 cor3mbs. The whole outer surface of the style is thickly covered with small capitate 

 sweeping-hairs. These are short-stalked, and their heads are glandular. The inner 

 surfaces of both stylar branches are closely beset with minute stigmatic papillae. 

 Kerner states that some species possess no sweeping-hairs. Flower class SL.
