Description. This new genus resembles Omphalodes in nutlet shape and size, from which it can be distinguished by the apical attachment scar, the strongly incurved entire, wide and hollow margin of the nutlet with an air chamber, and the presence of smooth trichomes on both adaxial and abaxial sides of the nutlet. In addition, the more compact and globose pollen grains, and axillary inflorescence distinguish Memoremea from Omphalodes s.s.

Etymology. The Latin phrase “ Memore me ” which means “Remember me”, which would be complementary to “Forget-me-not”, the common name that refers to some species of the tribe Cynoglosseae in many languages, especially species of the genus Myosotis .
