﻿246 MISSOURI BOTANICAL GARDEN. 



name by Kunth in 1850, except that he reports Bouche, who 

 had grown it in the Berhn Garden, as considering it similar to 

 laxa. It was first described in Salm's monograph of 1859, 

 and placed between pugioniformis and rubescens. Koch, 

 who adds nothing to the knowledge of it, locates it between 

 flavescens and ruhescens. Jacobi* redescribed Salm's original 

 specimen in 1865, when he transferred serrulata, ruhescens 

 and jmgioniformis to his own flaccid-leaved group. With 

 the passing of the plants seen by Otto, Salm and Jacobi, 

 A. serrulata has become merely a book consideration; and, 

 though Van Houttet hsted an Agave under this name in 1868, 

 I have found no evidence that it has been recognized since. 

 What was cultivated in gardens about 1877 under this name 

 has been said to be the very different A. densiflora.X Salm's 

 location of serrulata between pugioniformis and rubescens, 

 with Jacobi's arrangement § of these apart from macroa- 

 cantha or Karmnskii, is followed by Baker || (who had never 

 seen it), Ricasoli, Hemsley and Segura. Terracciano,1[ 

 apparently on a plant of the sobolifera series found under this 

 name, but the history of which is not given, describes, with 

 flower and fruit details, a broad, green-leaved paniculate 

 Agave as A. sobolifera serrulata, giving serrulata as a synonym, 

 and suggesting, with question, the propriety of uniting it with 

 his own A. sobolifera laxa, which is made the equivalent of 

 the laxa of Baker rather than Salm, though the latter is cited. 



The history of the Karwinski plants cannot be closed with- 

 out reference to the name A. Zuccarinii, once applied in the 

 Berlin Garden to a plant evidently received from Munich 

 and possibly representing one of the numerous foregoing 

 species or synonyms. This was included in Otto's list of 

 1842 and Kunth's enumeration of 1850 where it passes into
