XLVI. A new Account of the Genus Echeveria. By A. H. 

 Haworth, Esq. F.L.S, fyc. fyc. 



To the Editors of the Philosophical Magazine and Annals. 

 Gentlemen, 

 TT AVING just examined and described a fine new succulent 

 ■*■"■" plant at Mr. Tate's Nursery in Sloane-street, which he 

 has recently raised from Mexican seeds, and which is now 

 blooming for the first time in Europe, amongst many other 

 equally rare and well-managed plants ; I send you hereunder 

 a full account of it, and four other species of the same genus; 

 to which I have added all their synonyms. 



This new plant, belonging to DeCandolle's new genus 

 Echeveria, I have called, from its ample leaves, Echeveria 

 grandifolia. 



In my ninth decade of new succulent plants, published in 

 your Journal in 1826, I announced to you (inter alia) that 

 Cotyledon coccinea of Cavanilles, and Cotyledon umbilicus of 

 Linne, would each form the type of a new genus, but for 

 want of proper specimens regretted my inability at that time 

 to give you sufficient characters. This, however, is now the 

 less to be lamented, as DeCandolle has done it for us, in the 

 third volume of his Prodromus, just published ; and to the 

 above-mentioned Cotyledon coccinea has added my Cotyledon 

 ccespitosa, (which is a native of California, although we used 

 to think it African,) and two new species from Mexico. 



If you can find room for this communication in the next 

 Number of your Journal, you will much oblige 



Your old correspondent and friend, 

 Chelsea, Aug. 10, 1828. A. H. Haworth.
