Impatiens bungeusing (Balsaminaceae), a new species from the Northern Gayo Plateau, Sumatra, Indonesia 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.

Impatiens bungeusing（毛茛科，Impatiens属），一种来自苏门答腊岛北部加约高原的新物种。Impatiens属在毛茛科中种类繁多，包含超过1,120种。东南亚的苏门答腊岛北部加约高原以其丰富的Impatiens属多样性而闻名。在本研究中，我们描述并展示了该地区的一种新物种，命名为Impatiens bungeusing。该物种与Impatiens vitellina Grey-Wilson最为相似，但存在明显差异：在干燥状态下，其叶脉腹面清晰可见（而非模糊），侧萼片呈镰刀状长椭圆形（而非狭长形），下萼片具U形距（而非直），背瓣阔卵形（而非卵形），以及上侧合瓣呈卵形亚菱形（而非长形）。这一发现使已知苏门答腊岛Impatiens属物种总数达到四十八种。
