9. APLEC'TRUM, Nutt. ADAM AND EVE. PUTTY-ROOT. (Gr. a,

 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 tho scape (12 to 18' high)
