1558. Membranes of corolla purplish. 



Subtilely beset with glandule-bearing short hairlets ; leaves

 usually from cordate- to lanceolar-ovate, all denticulated ; 

 flowers large, axillary, solitary, on rather short stalks ; 

 corolla nearly glabrous outside, with a lateral narrow 

 protrusion towards the base ; fruit almost ellipsoid ; seeds 

 flat, pale-brownish, without any marginal expansion.

Dwarf ; leaves nearly glabrous, the radical leaves crowded, 

 from elliptic- to linear-lanceolar, entire, the floral leaves 

 much reduced in size ; panicle beset with very short

mostly entire. 



Never tall, nearly glabrous ; radical leaves crowded ; stem-

 small, usually many in each panicle ; all corolla-lobes on 

 both sides equally membranous-expanded ; fruit quite
