MISSOURI BOTANICAL GARDEN. 



18G5 to place these three species in his own group "Canal- 

 iculatae," to which pugioniformis, Rumphii and yuccaefolia 

 were added. His description of lam seems to have been 

 drawn from a re-examination of Salm's plant of 1859. Cels, 

 m his "Systema" tabulation of 1865, places A. CantuLa 

 and A. lam at the end of his "Angustifoliae," treating 

 "Rhumphii;' serrulata and nibescens as varieties of the latter, 

 with punctata and flaccida as synonyms of ruhescens. Baker* 

 held Uxa for a possible variety of A. vivipara, which, as he 

 understood it, was practically A. Cantala (of which Rumphii 

 has been considered to be a synonym). He clearly had not 

 seen the species of Salm and Jacobi, and his laxa is apparently 

 justly considered by Drummond and Prain in their recent 

 notes on Agave and Furcraea in Indiaf to be only a flaccid 

 form of A. Cantala. Terracciano,J following Kunth's ex- 

 pression as to Otto's queried identification of lam with 

 Kwrwinskvi, places it (p. 44) as a possible synonym of A. 

 Ixlh, to which the latter is referred. He elsewhere (p. 47) 

 treats lam (of Baker) as a variety of A. sobolifera, to which 

 rather than vivipara (in Baker's sense, i. e. Cantala) he considers 

 it related. 



A. punctata, listed (p. 8) and described (p. 306) by Salm§ 

 m 1834, had been so named in the Berlin Garden, presumably 

 on a plant received from Munich, though there seems now to 

 be no way of learning what name it bore there. In 1842 Otto 

 considered it to be the same as Kanvinskii, or perhaps equiv- 

 alent to Zaxa,— both Munich names. In this he was followed 

 by Kunth in 1850, and Terracciano in 1885, the latter placing 

 it, as such, under A. Ixtli. In his monograph of 1859, || 

 Salm, who must be considered to have known it better 

 than any one else, entere it as a frank synonym of 

 rubescens, m which treatment he is followed by Koch and 

 Jacobi,— the name practically disappearing after the latter,
