stinction, though it is a permanent variety, unaltered when pro- 

 pagated by seed. 



A specimen from Villars himself of his H. pulmonarioides ac- 

 cords in every particular with this variety, except that it is not 

 above half so tall, and its calyx and flower-stalks are rather 

 more abundant in black prominent glandular hairs, both cir- 

 cumstances to be attributed probably to its being a wild speci- 

 men. I have thought it safest however to quote this excellent 

 author with a mark of doubt. My plant has no affinity to 

 11. amplexkaule^ with which he compares his. 



To this writer I am obliged for occasioning me to stumble 

 upon the plant of Dillenius, t. 149, which Villars cites under 

 ceri?ithohks, certainly without any propriety, but which I con- 

 fess myself, like my predecessors, to have hitherto overlooked or 

 left undecided in despair. Dillenius refers it, with doubt, to 

 Kay's //. macrocaulon hirsutum folio rotundiore, which is certainly 

 II. marorum of Linnaeus as above mentioned. This plant of 

 Dillenius, found by Richardson, cannot be referred to that spe- 

 cies, on account of the lanceolate and decurrcnt form of its ra- 

 dical leaves, and especially the manner in which they are tooth- 

 ed ; not to mention its more leafy stem ; in all which points it 

 agrees with sylvaticam. Yet its " glaucous leaves and pale yel- 

 low flowers" do not suit either variety of the syhatkum. This 

 plate of the Horhts Elthamcnsis is one of the very few left un- 

 marked by Linnaeus in his own copy of that work. It is surely 

 the II. Lawsoni of Villars, of which I have a Pyrenean speci- 

 men, gathered by Mons. de St. A mans, and given me by the 

 Rev. Mr. Kirby, seemingly authentic. Villars considers this as 

 //. leptocaulon hirsutum folio longiore of Lawson and Ray, which 

 Ave have just found so much difficulty in determining, and, if 

 right, he has cleared up a \ery difficult question for us British
