Description
Impatiens leshanensis X.H.Gu, K.Huang & Z.X.Fu, sp. nov., a new species of Balsaminaceae from Jinkouhe District, Leshan City, Sichuan Province, China, is described and illustrated. Phylogenetic analysis based on the complete cp genome indicates that the new species is closely related to Impatiens faberi Hook.f., forming a monophyletic clade. However, I. leshanensis can be distinguished from I. faberi and other morphologically similar species (including Impatiens baishaensis B.Ding & H.P.Deng, Impatiens piufanensis Hook.f., Impatiens forrestii Hook.f. & W.W.Sm, Impatiens distracta Hook.f., Impatiens lateristachys Y.L.Chen & Y.Q.Lu, Impatiens rostellata Franch., Impatiens rectirostrata Y.L.Chen & Y.Q.Lu, and Impatiens longcanggouensis Q.Luo.) by its unique morphological traits: oblong-elliptic dorsal petal as wide as the lateral petals, narrowly funnelform lower sepal, pale pink flowers with deep red spots and pink stripes, and ellipsoid seeds with reticulate ornamentation. Additionally, the distribution map and chloroplast genome features are provided.
