1182 CARDUACEAE 
2. Chrysopsis Tracyi Small. Foliage finely silvery silky. Stems wire-like, 3-5 dm. 
tall, sparingly branched above : leaves few, but the basal and lower cauline conspicuous on 
account of their extreme narrowness and great length ; blades mostly less than 1 mm. wide, 
1.5-3 dm. long, the upper cauline leaves much shorter, all terminating in a tuft of hairs: 
heads few, mostly 2 or 3: involucres 8-10 mm. high ; bracts lanceolate to almost linear, 
more or less cobwebby : ray-flowers rather numerous ; ligules yellow, 9-11 mm. long. 
Insand, Palma Sola, Florida. Winter.
