For the drawing, technical character, and following ac- 

 count of this plant, we are indebted to our highly valued 

 correspondent the Hon. and Rev. William Herbert. 



This very ornamental bulb was raised four years ago from 

 a seed of Ismene Amancaes, which had been fertilized by 

 the pollen of Ismene Calathina. It is interesting as con- 

 firming the generic character of Ismene, from which no 

 intermixture with the cognate genus Hymenocallis has been 

 produced, though many attempts have been made; and also 

 by the great change which has been wrought in it by the 

 impression of the male species. The colour of the flower is 

 intermediate, and the scent, though very powerful, is not 

 delightfully fragrant as in Calathina, nor so disagreeable 

 as that of Amancaes. The constitution is vigorous, like that 

 of the former species, from which it inherits also a more 



* A classical name applied to this genus by Mr. Herbert. Ismene was a 

 daughter of CEdipus.
