Aquatic Plant

一枝香

Scientific name:

Vernonia cinerea (L.) Less. 

Chinese common name:

一枝香、傷寒草、枝香草

Family: 

Asteraceae 

Morphology

Root:

They feature a main taproot that penetrates deeply into the soil to seek water and nutrients, well-developed lateral roots that help stabilize the plant and absorb more nutrients, high adaptability that allows them to grow in various soil types, including poor soils, and rapid growth, which helps the plant establish and expand its growth area quickly.

Stem:

Herbaceous, with slender stems that branch in the upper part, the entire plant is covered with short grayish-white hairs.

Leaf:

Leaves are alternate, petiolate, obovate or spatulate, with blunt or short-pointed tips and shallowly serrated edges, and are hairy on both surfaces.

Flower:

The capitulum is arranged in a loose corymb, consisting entirely of tubular, bisexual flowers that are pale purplish-red. The flowers are slender and tubular, about twice the length of the involucre. The blooming period is year-round.

Fruit and Seed: 

The achene is cylindrical, brown, and hairy, with numerous white pappus bristles.

Aquatic Adaptations

It has several characteristics that enable it to adapt to aquatic environments: 1. It has high water tolerance, allowing it to grow in moist environments without being affected by excess water. 

2. Its extensive root system anchors it securely in water or wetlands, absorbing sufficient nutrients and oxygen. The plant's rapid growth helps it cover wetland or water-edge areas quickly, preventing soil erosion. 

3. Its strong reproductive ability through seeds and stem segments, especially in moist environments, facilitates easy spread and establishment.

4. Its leaves are adapted to high humidity, reducing water evaporation while maintaining good photosynthetic capability.

Distribution

Native distribution:

It is distributed throughout tropical Asia.

Current distribution:

The current distribution covers Asia, Africa, the Americas, and some other tropical and subtropical regions.

Ecology

Habitat:

It typically thrives in warm and humid environments, including riverbanks, lakeshores, pondsides, marshlands, field edges, and roadsides. It prefers locations with ample sunlight but can also tolerate semi-shaded conditions.

Pollination:

Pollination of it is typically carried out by insects, especially bees and other pollen-carrying insects. The flowers produce nectar and pollen, attracting insects to collect them, thereby facilitating the transfer of pollen between flowers and completing the pollination process.

Dispersal:

It typically spreads through seeds and underground stems. Its seeds can be dispersed by wind or water to other areas, while underground stems can extend in the soil, producing new plants. Additionally, Chinese violet can also spread through human intervention, such as people planting it in new areas for use as a yard or garden plant.

Applications and Interesting things

Applications:

In traditional herbal medicine, it has been utilized for its medicinal properties. Its leaves and stems contain certain chemical compounds believed to have medicinal value. It is used to treat various symptoms and ailments such as inflammation, pain relief, and fever reduction. Additionally, it is commonly employed in gardening and landscape design as ground cover, enhancing the beauty of gardens, parks, and roadside areas.

Interesting things:

Some traditional herbal medicines use it to treat various symptoms and ailments such as inflammation, pain relief, and fever reduction. However, it is important to note that while it is used in traditional herbal medicine, further scientific research and validation are needed to determine its medicinal value and safety.
