Iliamna grandiflora
Iliamna angulata. Synonym: Iliamna grandiflora. (Wild Hollyhock)
Malvaceae (Mallow Family)

Foothills, montane. Streamsides, wet areas. Summer.
Mesa Verde National Park, Prater Ridge Trail, June 17, 2006.

These four foot tall beauties surprised us in the midst of charred Gambel's Oaks on a dry Mesa in Mesa Verde National Park in one of the driest years on record.  These are wetland loving plants, so the plants pictured must be tapping into moisture kept near the surface by rock. 

As the map below indicates, Iliamna angulata is rare in Colorado, and it is found only on the West Slope. It is also found in a few counties of Utah, Arizona, and New Mexico. 

Edwin Greene named the *Iliamna genus in 1906, renaming David Douglas' Malva rivularis to Iliamna rivularis.

A species very similar to Iliamna rivularis was discovered by F. K. Vreeland in Mancos Canyon at **Mesa Verde on June 20, 1901. In 1904 Vreeland's new species was named Sphaeralcea grandiflora and described by Rydberg. Wiggins renamed Vreeland's species Iliamna grandiflora in 1936 and that named was accepted universally until about 2020 when the name was changed to Iliamna angulata, a name given by Greene in 1906 for a plant collected by Alice Eastwood in the Uncompahgre Canyon of Colorado in 1887. Click to see Eastwood's collection which was identified by Eastwood as Sphaeralcea acerifolia, a name changed (as just noted) by Greene to Iliamna angulata.

*No one knows why Greene chose the name Iliamna. "Angulata" is Latin for "having angles".

**It should be noted that the 50,000 acre Mesa Verde National Park did not come into existence until 1906 so when Vreeland indicated "Mesa Verde", he was referring to the entire 150,000 acre mesa, all of which was part of the Ute Mountain Ute Indian Tribe Reservation.
