heads. Each smaller head (fig. 1.) consists of from 5 to 9 
florets, surrounded by ovate rather serrated leaflets, all of 
which, except the most exterior one, are white and mem- 
branous. The florets (fig. 2.) arise from the axil of each 
leaflet, and have a feathery pappus (fig. 4.) cup-shaped at its 
base, and then divided into 16 rays. The corolla (fig. 5.) has 
rather a funnel-shaped figure; the anthers have each two 
bristles at the base (fig. 3.); and the style, which is bulbous 
at the base is divided at the apex into two linear furrowed 
arms, each of which is terminated by a cushion-shaped 
dilatation.
