Write Down the Scientific Name of China Rose Plant. Give its Floral Formula

The scientific name of the China Rose plant is Hibiscus rosa-sinensis. This plant, commonly known for its vibrant flowers, is a member of the Malvaceae family. The China Rose is widely cultivated for ornamental purposes, and its bright blooms are admired for their beauty and medicinal properties. Now, let’s dive deeper into the floral formula of the China Rose and explore its structure.

Floral Formula of China Rose (Hibiscus rosa-sinensis)

The floral formula provides a shorthand representation of the flower’s structural details, including its parts like sepals, petals, stamens, and pistils. For the China Rose, the floral formula is as follows:

K(5) C(5) A(5) G(1)

Here’s a breakdown of what each symbol represents:

• K(5): The calyx is made up of 5 sepals, which are green and protect the bud before it blooms.
• C(5): The corolla has 5 petals, typically large, colorful, and arranged in a funnel-like shape.
• A(5): The androecium, or male reproductive part, consists of 5 stamens, all fused together to form a central column.
• G(1): The gynoecium, or female reproductive part, consists of a single carpel, which holds the ovary.

Flower Structure and Pollination

China Rose flowers are large and showy, with a prominent central column formed by the fused stamens. The flower typically has five petals arranged symmetrically, which attract pollinators like bees, butterflies, and birds. The China Rose is an ideal example of a complete flower since it has all four essential floral parts: calyx, corolla, androecium, and gynoecium.

Medicinal Uses and Importance

Apart from its ornamental value, Hibiscus rosa-sinensis has various medicinal uses. Its flowers, leaves, and roots are often used in traditional medicine to treat conditions like coughs, hair loss, and high blood pressure. The plant is also rich in antioxidants and other beneficial compounds, making it a valuable resource in herbal treatments.

The scientific name of China Rose plant is Hibiscus rosa-sinensis, and its floral formula is K(5) C(5) A(5) G(1). Understanding the structure and floral formula of this plant helps biology students grasp fundamental concepts of plant reproduction and flower anatomy. Additionally, it’s a great example of how flowers evolve to attract pollinators and serve ecological purposes.
