 sea MexicAna, Hort.) is a handsome form introduced 

 from Texas by John Lewis Childs in 1892. It was found 

 in the wild. "We first secured the pink," Mr. Childs 

 writes, "and afterwards someone else sent us the white, 

 blush and the other shades, all from Texas." In some 

 respects it differs markedly from CE. tetraptera, and It 

 is not impossible that it is a distinct species. In culti- 

 vation it is a trailing plant. The Ivs. tend to be broader 

 and less pointed than in CE. tetraptera. It does not pro- 

 duce seed in the North, but is readily propagated by 

 cuttings. It is an excellent plant either for the flower 

 garden or for pots in the conservatory. It is popularly 

 known as the "Mexican Evening Primrose."
