Putting those together which have the three parts there 



shown blade, petiole, stip- 

 ules. (2) Those which have 

 only blade and petiole. (3) 

 Those consisting of blade 

 only. The first are said to 

 be stipulate and p etiolate, or 

 peiioled; the second are peti- 

 olate, and the third are sessile. Note 

 whether the stipules are leaf-like, or 

 thin and dry (scarious), or rudimentary. 

 Now rearrange your leaves in two 

 sets: (i) those broadest in the middle; 

 (2) those broadest near one end. Com- 

 pare the first, one at a time, with the 

 outlines in Fig. 41. Compare each of Fig - 40 - creeping wood violet. 



the second with the form shown in 

 Fig. 42. Then match each leaf, if 

 possible, with a form in Fig. 43 or in 

 Fig. 44, laying aside those which 

 you cannot match. Next, name the 

 forms of your "misfits," with the aid 

 of the following: 



A form midway between linear 

 and oblong is linear -oblong. If 

 nearer oblong it is narrowly oblong; 

 and if nearer linear it is broadly 

 So, too, we may have broadly oblong, or elliptic-
