Several, see text Iliamna is a small genus of flowering plants in the mallow family, endemic to North America.

It is related to the bush mallows of California (Malacothamnus) and to Phymosia of Mexico, Central America and the Caribbean.

The name of the genus, proposed by Edward Lee Greene, appears to be a reference to Iliamna Lake in Alaska, even though the genus Iliamna does not occur in Alaska [1] The plants are herbaceous with a racemose inflorescence consisting of showy, slightly fragrant flowers ranging in color from almost white to lavender.

Iliamna remota was first reported by the Reverend E. J. Hill on June 29, 1872, on Langham Island in the Kankakee River of northern Illinois.

Reverend Hill noted that the plants grew in habitats he called "gravelly island" and "dry banks".
