 



Taxus baccata. Is quite at home on the limestone cliffs in Castle- 

 Eden, and I greatly doubt if it be indigenous further north. 



Hedysarum onobrychis, Saintfoin. Grows wild about Hart- 

 on Down Hill and Ryehope. A hint the farmers of that neigh- 

 bourhood do not benefit by, though they cultivate a sterile 

 calcareous soil. 



Hippocrepis comosa. On Cronkley Fell, at an elevation of above 

 '■ 2,000 feet. 



Statice Limonium occurs sparingly on the muddy shores by the 

 mouth of the Tees, by the Wear above Hilton, and on the 

 coast opposite Holy Island, in Northumberland ; but does not 

 reach the east coast of Scotland, though it is found on the 

 Mull of Galloway, on the west coast. 



* This locality was noticed above 40 years since in Stephen Robson's British 

 Flora. It still continues to grow in the same place, though by no means abundant.
