Native. Rupestral. Mr. Borrer and Mr. Gibson 

 equally pronoimce this species quite distinct from H. 

 Lawsoni, after having seen it in the wild state and also 

 under garden culture. I have myself seen it living as a 

 garden plant only, but can now concur with their views. 

 As yet, it appears to have been certainly found only in 

 the two adjacent counties of York and Durham, that is, in 

 and about Teesdale. But Mr. Gibson reports H. Laj)ey- 

 rousii or cerinthoides as found in the neighbourhood of 

 Blair Athole, Perthshire (Phytologist iv. 05). Whether 

 or not H. iiicum descends into the agrarian region I am 

 unable to say, but likely enough this may be the case. 

 H. compositum (Lap.), from " Prats de MoUo, Pyr. orient. 

 Xatard. Aug. 1831," distributed by the Unio Itineraria, 

 diifers but little from the plant of Teesdale. (See vol, ii. 

 page 58.)
