318 ADDITIONAL SPECIES, ETC. 



Ascends to 100 or 200 yards, in England. 



Range of mean annual temperatui'e 52 — 46. 



Native. Glareal or Rupestral. The distribution of C. 

 hirsuta can be described apart from that of C. sylvatica 

 still only imperfectly. Both would appear to grow in the 

 Hebrides (Balf. and Bab.) ; one only (but which really ?) 

 in Shetland, recorded as "C. hirsuta" by Edmondston. 

 Mr. Sjme thinks true C. hirsuta perhaps introduced to 

 Orkney. In the above widely extended area and census, 

 it will be understood that true C. hirsuta is stiU partially 

 confounded or combined with C. sylvatica. I have my- 

 self traced it from Devon northward to Perth ; and beyond 

 this range or area, I go by the use of the name, without 

 certainly knowing what botanists intended thereby. (See 

 vol. i. page 138.) 



86, b. Cabdamine sylvatica, Link. 



Area general ? 



South limit in Devon, Isle of Wight, Kent. 



North limit in Hebrides, ? 



Estimate of provinces 18. Estimate of counties 80. 



Latitude 50 — 59. British type of distribution. 



A. A. regions. Inferagrarian — Midarctic zones. 



Descends to the coast level, in the Peninsula. 



Ascends to 1000 yards, in East Highlands. 



Range of mean annual temperature 52 — 37. 



Native. Sylvestral, Paludal. It will probably be found 

 that this form or species is more widely distributed than 

 the C. hirsuta of dry places ; although in books the name 

 of the latter is more frequently used, meaning one or both 

 of the apparent species, often without any clear indication 

 which of them is intended. (See vol. i. page 138.)
