Jordan (" Amiales de la Soc. Linn, de 

 Lyon") has proposed several other species of 

 this section ; but as he gives no specific cha- 

 racters, it is difficult to tell on what he rests 

 in determining species. He arranges them in 

 three groups. The plants of the first are 

 strictly anmial, and their stems nearly solitary. 

 In the second, many stems arise from the 

 crown of the root. Flowers are usually pro- 

 duced in the first year, and the plant lives two 

 or three. In the tliird group they are strictly 

 perennial. The author promises further eluci- 

 dations.
