Read the following characters.
i. Diadelphous condition
ii. Vexillary aestivation
iii. Non - endospermic seed
The above characters belongs to family

Options

A. Solanaceae
B. Fabaceac
C. Cruciferae
D. Gramineae

Answer

To determine which plant family the given characters belong to, we will analyze each character step by step:

### Step 1: Analyze the Characters
1. **Diadelphous Condition**: This refers to a condition where the stamens are fused into two groups. This is a characteristic feature of certain plant families.

2. **Vexillary Aestivation**: This is a type of floral arrangement where the largest petal (the standard) overlaps the two smaller lateral petals, with the smallest petals forming the keel. This arrangement is also specific to certain families.

3. **Non-Endospermic Seed**: This indicates that the seeds do not contain endosperm; instead, the food reserves are stored in the cotyledons. This is a trait commonly found in dicotyledons.

### Step 2: Identify the Plant Families
Now, we will match these characteristics with the known families:

- **Solanaceae**:
- Stamens are typically not diadelphous (they are usually five and free).
- Aestivation is usually valvate.
- Seeds are endospermic.

- **Fabaceae**:
- Known for diadelphous stamens.
- Exhibits vexillary aestivation.
- Seeds are non-endospermic, with food stored in cotyledons.

- **Cruciferaceae**:
- Stamens can be diadelphous, but they typically exhibit imbricate aestivation.
- Seeds can be non-endospermic, but the floral arrangement does not match vexillary.

- **Gramineae (Poaceae)**:
- This family is monocotyledonous, which typically has endospermic seeds.
- Does not exhibit diadelphous stamens or vexillary aestivation.

### Step 3: Conclusion
Based on the analysis, the characters provided (diadelphous condition, vexillary aestivation, and non-endospermic seeds) are characteristic of the **Fabaceae** family.

### Final Answer
The above characters belong to the **Fabaceae** family.
