 corolla, 2 of them shorter than the other pair ; ovary superior, 

 2-celled, 2-seeded ; style one ; flowers axillary, and leaves 

 opposite. 



Grow in the temperate parts of both continents ; not a very

Rhinanthus. L. 13. 2. 



From the Greek for nose and flower, as its compressed corolla

B. coccinea. L. Painted Cup, about a foot high, with alter- 

 nate leaves, and a cluster of flowers at the summit, which have 

 bright-scarlet floral leaves or bracts, generally 3-cleft, which give

From the Greek, for black and wheat, because its seed, which 

 resembles wheat, gives a black color to bread. Only a few spe-
