D. verticillaster

Answer

**Step-by-Step Solution:**

1. **Understanding Inflorescence**: Inflorescence refers to the arrangement of flowers on a plant. It can be classified into two main types: cymose and racemose.

2. **Cymose Inflorescence**: In cymose inflorescence, the flowers are arranged in a definite pattern, and the main axis terminates in a flower. This means that the growth of the main axis stops when a flower develops at its tip.

3. **Racemose Inflorescence**: In contrast, racemose inflorescence has an indefinite arrangement of flowers. The main axis does not terminate in a flower, allowing for continuous growth. This type of inflorescence features an unbranched axis.

4. **Characteristics of Racemose**: In racemose inflorescence, flowers develop along the elongated unbranched axis, with each flower typically having a short stalk called a pedicel.

5. **Identifying the Correct Answer**: Based on the definitions and characteristics discussed, the inflorescence with an unbranched axis is called racemose. Therefore, the correct answer to the question is "racemose."

**Final Answer**: The inflorescence with an unbranched axis is called racemose.
