290.^ASTRAGALUS/CAMPESTRIS, Linn. 



Area **^^**^*j^**j^j(=.4^15. 



South and North limits in Forfarshire. 



Estimate of provinces 1. Estimate of counties 1. 



Latitude 56 — 57. Highland type of distribution. 

 ^•/»-^/{'. Arctic region. Inferarctic zone. 



Descends and Ascends to about 700 yards. 



Range of mean annual temperature 41 or 40. 



Native. Rupestral. Extremely local ; being found 

 only on one spot, among the mountains in the north of 

 Forfarshire. Although thus restricted, there is a difBculty 

 in saying to which of the zones this species belongs ; since 

 Saxifraga nivalis has been observed rather lower, and 

 Corylus Avellana almost equally high as this Astragalus, 

 on the same range of rocks ; yet the inferarctic zone should 

 be interposed between the zones of the Corylus and Saxi- 

 fraga, as is the case in every other place wherein I have 

 seen them. See the remarks on this high locality for the 

 Corylus, in the present volume, page 42.
