THE FIRST BOOK OF BOTANY. 



The words acute, acuminate, and obtuse may be 

 used to describe bases as well as apices, and, when we 

 wish to say that a shape is less acute or less acumi- 

 nate than Figs. 36 and 37, we may say it is sub-acute 

 or sub-acuminate, as in the schedule to Fig. 45.
