 at the broad base, sharply often doubly serrate, with straight glandular 

 teeth, and divided into 4 or 5 pairs of narrow acuminate lateral lobes; 

 deeply tinged with red and villose on both surfaces when they unfold, 

 nearly one-third grown when the flowers open about the 10th of May 

 and then very thin, light yellow-green and roughened above by short
