S.52 SYXGENESIA— POLYGAMIA-.^QU. Apargiu. 



Willdenow, as explained in Kees's Cydopcvdia, has no founda- 

 tion in truth. 

 The exotic ^. crispa, which likewise has hairy forets, is most akin 

 to this species ; but the long tapering rough beak of its seeds 

 affords a clear distinction. This beak is different from the proper 

 stalk of a seed-down. 



2. A. hh'fa. Deficient Hawkbit. 



Stalks naked, single-flowerecl. Leaves toothed, rough. Ca- 

 lyx nearly smooth. Outer row of seeds crowned with 

 scales only.

Perennial. July, Augu.st. 



Smaller than the last. Root abrupt, not tapering. Leaves often 

 but slightly toothed, and not runcinate. Pubescence often sim- 

 ple, but on the whole not materially different from that of 

 J. hispida. Fl. but half the size of that species, red underneath. 

 Cat. almost entirely smooth. Florets destitute of iiairs on the 

 tube, as well as of glands under their tips; the inner ones with 

 a less perfect corolla than the outer row. The 5ee</is of the latter 

 are crowned with a row of short, flat, toothed scales only, while 

 those of the former bear sessile feathery down. These charac- 

 ters abundantly distinguish this long-doubtful species from the 

 last, and the exotic A. crispa is known from both of them by the 

 long beaks of its seeds, all bearing feathery down. 



3. A Tarnxuci. Dandelion Hawkbit. 



Stalks mosdy single-fiowered ; tumid and haiiy at the sum- 

 mit. Leaves smooth, runcinate. Calyx shaggy.
