EXERCISE IX. 
Farts of Compound Leaves . 
Leaves, in growing, are sometimes changed from 
simple to slightly lobed, from slightly to deeply lobed, 
and from lobed to compound. When feather-veined 
leaves, wdth their stout middle rib, are thus changed, 
they become pinnately lobed, or pinnately compound 
as in Fig. 68. 
Leaves with several ribs, palmate-veined leaves, 
Fig. 68. 
become palmately lobed or palmately compound, as 
shown in Fig. 69. They are usually called digitate 
leaves, from the resemblance of the leaflets to fingers. 
Leaflet.— One of the blades of a compound leaf. 
Pet'iolule.— The stem of a leaflet. 
StFpels.— The stipules of leaflets. 
Ra'chis. — The continuation of the petiole to 
which leaflets are attached. 
Gather a great many compound leaves and look 
for their different parts.
