margin. A plant reported to be naturalized in Burma seems 

 to be this, or at least very near to it. Nothing is known of the 

 qualities of either form (if they are distinct), nor can they be 

 properly identified, but they are allied possibly to Agave 

 Keratto of Miller. 



The Saharanpur specimens are named "Agave Ixtli," which 

 is certainly inapplicable. The original A. Ixtli of Karwinshi 

 came from Yucatan, and his description (which is quoted in 

 Kunth's Enum., V. p. 835) leads us to think that his plant 

 must be near the very marked species which has been described 

 by Mr. Baker in the Kew Bulletin (Nos. 67, 68, July-August 

 1892, CCLVII, False Sisal of Florida). There has been 

 great confusion as to A. Ixtli, as will be perceived on refer- 

 ence to Bot. Mag. 5893, where an Agave Ixtly of Hawotth is 

 mentioned as distinct from that of Koch* besides Jacobi's, 

 which was possibly intended to be the A, Ixtli of Karwinaki. 



In the notice just quoted it is suggested that A. ixtly 

 Jacobi may belong to the same species with that writer's A . 

 fourcroydes and A. ixtlioides, of which 5893 Bot. Mag. is a 

 representation. 



In the Index Kewensis the " ixtly " () of Koch (ii) of 

 Haworth, and (Hi) of Jacobi are not separately mentioned, 

 while A. ixtli of Karwinshi is reduced, with "fourcroydes" 

 " ixtlioides" and A. sisalana, Pem'ne to the A. rigida of 

 Miller. 



These identifications rest on the conclusions of Enge/mann 

 (Notes on Agave reprinted in Bot. Works, Cambridge, Mass. p. 

 312, 188 7). His account is too long for quotation as a whole, 

 but an extract will be given under the next species. He identi- 

 fies an Agave that flowered at Antibes in 1872 with A. Ixtli 

 (presumably of Karwinshi), and this again with a wild Agave 

 of Yucatan, called by the Indians Chelem. Of the ' Chelem ' he 

 says * which I refer with little doubt to Miller's old A. riyida? 



He gives no grounds for this last identification, while his 

 description has not much in common with Karwinshi 's of 

 A. Ixtli, and differs in material respects from that of Miller's 

 A. rigida : other difficulties apart, an insuperable bar presents

 Rev. Sill. 189 Karwinski's A. Ixtli only would appear to have been includ- 

 ed and is doubtless that intended.
