﻿AGAVE MACROACANTHJ 



J AGAVES. 24; 



The two admitted species of the Macroacanthac may 

 separated as follows : 



Several other names, which have been practically book 

 names for the last forty years, should be touched on in con- 

 nection with the foregoing, since they pertained originally to 

 plants which Karwinski had sent to the Munich Garden, 

 perhaps from the vicinity of Oaxaca. 



In the enumeration of species that he was cultivating in 

 1834, Salm* includes A. lam, A. punctata and A. ruhescms, 

 and describes (p. 306) the two last named, giving as a syno- 

 nym of rubescens, A. flaccida, under which name he had 

 received the plant from Munich. Another name, serrulatn, 

 of Karwinski, appears in Otto's bare enumeration of Berlin 

 Agaves, in 1842. 



A. laxa, as it had been labeled at Munich, is listed by 

 Steudel in 1841, Otto in 1842, Roemer in 1847, and Kunthin 

 1850 (with inclusion — p. 837 — of an ambiguous location of 

 it under A. Karwinskii by Otto,t and a suggestion — p. 838 

 —by Bouche, who had seen the Berlin specimen, that it might 

 be the same as pugioniformis). It was first described in 

 Salm'sf monograph of 1859, where it stands between Kar- 

 vnnskii and pugioniformis. The following year Koch§ 

 located it between A. Jacquiniana, which he seems to have 

 understood, and Karwimkyi. In his commentary on Koch's 

 revision, Salm II groups laxa,serrulata and rubescens as a Unear, 

 lax, serrulate foliaged series of a division "Micracanthae," 

 apart from his " Macracanthae " in which the macroacanlha 

 series are placed. The same considerations led JacobiH in

under Karwinskii, might really be rather laxa.
