Abstract
Impatiens cardamomensis S. H. Cho, C. K. Lim & H. Won, a new species of the family Balsaminaceae from the Cardamom Mountain Range in southwestern Cambodia, is described and illustrated. The species is similar to I. noei from Thailand in that it possesses solitary flowers, fusiform capsules, and compressed seeds, but is readily distinguished by its ovate to widely ovate leaves, shorter petioles, widely elliptic dorsal petals and smaller seeds.
Keywords: Cardamom Mountain range, new species, Impatiens, Cambodia

Impatiens cardamomensis S. H. Cho, C. K. Lim & H. Won, sp. nov.
Diagnosis: Impatiens cardamomensis is most similar to the Thailand endemic species I. noei Craib in habit but is readily distinguished from the latter by the ovate to widely ovate leaves, shorter petioles, widely elliptic dorsal petals and smaller seeds (Table 1).
Distribution: Knong Krapeur Mt. in the Cardamom Mountain Range of Cambodia (Kampong Speu Prov., Koh Kong Prov.)
Habitats: Impatiens cardamomensis grows on sandstone tables in evergreen forest margins at 900 m a.s.l.. Endemic to Cambodia, I. cardamomensis is at present known only in the type locality.
