Thymus possesses two types of plants, female flowered and hermaphrodite flowered. The condition is called
(a) Trioecious
(b) Polygamous
(c) Gynomonoecious
(d) Gynodioecious

Options

A. Trioecious
B. Polygamous
C. Gynomonoecious
D. Gynodioecious.

Answer

To solve the question regarding the classification of Thymus plants based on their flower types, we can follow these steps:

### Step 1: Understand the Types of Flowers
Thymus has two types of plants:
- Female flowered plants (pistillate)
- Hermaphrodite flowered plants (having both male and female reproductive structures)

### Step 2: Analyze the Options
Now, let's analyze the options provided:
- (a) **Trioecious**: This term refers to plants that have three types of flowers: male (staminate), female (pistillate), and hermaphrodite. Since Thymus only has two types, this option is incorrect.

- (b) **Polygamous**: This term describes plants that have both male, female, and bisexual flowers. This does not fit the description of Thymus, which has only female and hermaphrodite flowers. Thus, this option is also incorrect.

- (c) **Gynomonoecious**: This term refers to plants that have both female (pistillate) and hermaphrodite flowers, which matches the condition of Thymus. This option is likely correct.

- (d) **Gynodioecious**: This term indicates a condition where there are only female (pistillate) and hermaphrodite plants, but it does not fit the description of having both types of flowers on the same plant. Therefore, this option is incorrect.

### Step 3: Conclusion
Given the analysis, the correct answer is:
**(c) Gynomonoecious**.
