 equahng the scapes, rather stout, blade large, 8-14 cm. long (in- 

 cluding the lobes), curved on the margins, subacute, lobes short, 

 rounded-obtuse, about one third the length of the rest of the 

 blade: bracts linear-lanceolate, 15-20 mm. long, subscarious, 

 greenish-veined, spreading or reflexed : flowers large, about 2 cm.
