Abstract

Impatiens karenensis (I. sect. Semeiocardium) from Kayin State, Myanmar is described and illustrated here. It is most similar to I. micromeris, but differs in having lower petals with outer margins strongly undulate in the lower half (vs. lower petals entire), apex of upper petals acute to obtuse (vs. apex rounded), short stout spur, ± as long as the depth of lower sepal, ca. 2.5 mm long (vs. long attenuate spur, twice as long as the depth of lower sepal, ca. 5 mm long). Its conservation status is also assessed as Critically Endangered.
