I would like to point out to you that your Agave falcata from Saltillo, that I remember having 

 seen very frequently in the north of Mexico, appears to belong to the species of Agave striata 

 Zucc. In our gardens we find it under the name of Bonapartia rigidifolia. The Agave stricta, 

 recurva and Hystrix seem to be simple varieties of this type. 



Your Agave angustissima, could it not be the filifera variety of the Agave geminifloral That 

 variety if very common here and it is called Bonapartia filamentosa. or Bjunua filamentosa or 

 filifera. It has nothing similar to the Agave filifera or Schidigera or filamentosa that has very 

 large leaves. Something that is important for you to remember, is that Hartweg found the Agave 

 geminiflora in the surroundings of Tepic ( Journal of the Horticultural Society of London Vol I 

 pag. 180 (1846). He found this abundantly in Tepic in a village called Ocotillo with shafts 

 measuring 12 to 18 feet. 



Your Yucca seeds and most of the Agave ones, were given in the last few days to Mr. Martel. 

 The Cacti and the rest of the Agaves will be sown in one month at a time when the heat will be 

 more constant. 



Would you have seeds of the Echinocereus phoenicus and gonacanthusl I do not recall any 

 authentic plant. 



Could you send me a copy of your work on the Yucca? Would also be possible to obtain a copy 

 of your Wisligenus Report For a long time I was unable to find it in the French and German 

 libraries. 



Please excuse the length of this letter which I sent with good will. 

 I remain respectfully, 



Alb. Weber
