and that the naked flowers were seated in a line upon the 

 inner surface of the spatha itself, and on that part of it 

 which appeared to correspond with 3 nerves which are more 

 conspicuous on the back of the spatha than are the rest. 

 Again, I found the filaments of the stamens distinctly jointed 

 upon a tubercle, from which they readily fall off; and these, 

 as well as the sterile stamens (or peltate fleshy glands) occupy 

 the central portion of the line of flowers, the pistils being ar- 

 ranged along the outside of the line. From these, and other 

 characters, I am induced to form a distinct genus of this plant; 

 — Spathicarpa ; a name intended to convey its most striking 

 peculiarity; the spatha bearing the fructification. The term 

 Spathantha is already applied to another genus, or I should 

 have preferred it. 



I have figured and described the Caladium Seguinum {Exot. 

 Fl. t. I.) as having the lower part of the spadix united to the 

 spatha, which may be considered an approach to the structure 

 of the present genus.
