The specific characters and descriptions of Cavanilles seldom do him any credit, and respecting 
this Dahlia he has blundered as usual ; for its leaflets ‘are neither more acuminated than those o 
the others, nor smooth on their lower disk ; and the ligulated florets of the second variety are of a 
deep marygold colour, not scarlet ; so that Ido not wonder at Dr. Sims hesitating to quote him. 
itis a more delicate species than the other: the stem frequently tinged with purple, quite 
round, and covered with a fine glaucous dew: principal leaves bipinnated often with one or two 
very small leaflets at the base of the partial petioles: Flowers a little fragrant, but when they 
decay exhaling a stronger smell, more like that of Saffron. The variety with yellow flowers has 
only been lately introduced into this country from Madrid, by the Right Honb* Lady Holland, 
and flowered for the first time this Autumn.
