 the primary tuft ; in very luxuriant examples similar stolons are 

 thrown out from these secondary tufts. Petioles J inch to 2 inches 

 long, much longer than the lamina, which varies in breadth, being 

 sometimes scarcely broader than the petiole, at other times nearly 

 J inch across. Peduncles numerous, i to 1 inch long, slender, 

 without bracts, recurved in fruit. Calyx cup-shaped, 5-toothed.
