The flowers are usually fragrant, particularly at night, and are pollinated by moths. The fruit is a berry that is often fleshy and contains numerous small seeds.

Distribution and Habitat:

Hillia species are found in a variety of habitats, including rainforests, cloud forests, and dry forests. They often grow as epiphytes, lithophytes, or terrestrial plants.

Taxonomy:

The genus Hillia was named after Sir John Hill, an English botanist. The number of species within the genus is debated and subject to ongoing taxonomic revision, but is generally considered to contain between 20 and 40 species.

Uses:

Some Hillia species have been used traditionally in herbal medicine. The fruits may be edible, though caution is advised as some species may contain toxic compounds. The plants are also sometimes cultivated as ornamentals due to their attractive flowers and foliage.

Conservation:

The conservation status of many Hillia species is not well known. Habitat loss and degradation pose threats to some species, particularly those with restricted distributions.
