 Scales of the involucre various, appendiculate or ex- 

 appendiculate, muticous or spinous. A large and poly- 

 morphous genus, abundant in Europe, and well known 

 under the name of Corn-flower. Though occasionally 

 met with in com fields, scarcely an Indian genus. 



Sub-tribe. Carthame^. Capitula manyflowered. ho- 

 wogamousy or rarely the exterior forets sUnle. Involucre
