Mr. Haworth's New Account of the Genus Kalanchoe. 301 



The two instances I have given of ascertaining the forms 

 of arbitrary functions, may suffice to convey an idea of the 

 general principles on which a like inquiry is to be conducted 

 in any other question that is proposed. The nature of the 

 question itself must determine the precise manner of the 

 process.

XLVII. ' A New Accoutit of the Genus Kalanchoe. By 

 A. H. Haworth, Esq. F.L.S. Sfc. 



To the Editors of the Philosophical Magazine a?id Annals. 

 Gentlemen, 

 TTEREUNDER I send you an improved botanical account 

 ■*•-■• of the genus Kalanchoe of Adanson, to which I have 

 added one new species from the Royal Gardens of Kew. It 

 is a very beautiful plant, with deep yellow flowers, and was 

 sent thither last year from the East Indies by my friend 

 Dr. Wallich, who is now actually engaged in a very mag- 

 nificent work on Indian plants, in which will be figured all 

 the more useful and conspicuous species of that interesting 

 country; and towards which the public at large, and more 

 especially the botanists of Europe, look forward with the 

 liighest and most eager expectations. 



The descriptions of this genus and its proper species hereto- 

 fore published by myself or others, I have re-modelled, and 

 formed the whole into new sections, to which I have added all 

 their synonyma (as far as practicable to me), so as to give a 

 monographical sketch of the genus. Hoping the result will 

 prove acceptable to your botanical readers, 



I remain, Gentlemen, your old Correspondent, 



Chelsea, Aug. 5, 1829. A. H. Ha worth.
