and more naturally associated by older botanists with Hyoseris, a

1. Dwarf Arnoseris. Arnoseris pusilla, Gsertn. (Fig. 602.) 

 (Hyoseris, Eng. Bot. t. 95. Lapsana, Brit. Fl.) 



Leaves all radical, obovate or oblong, 

 toothed, and glabrous or nearly so. 

 Flower-stalks 4 to 8 inches high, slightly 

 branched, and leafless; the erect branches 

 or peduncles enlarged and hollow up-
