Weber, Alb. 



Undated no location mentioned 



Cereus Scheeri S. 



Echinocereus Engelmanni ( False name)! 

 Stern 20 cms in length and 3 cms thick. 

 Soft at the base 

 Hard, yellowish, green. 

 There are 8-9 sides per crest. 



On the adult stems the sides are subspiral and grow on the length of the stems in a 

 semicircle. There are some deep grooves and some that are nearly flat at the base. 

 The areolas are close, at a distance of 1/2 cm. and small and sunk in, that is to say the 

 crest is above the areola. This is tuberculated. 



Short, rigid but weak thorns, arranged in rings of 8-9, the short ones having a maximum 

 length of 1 cm. The inner ones are no longer that 1 1/2 cm. 



The flowers come out of a tear of the epidermis beneath the areolas, just like all the 

 Echinocereus that I observed (which I verified today on the Echinocereus Blankii, 

 stramonius, acifer, multicostatus, pancispinus, polyacanthus) 



They live several days, opening in the daytime and closing when the sun drops into the 

 horizon. 



The flowers of the Echinocereus Engelmanni et Salm open in the evening and close the 

 next morning, this it does for several days in a row (5 or 6 according to Mr Guedency). 

 The flowers last several days and fade when the suns sets. 



The variety Dyck has a nuance which is much more vivid than the Engelmanni, one could 

 say it is nearly rose color. 



Echinocereus ochroleucotrichos is synonymous with the Stramonius mayor. 

 Cereus multicostaticus flower similar to the acifer with a thicker stem.
