PART II 



KEYS TO THE GENERA 

 DIRECTIONS FOR USE OF THE KEYS 



General Cautions. — In using any of the keys: (1) 

 Never read any hut tJie state77ients to which you are directed 

 hy the letter in parenthesis; (2) read all the statements fol- 

 lowing the given letter to ivhich you are directed and choose 

 the one ivhich seems nearest right about your specimen. 



General Directions. — All the keys have several starred 

 (*) sections. These are all to be read and one chosen. 

 At the end of this there is a letter in parenthesis and 

 just below it a statement following tins same letter. 

 Following or further down the page, but at the same dis- 

 tance from the left side of the page, other statements 

 coming after the same letter are to be found. All these 

 need to be read. The one that best suits the plant in 

 hand is always to be chosen and the letter in parenthesis 

 noted. Proceed till a name, instead of a letter in paren- 

 thesis, occurs. 



In this Part II there is given the name of the genus of 

 the plant, with the page in Part III where the different 

 species of the genus are described and illustrated. If there 

 are several genera given, turn to all the pages noted and, 

 by the descriptions or the figures, conclude which is the 

 right one. In Part III the keys are to be used as in Part 

 II, but the names there given are the full names of the 

 plants. 



In the General Opening Key on page 34 the numbered
