no. It has parallel veins.
corn leaves have parallel veins
No
Corn leaves typically have parallel venation, meaning that the veins run parallel to each other along the length of the leaf. Dicot leaves, on the other hand, have a branching network of veins that spread out from a central midrib. Additionally, corn leaves are generally longer and narrower compared to the broader shape of dicot leaves.

No
It has netted leaves
In parallel venation, the veins are all smaller in size and parallel or nearly parallel to one another, although a series of smaller veins connects the large veins. Parallel venation occurs in the leaves of nearly all monocotyledonous Angiosperms, whose embryos have one cotyledon, as in flowering plants such as lillies and grasses
No
rambutan leaves is parallel or netted veins
Coconut leaves have parallel veins. This means the veins run alongside each other in a uniform direction from the base to the tip of the leaf, without forming a net-like pattern.
Corn has leaves with parallel venation as it is monocotyledonous
