off from the midrib and branch again into veinlets that run to- 
gether and form a network, or mesh. (FIG. 30.) Netted- 
veined leaves are said to be Feather—Veined when the sec- 
ondary veins all start from the sides of the midrib, running 
from the base to the apex of the leaf. (Fic. 31.) They are 
called Palmately—Veined when several veins of equal size 
start from the same point at the base of the leaf and spread out 
towards the margin. 
Parallel-Veined leaves are those in which the main veins run 
side by side, without branching or running together. (Fic. 32.) 
The veining of the leaves is always in complete harmony 
with their shape, so that much can be learned by noticing this 
feature carefully. 
FIG. 33- 

Leaves vary greatly in general outline, and the following 
terms are used to designate some of their common forms: 
Linear: the narrowest form of a leaf—several times longer 
than broad : grass-like. (Fic. 32.) 
Lanceolate : long and narrow, slightly broader at the base 
and tapering towards the apex. (FIG. 30.) 
Oblanceolate isa reversed lanceolate. 
Oblong: when two or three times broader than long. 
(Fic. 31.) 
Elliptical ; oblong but tapering at both ends. (Fic. 33.) . 
Oval: broadly elliptical. (Fic. 34.) 
Ovate: when the outline is similar to the shape of an egg, 
the broader end downward.
