XCm. AMARANTACE2E, AMARANTH FAMILY. 



Weeds and some ornamental plants, chiefly herbs, essentially 

 like the next family, but the flowers provided with dry and 

 mostly scarious crowded persistent bracts, and the fruit some- 

 times several-seeded. The filaments are often united into a 

 tube or cup. The cultivated sorts are ornamental, like Im- 

 mortelles, on account of their colored dry bracts which do not 

 wither.
