Wollastonia (plant)
Wollastonia is a genus of flowering plants in the family Asteraceae, often referred to as the sunflower family. These plants are typically found in tropical and subtropical regions of Asia, the Pacific Islands, and Australia.
Description:
Wollastonia species are typically herbaceous perennials or shrubs, often characterized by their spreading or climbing habit. They often feature opposite leaves, which can vary in shape and texture depending on the specific species. The flowers are usually yellow and daisy-like, arranged in flowerheads known as capitula. These flowerheads may occur singly or in clusters.
Taxonomy and Classification:
The taxonomy of Wollastonia has been subject to revisions. Previously, some species now classified under Wollastonia were included in other genera, such as Wedelia. Modern phylogenetic studies have helped to clarify the relationships between these closely related groups.
Habitat and Distribution:
Wollastonia species are often found in coastal areas, along forest edges, and in disturbed habitats. Their ability to tolerate a range of conditions has allowed them to establish in various environments within their native ranges.
Ecology and Uses:
Some species of Wollastonia are known to be used in traditional medicine in certain regions. They may also play a role in coastal dune stabilization or as ground cover plants. The plants often attract pollinators, contributing to the biodiversity of their ecosystems.
Conservation Status:
The conservation status of individual Wollastonia species varies. Some species may be relatively common and widespread, while others may be rare or threatened due to habitat loss or other factors. Further research is often needed to fully assess the conservation needs of specific species within this genus.
