Pogonanthus

Pogonanthus is a genus of flowering plants in the family Apocynaceae. These plants are native to the Himalayas, particularly Nepal and India. They are known for their attractive, star-shaped flowers and their ability to thrive in challenging mountainous environments. The genus was first described in 1846 by Joseph Dalton Hooker.

Species within the Pogonanthus genus are typically small, herbaceous perennials. They often grow in rocky areas or on steep slopes, demonstrating resilience to harsh conditions such as cold temperatures and limited soil. The flowers are generally bright yellow or orange, with five petals that spread outwards. They bloom during the summer months and are often pollinated by insects. The leaves are usually simple, lance-shaped, and arranged alternately along the stem.

The taxonomy of Pogonanthus has seen some debate, with some classifications placing it within the Asclepiadoideae subfamily of Apocynaceae. The genus is relatively small, with only a few recognized species. While not widely cultivated, Pogonanthus species are of interest to botanists and horticulturists for their unique adaptations and ornamental potential. Their conservation status varies by species, with some facing threats due to habitat loss and overcollection.
