﻿AGAVE MACROACANTHA AND ALLIED EUAGAVES. 235 



concave leaves of A. pugioniformis when young that Jacobi 

 transferred it from its earlier association next the other 

 large-toothed species, macroacantha and Karwinskii (where 

 it had still been left by Salm in his list of 1861), to his 

 own group of "Canaliculatae," in which (p. 18) its colloca- 

 tion is particularly unfortunate in several respects: but his 

 description (p. 142), though specimens are not cited, is 

 evidently drawn from living material, presumably in Salm's 

 collection. 



Cels, of Paris, a dealer in succulents who seems to have 

 given unusually intelligent study to his collections, pubUshed 

 an "Agavearum systema naturaUs" in the form of a chart 

 folded into his trade catalogue of 1865, in which he places 

 macroacantha (with Bessereriana Roezl as a synonym) under 

 his own "Angustifohae," treating "A. jmgimiferus [pug- 

 ioniformis] Zucc." as a variety pi^ixmiferus of it; but he makes 

 no mention of Karwinskii. 



Karwinski's plants of all these Agaves were probably col- 

 lected in the state of Oaxaca, and perhaps not far from the city 

 of that name. Roezl and Besserer more certainly collected 

 theirs in the vicinity of Tehuacan, between Oaxaca and 

 Puebla. . , „ 



At about this time various dealers were hstmg A. Besserer- 

 iana, Bessereriami Candida, and hremfolin. and longifolixi forms 

 of the latter; and Laurentius* advertised— with seemingly 

 characteristic and certainly well executed figures of them— 

 two forms which he caUed A. Besserermna longifolm glauca 

 and A. Bessereriana longifolia viridis,-\ stating, however, 

 that neither had any connection with the earher Bessereriami. 

 These plants seem to represent the fruits of Besserer sown 

 collecting in 1868. , , ^ 



Jacobi secured these and other Agaves offered by Lauren- 

 tius, and publishedj no less than four supposedly new species
