The perennial species generally have stellate pubescence and the annual species generally have simple hairs; both have pink to purple anthers; the annuals are thought by some to be better placed within the genus Malva. Althaea is very similar to Alcea, and the latter has been combined with it by various authors. Hybrids between the two (×Alcathaea Hinsley) have been described, as have hybrids between Malva and Althaea (×Malvalthaea Iljin). See discussion under 13.
