forebearer the Agave Ghiesbrechtii; but others are more or less laeviorus. Lastly one of the 

 samples that comes authentically from the same seed, has completely smooth seeds (Agave 

 Kerchovi incremis).One can rub the the edges of the leaves from top to bottom and from bottom 

 to top and not feel the most minimal roughness. ! ! ! ! ! Here are 2 seeds from the same capsule that 

 would have been for Jacobi, not only distinct species but even different sections!

 synonymies; being a recent catalogue it has included many of the most common species. 

 Therefore, for example, in the Echinocactus I put together all the Stenogoni of the crispatus 

 group. The confusion that reigns in the books and in the gardens among all the species described 

 pertaining this group, refers simply to the fact that there is no Single species that in itself varies 

 enormously. It is the same thing in regards to the Malacocarpus, that are evidently more or less 

 constant forms of a similar type. 



I indicated the numerous Synonyms of the Echinocactus ingens, etc. etc. 



In regards this catalogue I want to teil you which is the present State of synonymy of the Cereus 

 mexicanus of which in the past I sent you these descriptions: 



Cereus edulissimus or edulis is positively
