not complete, of the Cactii that live on the high plateau of the Andes. In regards to the locations 

 that I have mentioned to you, wether in my letters or in my seed packages such as Andalgala, 

 Yacutula, las Capillitas, etc., (you will find them in good maps); these places are very 

 approachable and close to one another, all in the province of Catamarca, between 27 and 28 

 degrees latitud, south. 



One month ago, I received from this region a new shipment of seeds and flowers. I immediately 

 recognized some Cierges that are already growing here. These are perhaps the Cereus 

 Bonplandi that is very easy to recognize because of its very characteristic seeds and the Cereus 

 colubrinus (Cereus Baumanni) whose seeds and flowers can be identified without doubts. There 

 were also seeds from a large Cereus arborescents, that I would like to name Cereus 

 haematuricus, because its large fruits color the urine red. One day this Cereus frightened Dr. 

 Burmeister who had eaten those fruits and thought he had urinated blood. According to the seeds 

 and the flowers, I suppose this Cereus must belong to the group oi"Coerulescents"\ it is more 

 likely the Cereus coerulescens or perhaps the C chalybaeus. In this shipment there were also 

 seeds of a Rhipsalis and also a small Echinocactus of the Gymnocalycium group and another 

 globular Cactus whose seeds are without a doubt the Echinopsis. 



The species from which I sent you seeds have all germinated very well in my house; some young 

 plants are already as thick as nuts and are starting to show their characteristics. For example the 

 Echinopsis of Yacutula will most certainly become the Echinopsis campylacantha; but the 

 Pilocereus Pasacana and the Pilocereus Schickendantzi ( that are probably both the same 

 species) are quite new and will provide a southern comrade to your Cereus gigantus. 



This year I observed several new flowers of Cereus, among which are the C macrogonus, large 

 species similar to the peruvianus, but different because of its large fleshy flowers in which the 

 ovary and the tubes are decorated with a wooly skin or a very distinctive staminal crown. Then 

 the Cereus isogonus Hort, germ., whose plant is similar to your Cereus Emorgyi, has small red 

 flowers like the Cleistocactus that are similar to the Cereus Colubrinus ( Baumani). 

 If my letter finds you still in Empire City, please do me the favour of sending me an article on 

 the Opuntia Missouriens is, that is just about unknown in our collections, and also please send 

 me some small Echinocereus Simpsoni. 



On your return to St. Louis, please see if you have some seeds left over from your trip to 

 Arizona and in the spring please think of me when you find the Opuntia; it can easily be sent in 

 the mail. I promise you I will take good care of them and will spread them out in Europe. 



I always remain at your disposition and will send you from here all what gives you pleasure. 

 I wish you good health and I remain your devoted
