Dahlia. Cav. There is an arborescent 'species of this genus, which, in 

 Mexico, is said to grow as high as 40 ft. A plant of it was introduced into 

 the Liverpool Botanic Garden in 1835, and it was seen in the August of 

 that year by Dr. Neil! of Canonmills Cottage, who describes it as " a cutting, 

 resembling a middle-sized trunk or small stem of an elder bush, as thick as 

 a man's leg, and fully as woody as the elder. It was throwing out leaves 

 very like those of our herbaceous species." (^Gard. Mag., vol. xi. p. 680.) 

 On applying to Mr. Shepherd for information respecting this plant, he says 

 nothing of the plant alluded to by Dr. Neill, but informs us that he has " a 

 very fine plant, on a south wall, where it does better than in a green-house." 

 He also informs us that, in the Walton Nursery, there are a fine old plant, and 

 several young ones for sale; and that, in the green-house of C. Ta}lure, Esq., 

 there is a plant from 11 ft. to 14- ft. high. We also learn from Messrs. Lod- 

 diges, that they received the tree dahlia, a few years ago, from Mexico, but 

 afterwards lost it. Mr. M'Nab informs us that there are plants of it in the 

 Edinburgh Botanic Garden ; and Mr. Campbell, that there is one in the 

 Botanical and Horticultural Garden at Manchester.
