A garden sport of the preceding with a median yellow or white band 

 bordered with green, and likewise tinged with red when young. 



Neither of these variegated forms comes true to seed, and 

 the intensity of the variegation, particularly the red, is apt 

 to change with age and season. Knowledge of the garden

 question may be wrongly placed, and what is called f . 

 Menandi below may perhaps be identical with one of them.
