 and connected by a thick fiber. A new corm is produced annually, in advance 

 of the old, which dries up the second or third year. Leaf elliptic or ovate, 3 to 5 

 long, many-veined, twice longer than the petiole, arising late in the season from 

 the new corm, remaining through the winter, until the scape (12 to 18' high)
