Century Dictionary and Cyclopedia
- n tragopogon A genus of composite plants, of the tribe Cichoriaceæ and subtribe Scorzonereæ. It is characterized by entire leaves and flower-heads with uniseriate acuminate involucral bracts, the achenes tapering into a long and slender or a very short beak, with plumose pappus. Over 50 species have been described, but not all are now accepted. They are natives of Europe, northern Africa, and temperate and subtropical Asia. They are biennial or perennial herbs, often covered in places with floccose wool. They bear linear alternate clasping leaves which are commonly grass-like, and terminal yellow or bluish flower-heads on long peduncles. For T. porrifolius see salsify, and for T. pratensis see goat's-beard, buck's-beard, and noon-flower. Both species are locally naturalized in the United States.
