  • Impatiens is a highly diversified genus with remarkable zygomorphic flowers. Floral ontogeny of three species of Impatiens has recently been studied, which suggested that, during the course of evolution, the anterolateral sepals become reduced and that these rudimentary sepals fuse postgenitally or congenitally with the anterior petal. All three belong to the majority type with five carpels and no mature anterolateral sepals. However, a few species of Impatiens have four carpels and two well… CONTINUE READING
