ply pinnate, having several leaflets 
arranged along both sides of the com- 
mon stalk. This common stalk, an- 
swering to the midvein of a simple 
leat, is called the rachis. 
37. Among pinnate leaves, there 
are, at least, three important distine- 
tions. Observe the Figs. 59, 60, and 
61. One of them ends with an odd 
leaflet, and is called odd-pinnate. 
Another ends with a pair of leaflets, 
and is equally pinnate. Another still 
has its alternate leaflets smaller, and is interruptedly pinnate.
