Abstract
Impatiens is a diverse genus within the Balsaminaceae family, comprising over 1,120 species. The northern Gayo Plateau of Sumatra, an island in Southeast Asia, is renowned for its rich Impatiens diversity. In this paper, we described and illustrated a new species named Impatiens bungeusing from this area. This species is most similar to Impatiens vitellina Grey-Wilson but differs in having the distinct abaxial leaf venation in a dry state (vs obscure), lateral sepals falcate-oblong (vs narrowly lanceolate), lower sepals with U-shaped spur (vs straight), broadly ovate dorsal petal (vs ovate), and ovate sub-rhomboidal upper lateral united petals (vs oblong). This discovery brings the total number of known Impatiens species in Sumatra to forty-eight.
