| The floral morphological and developmental patterns in three species of Impatiens (Balsaminaceae), namely I. columbaria, I. hawkeri, and I. niamniamensis, were studied to contribute to a better understanding of floral evolution in the genus. Strangely enough, the highly diverse floral morphology and ontogeny of this horticulturally important genus have never been studied thoroughly (e.g., using scanning electron microscopic techniques). We discuss the position and the developmental sequence of the different perianth members. We hypothesized that in the course of evolution, the anterolateral sepals become reduced and that a morphocline can be recognized going from species with five sepals, over species with rudimentary sepals that fuse postgenitally with... |

| A revision of the Balsaminaceae of Myanmar is presented based on herbarium collections and a field trip in 2015. Sixty-five species, unevenly distributed across one monotypic (Hydrocera) and one species-rich genus (Impatiens), are recognised. An identification key to species is presented. Twenty species are new records for the country, 17 names are typified and seven species names are synonymized. For each species, a description of the morphology, phenology, ecology and distribution range is provided. |
