 the form of the flowers to the Cereus colubrinus and a variety of the Echinocereus. 

 Uriacanthus. I am sending you two samples of flowers prepared in this way and call your 

 attention to these plants. I desire your opinion. 



The first of these flowers is the Echinocereus horripilus Lemaire. In regards to 

 this curious species that has been cultivated in France for more than 30 years and that I 

 found in Mexico close to Saltillo, we found ourselves in the face of the same question we 

 had in the Mammilaria ovimamma. This Echinocereus horripilus that has been included 

 until now in the section of the Theloideus, carries its flowers at the top of its 

 mammiliform tubercles just like the Echinocactus. The flower comes out of the aureola 

 immediately below the spines. The aureole stays by itself
