ribs or nerves, the smaller branches 
only then retaining the name of veins, 
or tlie latter are termed veinlets. The 
smaller \uiu8 are often coiinect<ad 
together, like the uieslies of a net ; they 
are then said to anastomose, and the 
leaf is said to bo reticulate or net- 
veined. When one princii«al vein niiis 
direct fronj the stalk towaids the vsuiii- 
mit of the leaf it is called the midrib. 
When several start from the stalk, 
diverge slightly without branching, and 
converge again towards the summit, 
they are said to be parallel, although 
not mathematically so. When 3 or 5 
or mote ribs or nerves diverge from the 
base, the loaf is 6ai<l to be 3-nerved, 
5-nerved, &o. ; but if the lateral ones 
diverge from the midrib a little above 
the base, the leaf is triplinerved, quin- 
tupliiierved, &c.
