Various authors have treated some of these taxa within Althaea, but this disagrees with Linnaeus’s concepts of the two genera as quite distinct. The primary difference is that Alcea has a two-chambered mericarp (the upper chamber being empty and vestigial) and yellowish anthers, and Althaea has a one-chambered mericarp and purple or brownish-purple anthers. Current treatments consistently accept the two genera as distinct; see M. E. Uzunhisarcikii and M. Vural (2012) for a discussion of the two genera and their circumscriptions.</p><!-- --><p>Alcea biennis Winterl occasionally is planted and rarely is found as an escape. It differs from the two species treated here by its white to pink corolla with a pale yellow to greenish center and by its generally more deeply lobed petals that are usually more separated and less overlapping. Its involucel is more than one-half as long as the calyx, sometimes equal in length, the sepals are conspicuously striate, the pedicel is 1–25 mm long, and the mericarps are conspicuously winged; its leaves are inconspicuously lobed or merely angled.</p><!-- --><p>Species ca. 70 (2 in the flora).</p> |tables= |references= }}<!-- --><div class="treatment-key"> ==Key== <div class="treatment-key-group"> {| class="wikitable fna-keytable" |-id=key-0-1 |1 |Leaf blades angled or shallowly lobed or rarely more deeply; flowers usually white, pink, red, or purple, rarely yellow, not drying greenish; involucellar bractlets 1/2+ calyx length. |[[Alcea rosea|Alcea rosea]] |-id=key-0-1 |1 |Leaf blades lobed usually halfway or more to midrib, often figlike; flowers pale yellow, usually drying greenish; involucellar bractlets usually 1/2–2/3 calyx length. |[[Alcea rugosa|Alcea rugosa]] |} </div></div><!-- -->{{#Taxon: name=Alcea |author=Steven R.
