I. Chicorace.e. Chicory Group 

 i. Tragopogon {Goat's-beard) 



i. T. pratensis (Yellow Goat's-beard). Involucre about as long 

 as, or longer than the corolla ; leaves broad at the base, very long, 

 tapering, channelled, undivided ; flower-stalks slightly thickened 

 above. An erect glaucous plant about 2 feet high, with long grass- 

 like leaves and large bright yellow flowers, which always close early 

 in the day, and have hence gained for the plant the name of John- 

 go-to-bed-at-noon. The pappus is very beautiful, the feathery 

 down being raised on a long stalk, and interlaced so as to form a 

 kind of shallow cup. Meadows; not uncommon. Fl. June, July. 

 Biennial. 



2. T. porrifolius (Salsafy). Though not a British species, is occa- 

 sionally found in moist meadows. In 

 ^\^ habit it resembles the last, but has 



purple flowers. It was formerly much 

 cultivated for the sake of its fleshy tap 

 roots, which were boiled or stewed and 

 eaten. Though still advertised in seeds- 

 men's catalogues, its place is now largely 

 supplied by Scorzonera Hispanica.
