These floral characters are of a specific family . Identify the plant which shows the following characters.
1 . Flower-bisexual , zygomorphic
2. Corolla - vexillary aestivation
3. Androecium - diadelphous
4. Gynoecium - ovary superior
5. Seed-Non-endospermic

Options

A. Petunia
B. Colchicum
C. Indigofera
D. Belladona

Answer

To identify the plant based on the given floral characters, we will analyze each character step by step:

1. **Flower - Bisexual, Zygomorphic**:
- A bisexual flower has both male (stamens) and female (pistils) reproductive organs. Zygomorphic flowers are symmetrical along one plane.
- This character suggests that we are looking for a plant in the Fabaceae family, as many members of this family exhibit these traits.

**Hint**: Look for plants with flowers that have both reproductive organs and are symmetrical in one plane.

2. **Corolla - Vexillary Aestivation**:
- Vexillary aestivation refers to a specific arrangement of petals where one petal (the standard) is larger and overlaps the two lateral petals, which in turn overlap the two smaller petals (the wings).
- This is a characteristic feature of the Fabaceae family.

**Hint**: Identify plants with a distinct arrangement of petals where one petal is dominant over the others.

3. **Androecium - Diadelphous**:
- Diadelphous means that the stamens are united in two groups, typically nine fused together and one free.
- This is another defining trait of the Fabaceae family.

**Hint**: Look for plants where the stamens are grouped into two distinct bundles.

4. **Gynoecium - Ovary Superior**:
- A superior ovary means that the ovary is positioned above the point of attachment of the other floral parts.
- This is consistent with the characteristics of many Fabaceae plants.

**Hint**: Check if the ovary is positioned above the other floral structures.

5. **Seed - Non-endospermic**:
- Non-endospermic seeds are those where the endosperm is consumed during seed development, meaning the seed contains mostly cotyledons.
- This is typical of many legumes in the Fabaceae family.

**Hint**: Determine if the seeds lack endosperm and primarily consist of cotyledons.

After analyzing all the floral characters, we can conclude that the plant exhibiting all these characteristics belongs to the **Fabaceae family**, specifically the genus **Indigofera**. Therefore, the answer is **Option C: Indigofera**.
