Telosma

Telosma is a genus of flowering plants in the family Apocynaceae (dogbane family). It is native to tropical and subtropical Asia and Australia. These are generally perennial climbers or shrubs, known for their fragrant flowers, particularly at night.

Description

Telosma species are characterized by their twining or climbing habit. They possess simple, opposite leaves. The flowers are typically small, tubular or salverform (trumpet-shaped), and come in shades of yellow, greenish-yellow, or white. The corolla lobes are often twisted or overlapping. The fruit is a follicle, containing numerous seeds. A notable feature of many species is the strong, sweet fragrance of the flowers, which attracts pollinators like moths.

Species

Several species are recognized within the genus Telosma. One of the most well-known is Telosma cordata (formerly Telosma minor), commonly known as the Chinese violet, Tonkin creeper, or cowslip creeper. This species is widely cultivated for its fragrant flowers, which are used in culinary applications and traditional medicine in some regions. Other species exist, though their taxonomic status and distribution can sometimes be subject to revision.

Cultivation and Uses

Telosma cordata is frequently grown as an ornamental plant in gardens and landscapes, particularly in tropical and subtropical climates. Its fragrant flowers make it a desirable addition to outdoor spaces. The flowers are also edible and used in Southeast Asian cuisine, often added to soups, stir-fries, or curries. In traditional medicine, the plant is believed to possess various medicinal properties.

Synonymy and Taxonomy

The taxonomic history of Telosma has involved some revisions and reclassifications. Some species previously classified under other genera may have been moved into Telosma, and vice versa. Telosma cordata, for example, was formerly known as Telosma minor. Current taxonomic classifications should be consulted for the most up-to-date information on species included within the genus.
