Question

What is the type of leaf outline in these figures?

The two main kinds of venation are: parallel venation when the apparent veins (visible to, the
unaided eye) run parallel to each other not dividing and subdividing to form meshes; and netted
venation or reticulate venation when the apparent veins branch and rebranch into finer and finer
veinlets which unite with each other to form apparent meshes. Parallel-veined leaves are simple

parallel when the veins run from the base or near the base to the apex or near the apex; and pinnate
parallel, or pinniparallel when the veins run from the midrib to the margins. Netted-veined leaves are
pinnate net or pinnately Hetted when major veins runs from the side of the midrib to the margins and
palmate net or palmately Ketted or digitately nerved or, in peltate leaves, Fadiately nerved when
several equally strong veins radiate from the top of the petiole.
Palmately netted leaves, with the veins all starting from the base are called 3-nerved, 5-
nerved, etc., according to the number of major nerves, but when some of the major veins start just
above the base they are called 3-plinerved, 5-plinerved, etc. When the nerves are obscured and not
evident to the naked eye, they are referre to as obsolete or wanting.
