In this type of venation, if only one principal vein is present, it is called unicostate,
and if several principal veins are present, it is called multicostate. 3. Reticulate
When the pattern of the veins in the lamina of the leaf is like a network, e.g. dicots
.
Parallel venation : A — Pinnate (unicostate) parallel; B — Palmate divergent; C
— Palmate (multicostate) convergent. OPPOSITE SUPERPOSED c TRIPINNATE

(II) Multicostate or palmate : When there are more than one midribs; it is sub-
divided into two types : (i) Convergent : When the midribs converge at the apex
e.g., Cinnamomum tamala, Zigyphus jujuba. (ii) Divergent : When the midribs
diverge ...
(b) Multicostate - reticulate venation : In this type many veins of equal strength
arise from the end of the petiole. Each vein further branches to give rise to
veinlets that form the network. The veins may be convergent (meeting at the apex
) or ...

Venation (arrangement of principal veins and veinlets in the lamina) Parallel (
veins parallel) unicostate (only one principal vein) Examples-canna, banana.
multicostate (many principal veins) convergent Examples -grasses, wheat,
bamboo.
