Cinnabarina and a large variety of the Pentlandi. The first has an entirely separated 

 coronal stamina. The Pentlandi offers large differences but the ones cultivated under the 

 name of Echinopsis maximüiana have the stamen inserted in such a way that there is no 

 Space between the upper and lower row. 



One species that has great exterior resemblance with the Pentlandi and which is grown 

 under the name Echinocactus Cumingsii Salm, and whose flowers are lateraly placed as 

 they arise from areolas that are quite old. As I said before, this species is a group of 

 Pentlandi with small orange flowers and a short stem with graduated insertion of the 

 stamen, entirely common to the Echinocactus. 



Relative to the staminal insertion there is an unusual group that Lemaire has called 

 Cleistocactus. Under this name he grouped, more by appearance than by reason, two 

 dissimilar species in regards to the form of their bodies but very similar in regards the 

 configuration of their flowers. These are the Cereus colubrinus and its varieties and the 

 Echinopsis strodacantha. 



I will send you flowers of the Cereus colubrinus prepared in such a way so that the double 

 staminal insertion can be seen. I will also send you flowers of the Echinopsis rhodocantha 

 that are centrally grouped. They will be dried but not compressed. In this was you will be 

 able to judge the differences and similarities. 



The flower of the Cereus colubrinus of the variety Cereus Baumanni, is distinguished 

 from all other known Cereus by its flower whose principal characteristics are the 

 following: 



Small, tubulär, ascending flower. 

 Oblique, irregulär, bilobar limbs. 

 Very narrow neck surrounded by the staminal fascicles. 



Double staminal insertions with an inferior staminal insertion and a superior row inserted 

 in the neck. 



Stamen that project from the limb form the fascicles in the upper row. 



A spherical cavity (Lemaire) in the lower portion of the tubes, filled with a sugary liquid 

 that is inodorous, similar to the Pilocereus. 



This is the flower we are going to compare with the Echinopsis rhodocantha that I had the 

 opportunity to observe the 27th. of last June at Mr. Schlumberger's at Authieux close to 

 Rouen. This was a very unusual flower, never been completely described before ( at least, 

 to my knowledge); I thought that it would be prudent to make a transcript of the notes that
