A new species of Potentilla (Rosaceae): P. baekdusanensis M. Kim

A new species, Potentilla baekdusanensis M. Kim, is described here. It is found in Baekdusan Mt., Korea. Potentilla baekdusanensis shares several characteristics (pinnately compound leaves, pubescent leaf blades and leaf petioles, different leaflets size, and absent stolons) with the related species P. fragarioides. However, this new species has small plants with short and curved hairs, 7 leaflets, small lower leaflets, a glabrous leaflet margin, and yellow petals with a reddish yellow base. In contrast, P. fragarioides are large plants with long and straight hairs, 9–15 leaflets, large lower leaflets, a ciliate leaf margin, and yellow petals without a reddish yellow base.
