This is a perennial herb which grows up to a meter tall, or possibly more. The caudex has a ring of fleshy roots. The leaves have highly dissected blades borne on long, stout petioles. The inflorescence is an umbel of many tiny white flowers. The plant has a scent similar to parsley.[1]
This plant, the only Peucedanum found in the Hawaiian Islands, grows in coastal canyons and on cliffs overlooking the ocean. There are two small populations in the Waianae Range of Oahu, three on Molokai, ten on Kauai, and one on Keopuka Rock, an islet close to the coast of Maui.[2]
There are fewer than 10,000 individuals, and perhaps fewer than 5,000.[1]
Threats to the species include non-native plants such as lantana (Lantana camara), as well as feral goats, hiking and the maintenance of hiking trails, fires, landslides and rockslides.[2]
