cause for altering a specific name, endless confusion would 

 arise in almost every old Genus wherein we have lately 

 become acquainted with many new species. I wish specific 

 names, when once given, were deemed mere arbitrary and 

 immutable terms. Trattinnick, it appears, has considered 

 L.urens, Jacq. and L. ambrosicefolia, Juss. as distinct, and 

 is followed by Sprengel; but as I am not acquainted with 

 the reasons for this opinion, as Jussieu is perfectly explicit 

 that they are the same, as his figure agrees sufficiently, and 

 as the differences noticed in his description appear to me to 

 be trifling, I must follow his opinion, supported as it is by 

 Persoon and Lamarck. 



The seeds of this most beautiful species were received at 

 the Botanic Garden, in spring last, from my invaluable 

 correspondent Mr. Cruckshanks, whose additions to our 

 stock of cultivated plants I take delight in recording. 

 They were gathered in the valley of Lima. The specimen 

 described was raised in a hot-bed, and flowered in the 

 greenhouse in the end of July. It has flowered in the 

 Royal Botanic Garden at Glasgow * ; and 1 understand 

 also in the neighbourhood of London. Graham.
