GENEBAL MORPHOLOGY OF THE PLANT 71 



when the terminal lobe is triangular, and the other lobes 

 which are also more or less of the same shape have their points 

 directed downwards towards the base of the lamina, as in the 

 Dandelion (fig- 127), the leaf is said to be runcinate ; when 

 a lyrate leaf has but one deep recess on each side, so that it 

 resembles a violin in shape, it is termed panduriform or fiddle- 

 shaped, as in the Eiddle Dock [fig. 128). 



Modiiioations of palmately veined leaves are also frequent. 

 When the blade of such a leaf is composed of five or more

branches whose wings are united about halfway from the base 

 to the tip, so that the whole has a resemblance to the palm of 

 the hand with spreading fingers, the leaf is termed palmate, 

 as in some species of Passion-flower (fig. 123). When the 

 union is less complete, as in the Castor-oil plant, the leaf is 

 described as palmatifid (fig. 124). There is little difference 

 hetween those two forms, and it is better to apply the term 

 ' palmate ' to compound leaves. These formslead on to the com- 

 pound leaf already described as digitate. Other intermediate
