Abstract

Impatiens piufanensis var. villosa, a new variety of Balsaminaceae from Hubei and Hunan, China, is described and illustrated here. Morphologically, it can be distinguished from the nominate variety by its stem, leaves, lateral sepals, lower sepal and the midvein of upper petal covered by dense white villus and puberulent peduncles and pedicels. The phylogenetic analysis based on ITS sequence also supports its treatment as a new variety of I. piufanensis.
