Two neio American Roses. 125 



Art. XI. Dimensions of large Trees and Shrubs, collected with a 

 view to a Supplement to the Arboretum Britannicum. 



It is our intention, in the course of the present year, to publish a Supiilement 

 to the Arboretum Britannicum, chiefly for the sake of introducing descriptions 

 and figures of the new species of pines and firs introduced from Mexico by 

 the Horticultural Society, and of certain trees and shrubs recently raised from 

 Himalayan seeds (all given in our abridged Arboretum) ; but partly, also, to 

 record the dimensions of remarkable specimens of trees and shrubs now 

 growing in Britain, which have been sent us since the Arboretum was com- 

 posed, or which may be sent in the course of the next three months. 



We shall therefore be greatly obliged to our readers and correspondents, if 

 they will cooperate with us in this matter, and send us dimensions of large 

 specimens with as little delay as possible.

EoV.4 vubifolia elegans, the Prairie Rose. — A fine climbing rose of very robust 

 habit, often making shoots of from 10 ft. to 12 ft. in the season. Flowers 

 semi-double, in clusters of from eighteen to twenty-five in each, and of a deep 

 pink colour. Found by R. Buist of Philadelphia, in the state of Ohio.

R()s« xubifblia var. Prairie Queen. — A seedling of i?6sa nibif olia elegans, 

 which was raised by Mr. S. Feast of Baltimore. Of a stronger habit than R. 

 r. elegans ; flowers quite double, and imbricated, in clusters. Similar, but 

 siqjerior, to the strong-growing varieties of Noisettes. Colour bright pink. R. 

 Buist. 



Mr. J. W. Brown, who brought over a plant of each of the above roses 

 from Mr. Buist, saw both in flower in Mr. Buist's nursery in the summer 

 of 1842, and bears testimony to the truth of the above descriptions by Mr. 

 Buist. — London, Dec. 1842.
