The Cereus pectin aboriginorum was no longer seen in Paris until it returned from Germany. I only 

 recognize some small samples that are not characteristic.

The Cereus Palmeri was saved by Mr. Martel who grew a Single one from your seeds. Today the plant 

 has multiplied, that is to say we have 4 or 5. 1 am keeping one for you. The plant is quite different from 

 the other known species; it has a certain resemblance to the Cereus pruinosus ( Syn. Cereus edulis 

 (Weber). 



I return to the Cereus pectin aboriginorum. You had sent me some large seeds that you considered the 

 largest of the Cereus species. But I can send you, if you wish, seeds of our old Cereus serpentinus, that 

 are even bigger ( 6 mm. long and 4 mm. thick). 



With great pleasure I accept your offer of sending me a an offshoot of the Agave sisalana, that I know 

 only through your description, unless it is identical with a plant that we grow here under the name of 

 Agave miradorensis ??? Could you send me a sample of the Agave virginica that is always very rare 

 here? The one that you sent me 5 years ago, stayed in Lyon at the Botanical Garden. 



Along with my other desires I include the Echinocereus longisetus, the Opuntia Rigelovii or Davisii and 

 lastly an authentic sample of the Opuntia missouriensis that I cannot obtain here. 



Three or four years ago you mentioned a large ramified Cereus, with thorny fruits from San Luis Potosi, 

 of which Mr Parry brought some drawings, the flowers and the fruits. I only know one large Cereus from 

 these regions that has fruits with many thorns: it is my Cereus queretarensis that we have grown here 

 and that has very characteristic thinly trabeculated seeds. Would you perhaps have a few seeds for me of 

 Parry' s Cereus seeds?. 



Among the two Opuntia of the Galapagos Islands, we were only able to preserve one Single Opuntia 

 myriacantha, that is at Mr. Martel' s. You would give me pleasure if you could send me another. 



I would like it if you could publish a paper in regards your Cacti. When you do this I will send you, if 

 you allow me, some notes from my observations on your species in the United States. At this time I am 

 still busy with the Argentinian Cactii. I have several correspondents in that country ( Catamara, Salta, 

 Jujury, etc.) and I receive from them seeds that seem very interesting with interesting notes. In a future 

 lettter I will teil about this at greater length. 



I salute you cordially and wish you good health, 



Your devoted Alb. Weber
