Lowellia
Lowellia is a genus of flowering plants in the family Rubiaceae, native to tropical and subtropical regions of the Americas. The genus is named after Nathaniel P. Lowell, an American botanist who collected and described many species in the region. Lowellia species are typically shrubs or small trees, with simple, alternate leaves and small, fragrant flowers that are often white or pinkish. The flowers are usually tubular and arranged in clusters at the ends of branches. The fruit is a capsule that contains several seeds. Lowellia species are valued for their ornamental qualities and are often cultivated in gardens for their attractive flowers and foliage. Some species are also used in traditional medicine for their various medicinal properties. The genus includes approximately 20 recognized species, with the most well-known being Lowellia acuminata, which is widely cultivated for its attractive flowers and is often referred to as the "Lowellia tree."
