ardent admirer and cultivator of flowers in Dundee. After its intro- 

 duction by Mr. Lennox, it extended itself considerably and became 

 firmly established, although it has since been destroyed at one of the 

 stations, viz., the Dudhope station, as before mentioned, in conse- 

 quence of improvements. Although the origin of the Invergowrie 

 Mimulus is thus clearly shown, and every doubt set aside as to its 

 mode of introduction, by which it is seen that it owes its original ex- 

 istence entirely to mankind, yet I am not the more prepared on that 

 account to consent to its being discarded from our list of introduced 

 species ; for it does not now by any means depend upon mankind in 

 the least degree for the maintaining its existence, being quite natu- 

 ralized, even in defiance of the ambiguous Woodwardian definition 

 of the term. 



Regarding Eschscholtzia crocea, if Mr. Woodward means, in the 

 sentence T have quoted, to insinuate that I endeavoured to get that 

 plant pushed into notice as a native, I would beg to direct his atten- 

 tion to p. 136 of the present volume of the ' Phytologist,' where I re- 

 mark in regard to it and the Eutoca, in the very same paragraph as 

 I mention their occurrence, " These have undoubtedly no claims to 

 be considered as natives." Perhaps, however, some one else (at 

 whom Mr. Woodward's significant hint may be levelled) has taken 

 the Eschscholtzia by the hand, that I am not aware of. 



As I am at present writing on the subject of naturalization, I may 

 mention the fact that there is every probability of the Carduus Mari- 

 anus disappearing from the Monifieth station, near this place, where 

 it has only been naturalized, although I believe it is considered as 

 indigenous enough by some local botanists. I visited the place 

 about a fortnight ago, and found that it had totally disappeared from 

 the pasture-ground where it used to grow most abundantly, and is 

 now limited to two very stunted and unhealthy plants, which are con- 

 fined to the foot of the fence on the north side of the road, and oppo- 

 site from the old station. Its disappearance is no doubt mainly 

 caused by the turf becoming too firm to allow of its growth, it being 

 a plant that loves loose soil. 



I likewise visited the Perthshire station for the rare and interesting 

 Reseda lutea in June last, which is, I believe, allowed by botanists to 

 be an indigenous plant. It was kindly pointed out to me by my 

 friend Mr. David Gorrie, and I observed that the rocks where it 

 grows are beginning to be covered by vegetation of a more perma- 

 nent character, which will no doubt gradually displace the Reseda 

 until it is completely exterminated, unless some rural operations
