one can finally always find them. I therefore encourage you to look for them carefully in your specimen 

 of flssuratum. I have no doubt that if you look for them you will find the seeds.My friend Martel will put 

 all his care and all his talent to make them grow, if you could send me some of them. He was succesful 

 in growing some pretty plants from the Anhalonium sulcatum, prismaticwn, areolosum (Lern), and also a 

 new species to which I gave the name of A nhalonium trigonum. 



The voyage of Mr. Parry and Mr. Palmer to Mexico promises to be very rewarding in regards to many of 

 their new discoveries. Could you write them and give them some instructions? I perhaps could have 

 given them some advice but it is without doubt too late. I wonder if you would be so kind, and ask them 

 to research the several species of Lechuguilla and all the plants that furnish the Amalia or vegetable 

 soap.They are common in the north of Mexico. Also teil them about the Agave Considerati or Victoriae 

 close to Monterrey, on the road that goes to Saltillo.The Anhalonium are found around Saltillo, mainly 

 close to Buenavista {Anhalonium prismaticum). A few kilometers north of Monterrey, between Marin 

 and Ramos; one can find many on the calcareous hüls ( on the edges of the road and at the entrance of 

 the village of Maria, in front of the church), a distinct species of Anhalonium that is called Atrigonum. 

 I was told that in the north of the State of Zacatecas there are several specimens.The Mexicans call them 

 Siempre Vivos del Monte, or also Peyote. The last name is usually given to the Anhalonium Williamsii. 

 Our travelers will need to look for it mainly on the road from Parras to Chihuahua. 



Today I have no more time to write to you, but another day I will send you more details. Thank you for 

 the seeds that will be sown in the near future.
