indicated for it ; as also the county of Durham. Othei^wise, 

 it is restricted to the southern and south-western coasts, as 

 far as my compilation of localities can show those which 

 have been reported for it. The genus Daucus requires a 

 veiy careful revision; and it is likely that even our only 

 two native species are frequently confused one with the 

 other. 



f^^. /^.^,A^ 491. Caucalis daucoides, Linn. 



Area 1 (2) 3 4 5 * * 8 * 10 11. 



South limit in Kent, SuiTey, Somerset. 



North limit in Durham and Yorkshu'e. 



Estimate of provinces 7. Estimate of counties 15. 



Latitude 51 — 55. Gennanic tj'pe of distribution. 



Agrarian region. Inferagi-arian — Midagi-arian zones. 



Descends nearly to the coast level, in England. 



Ascends to 50 or 100 yards, in England. 



Range of mean annual temperatui'e 49 — 48. 



Colonist. Agrestal. Apparently introduced by agricul- 

 tural operations, and possibly also through ballast. Is it a 

 permanent weed of com-fields in Somerset, or only a tem- 

 porary introduction ? That coiuity is the only one in the 

 Peninsula, for which I find a habitat of this species on re- 

 cord. In the Channel, too, I am aware of only a single 

 and much-to-be-suspected locality; namely, " about an old 

 lime-kiln at South Haven " (Salter's Botany of Poole) .
