Biology : PU-CET (U.G) 2016 Panjab University Entrance Exam With Answers

Monocotyledonous leaf showing reticulate venation is not a common characteristic found in monocots. Generally, monocots have parallel venation in their leaves. However, there are a few exceptions to this rule, and one such exception is the genus Smilax. Smilax is a monocotyledonous plant that has reticulate venation in its leaves. Reticulate venation is a characteristic feature of dicotyledonous plants, but it is rare in monocots.

Therefore, the correct answer is A) Smilax.
