DBACOCEPHALUM (from drakon, a dragon, and 

 kephale, a head ; in reference to the ringent corollas). 

 Dragon's Head. OBD. Labiata. A genus of about 

 thirty species of perennial or annual herbs, natives of

 usually Miaceous; corolla generally large, with a very 

 wide throat and a bilabiate limb. Leaves entire, denta 

 or palmatifid. Very showy border plants when in flower. 

 All are hardy, and delight in a cool situation. The porei 

 nial species are readily increased by divisions rf"jj| 

 or by cuttings of the young shoots, in April or May 

 annuals, by seeds, sown in the open, in April. Perennials, 

 except where otherwise stated.
