Discussion
Althaea armeniaca is very similar to A. officinalis and is known to hybridize with it. Althaea armeniaca differs primarily by the more deeply five-lobed leaves rather than the three in A. officinalis and can be distinguished from A. cannabina by its pubescent fruits. Only a single population is known from the flora area, found in Hutchinson County, near Lonetree Creek west of Olivet. The species dominated a fence row at the edge of a field and was locally common in scattered clumps over an area of about three miles.
