and then quickly ceasing, the leaf incurving into a long narrow 
entire acumination. Such leaves are 2% x r4 in., with slender 
petioles 1 in. or less long, 12 such or less, about 1% in. apart. 
Upper cauline leaves are the most characteristic, and give the 
plant its subentire aspect; 8 such or fewer, 3 x I in. or less,

though none remains at maturity below. Pedicels widely forking,

minute straight linear bractlet which sometimes becomes obovate.
