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 Rin 10: Cuetotio 1alu daw 7 20 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.
