The flower here represented was produced in a stove in 

 the Garden of the Horticultural Society in May last ; but I 

 have no doubt that a greenhouse would suit the species 

 equally well. 



Nothins: is more difficult than to understand the defini- 

 tions of the species of Canna in Botanical books, owing to 

 the vagueness with which the parts of the corolla are spoken 

 of. It should always be borne in mind that a flower of this 

 genus consists of four series of organs, each of which ought 

 to be defined separately, and which are explained by the 

 diagram No. 4. in the accompanying plate. The first row 

 represents the calyx, the second the outer limb of the corolla, 

 the third the inner limb of the corolla, and the fourth the 

 stamens, of which two only are present, both petaloid, and 

 one only bearing the anther. If these circumstances were 

 attended to, in describing Cannas, the species would be 

 distinguished upon much more intelligible diff'erences than 

 they now are. 



Fig. 1. is the apex of the style; 2. a transverse section 

 of the ovary ; 3. the apex of the petaloid filament, with the 

 anther upon one edge.
