Identify the mismatch from the following,

Options

A. Hypanthodium - Peduncle is fleshy deep cup like
B. Cyathium – Cup like involucre of bracts is found
C. Monochasial cyme Inflorescence with only one branch
D. Verticillaster - Inflorescence begins as a dichasial cyme but eventually turns into monochasial cymes around the node.

Answer

To identify the mismatch from the given options, we will analyze each term and its corresponding description carefully:

### Step 1: Analyze the first option - Hypanthodium
- **Description**: Hypanthodium is described as having a fleshy, cup-like peduncle.
- **Verification**: This structure is indeed found in Ficus (fig plants), where the peduncle forms a fleshy receptacle.
- **Conclusion**: This option is correct.

### Step 2: Analyze the second option - Scyanthium
- **Description**: Scyanthium is described as a cup-like structure formed by involucrae of bracts.
- **Verification**: This is accurate as Scyanthium is a type of inflorescence found in the Euphorbia family, where bracts form a cup-like arrangement for the flowers.
- **Conclusion**: This option is also correct.

### Step 3: Analyze the third option - Monocasial Chyme
- **Description**: Monocasial Chyme is described as having an inflorescence with only one branch.
- **Verification**: This description is misleading. Monocasial Chyme typically refers to a lateral branch originating from a terminal flower, which means it does not strictly have only one branch; it can have lateral branches.
- **Conclusion**: This option is incorrect and is the mismatch.

### Step 4: Analyze the fourth option - Verticillaster
- **Description**: Verticillaster is described as an inflorescence that starts as diacasial chyme and can turn into monocasial chyme.
- **Verification**: This description is accurate. Verticillaster is a type of inflorescence where flowers are arranged in whorls, and it can exhibit characteristics of both diacasial and monocasial arrangements.
- **Conclusion**: This option is correct.

### Final Conclusion:
The mismatch is the third option, Monocasial Chyme, as its description does not accurately reflect its characteristics.
