Mr. Haworth's FiJ'tli Decade of ncuo Succulent Plants. 279 



The tirao salt is used in the country as a kind of mordant 

 loan extract of tobacco, which, when held in the mouth, pro- 

 duces a secretion of saliva : this preparation is called chimo or 

 moo. At Merida they mix four anobas of urao with eight of 

 tobacco ; at Varinas the urao forms but one-fourth of the pro- 

 j>ortion of tobacco. The moo contains less urao than the 

 chimo.

To the Editor of the Philosophical Magazine and Journal. 



Sir, 



A FIFTH Decade of new Succulent Plants I have here- 



^^^- under the pleasure of adding to those you have already 



been pleased to publish in your useful and scientific Magazine. 



Some of these new jilants are very remarkable ones, and 

 they are all of the Aloean family ; all recently received from 

 that inexhaustible mine of succulent plants the Cape of Good 

 Hope ; and were all detected there in truly native wilds, by 

 that successful explorer of those arid regions Mr. Bowie; 

 who safely transmitted them to our gracious sovereign's un- 

 rivaled gardens at Kew, where they are now flourishing, and 

 scarcely seem to miss their warm and native skies. 



Three of these plants with remote alternate sheathing leaves 

 are said to have red, or yellowneat flowers; and one of these, 

 which bloomed at Kew, is reported to have had porrected 

 stamens ; which character, combined with the remote and al- 

 ternate habit of the leaves, may perhaps lead to the future 

 construction of a new genus : — nevertheless, I consider the 

 leaves of all Aloean plants as actually alternate, although fi-om 

 their usually compacted aggregation seldom offering ocular 

 demonstration of their being so. Those of many arborescent 

 and other Scmpcrvivu, and likewise of the Mcscmbrijanthema 

 capitata, I know to be alternate; and they are quite as densely 

 crowded, and after the same manner, prior to the production 

 of flowers ; as very gradually appears by their method of 

 evolving their bractcate inflorescence.
