J. americana pkta. Terracciano, Primo Contributo ad una Monografia 

 delle Agave. 41. (1885). — This includes all of the variegated forms of americana 

 and also A. ontata and A. picta. 



Except for well-drawn but very peculiar figures 

 published in Marnock'sFloricultural Magazinein 1840 

 as representing a nearly white-margined form of this 

 species, it might be said that all references to varie- 

 gated Agaves before 185Q could be safely ranged 

 undQT umericana, — as has usually been done, Though 

 the leaf illustration in the plate referred to shows 

 americana passably well except for the very minute 

 terminal spine, the flowers and buds are rather those 

 of one of the soholifera series, though not exactly 

 those of any that I have seen, and the habit sketch 

 might represent a plant of the same series rather 

 than americana. The foregoing references can 

 hardly be placed under either of

Variegation marginal, froni yellowish white ranging to deep golden yellow. 



Though there is ambiguity concerning the localization of the 

 variegation in the earliest references, the fact that J oly der c in 1779, 

 Merrem in 181 1 and Haworth in 1812 knew only marginal variega- 

 tions makes it improbable that either the striate or median-banded form 

 had earlier attracted attention, but both, in several modifications,
