half their length : leaves mostly radical, forming a compact rosu- 

 late cluster on the crown of the short tap-root, outer ones large, 

 blade 3 cm. long on petioles 3-6 cm., diminishing in size and 

 length of petiole towards the center, oval to oblong, entire or 

 tooth-angled, some of the smaller sub-hastate, cauline only one 

 or two, oblong, 2-3 cm., petioled : pods oval to elliptic, sub-acute 

 or more usually obtuse, 5-6 mm. long, slender style as long or 

 longer : pedicels ascending, curved, about 1 cm. long. 



Perhaps most closely allied to L. montana Wats, by its fruit, 



but separated from it by its conspicuous rosette of basal leaves, its 



fewer stems, its few, long-petioled cauline leaves, its smaller pod 



and its later development, 

 this soecies in late Aup*us1
