TRADESCANTIA 



last is hardy in the open ground in central New York. 

 All of them are used for baskets and vases. The two

 as Wandering Jew. All of them may have striped 

 foliage. See Commelina and Zehrina.

TEAGOPOGON (Greek for goat's beard). Comp6sitm. 

 Goat's Beard. Between 30 and 40 species of erect bi- 

 ennial or perennial herbs with narrow grass-like leaves 

 and heads of yellow or purple flowers, belonging to the 

 ligulate section of the composite family (tribe Cichori- 

 acew). Florets perfect, with slender style-branches and 

 sagittate anthers; pappus composed of bristles in a 

 single series and mostly raised on a beak; involucre 

 cylindric or nearly so, with approximately equal bracts 

 in a single row. The Tragopogons are mostly weedy 

 plants with a tap-root. They are native to outhem 

 Europe, northern Africa and central and southern 

 Asia. One of them is cultivated for its edible tap-root 

 (salsify) and another is now a frequent weed in this 

 country. The flowers of these open only in the mom-
