The correct Answer is:
**Step-by-Step Solution:** 1. **Identify the Flower:** The China rose is also known as hibiscus. 2. **Determine the Morphological Characteristics:** - **Ectinomorphic:** The flowers can be divided into three or more identical sectors, indicating symmetry. They can be sectioned and show relation to each other by rotation around the center. - **Hypogynous:** In this type, the ovary is superior, meaning it is positioned above the other floral parts. - **Twisted Estivation:** The arrangement of sepals and petals is such that they overlap each other. Each sepal or petal overlaps its neighbor in a manner where one margin is outside and the other is inside. 3. **Differentiate from Other Types:** - **Zygomorphic:** Flowers that can be divided into two equal halves. - **Epigynous:** Flowers where the ovary is inferior, meaning the other parts are above the ovary. - **Imbricate Estivation:** Overlapping pattern of petals and sepals. - **Valvet Estivation:** Petals and sepals are placed end to end without overlapping. 4. **Conclusion:** Based on the characteristics discussed, the flowers of the China rose (hibiscus) are ectinomorphic, hypogynous, and exhibit twisted estivation. **Final Answer:** In China rose, the flowers are ectinomorphic, hypogynous, and show twisted estivation. ---
