Name a taxon of family Liliaceae where leaf venation is reticulate :

Options

A. Allium
B. Asparagus
C. Smilax
D. Polygonatum

Explanation

**Step-by-Step Solution:**

1. **Understanding the Family Liliaceae**: The first step is to recognize that the family Liliaceae consists of plants that are primarily monocots. Monocots typically exhibit a specific type of leaf venation known as parallel venation.

2. **Identifying Leaf Venation Types**: In botany, leaf venation can be classified into two main types: parallel and reticulate. Parallel venation is characterized by veins that run parallel to each other, while reticulate venation forms a network of veins with a main vein branching into smaller veins and veinlets.

3. **Recognizing the Exception**: While most members of the Liliaceae family exhibit parallel venation, the question specifically asks for a taxon (genus) within this family that shows reticulate venation. This indicates that we are looking for an exception to the general rule.

4. **Naming the Taxon**: The genus that fits this criterion is **Smilax**. Smilax is a member of the Liliaceae family that exhibits reticulate venation despite being a monocot.

5. **Describing Smilax**: Smilax leaves are often heart-shaped and display a network of veins, which is characteristic of reticulate venation. This is an unusual trait for a member of the Liliaceae family, which typically exhibits parallel venation.

6. **Conclusion**: Therefore, the answer to the question is that the taxon of the family Liliaceae where leaf venation is reticulate is **Smilax**.
