A dicot leaf is the leaf of a dicotyledonous plant (a plant whose seed has two cotyledons). In simple words, many common plants around us, like hibiscus, mango, and rose, have dicot leaves. The easiest way to recognise it is to look at the veins. If the veins form a net-like pattern, it is usually a dicot leaf.
Dicot Leaf with Examples
How to Identify a Dicot Leaf
- Reticulate venation: The veins form a net (a network) instead of running parallel.
- Midrib is prominent: A main central vein is clearly visible, with many side veins branching out.
- Leaf is often broad: Many dicot leaves are wider, but shape can still vary a lot.
Internal Structure (Useful for Biology Exams)
- Dorsiventral leaf: The upper and lower sides are not the same internally.
- Palisade mesophyll: Usually found towards the upper surface; it has more chloroplasts.
- Spongy mesophyll: Usually found towards the lower surface; it has more air spaces.
- Stomata: Often more on the lower surface in dicot leaves.

FAQs on Dicot Leaf
1: What is a dicot leaf?
A dicot leaf is the leaf of a dicotyledonous plant (a plant whose seed has two cotyledons). It usually shows reticulate (net-like) venation and a prominent midrib.
2: What is the easiest way to identify a dicot leaf?
Look at the veins. If the veins branch and form a net-like pattern (reticulate venation), it is usually a dicot leaf. Parallel veins are more common in monocot leaves.
3: Give 5 examples of dicot leaves.
Common examples include hibiscus, mango, guava, rose, and mustard.
4: What is dorsiventral in a dicot leaf?
Dorsiventral means that the upper and lower surfaces of the leaf differ internally. Typically, palisade mesophyll is towards the upper side, and spongy mesophyll is towards the lower side.
5: Are dicot leaves always broad?
Many dicot leaves are broad, but not all. The most reliable feature is reticulate venation, not the leaf size or shape.
