subsequently substituted that of cat/ioides (Hamburg Gar- 
tenflor., xxii. 214), with the sanction of Lemaire, under whose 
authority it stands, stating at the same time as his reason 
for this, that it differs from his fowrcroydes. The true four- 
croydes of Jacobi is described by himself (Hamburg Garten- 
flor., xxi. 167) ; and to it is referred as a synonym Z. iatly, C. 
Koch, not 4. ivtly of Haworth; and in Jacobi’s general enu- 
meration of Agaves (Regel Gartenflor., xvii. 8348) 4. ixtlioides 
and fourcroydes stand next one another in one section, whilst 
A. ivtly is placed in another; but judging from the descrip- 
tions all three may well belong to one species. 
Dxscr. Stem very short; constricted above the root.
