papothem

Papothem is a genus of flowering plants in the family Asteraceae, native to the eastern United States. The name "Papothem" is derived from the Greek words "papa" meaning "father" and "thema" meaning "place," referring to the plant's native habitat. The genus contains about 10 species, all of which are perennial herbs or subshrubs.

Papothem plants are characterized by their alternate, pinnately compound leaves, which are typically 3-5 lobed. The flowers are small, yellow, and arranged in dense, flat-topped clusters called capitula. Each capitulum contains numerous disc florets, but no ray florets, which is a distinctive feature of the genus.

The most well-known species is Papothem glabrum, commonly known as the smooth papothem. This species is native to the Appalachian Mountains and is often used in landscaping and wildflower gardens due to its attractive flowers and hardy nature. Other species in the genus include Papothem tomentosum, which has a woolly texture, and Papothem pubescens, which has pubescent leaves.

Papothem plants are typically found in moist, shaded habitats such as stream banks, woodlands, and forests. They are pollinated by insects, particularly bees, and play a role in supporting local ecosystems by providing food and habitat for various species. The genus is not currently considered to be at risk, but like many wildflowers, it may be threatened by habitat loss and fragmentation.
