A STUDY OF LEAVES. 



PARALLEL-VEINED LEAVES. 



Parallel-veined leaves are also of two sorts, 

 Feather-veined and Palmate-veined. 



In Feather-veined the veins extend from the 

 mid-vein, without branching, to the margin. 



In Palmate-veined the veins all extend from 

 the petiole without branching. 



Parallel Feather-veined. 



Parallel Palmate-veined. 



The flowers of plants having net-veined leaves 

 are generally in fours or fives ; that is, they have 

 four or five sepals, the same number of petals, etc. 



The flowers of plants having parallel-veined 

 leaves are generally in threes, or some number of 

 times three — as six, nine, twelve, etc. It is very rare 

 to find a three-parted flower with net-veined leaves.
