 Banks of rivulets on the Upper Guadaloupe ; also on the San 

 Fernando and the Liano. August. — Cultivated from Texan 

 seeds, this most showy and almost gigantic species flowers in 

 October, either as an annual or a biennial, bearing profusion 

 of flowers, of which an unusual number are open at the same 

 time. Although altogether like that of an ordinary annual or 

 biennial, the tall stem becomes perfectly woody below, and 

 often two inches in diameter at the base. The expanded 

 corolla is four or five inches in diameter, as large as in (E. 

 Missouriensis ; the anthers three fourths of an inch, and the 

 stigmas half an inch, in length. 1
