The leaf venation is reticulate in species of Smilax, a member of family Liliaceae.

Answer

To determine whether the statement "The leaf venation is reticulate in species of Smilax, a member of family Liliaceae" is true or false, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Leaf Venation**:
- Leaf venation refers to the arrangement of veins and veinlets in the leaf lamina. It plays a crucial role in providing structural support and facilitating the transport of nutrients and water.

2. **Identify Types of Venation**:
- There are two main types of venation:
- **Reticulate Venation**: This is characterized by a network of veinlets forming a reticulum. It is commonly found in dicots.
- **Parallel Venation**: In this type, veins run parallel to each other, which is typical of monocots.

3. **Examine Smilax**:
- Smilax is a genus that is typically classified under the family Smilacaceae. However, some botanists also associate it with the family Liliaceae.

4. **Check the Venation of Smilax**:
- Despite being a monocot, Smilax exhibits reticulate venation, which is an exception to the general rule that monocots have parallel venation.

5. **Evaluate the Statement**:
- The statement claims that Smilax has reticulate venation and belongs to the family Liliaceae. Since Smilax does indeed have reticulate venation and can be associated with Liliaceae by some botanists, we can conclude that the statement is true.

### Conclusion:
The statement "The leaf venation is reticulate in species of Smilax, a member of family Liliaceae" is **true**.
