The Kankakee globe-mallow was first described in 1906, and was originally found on an island in the Kankakee River in Illinois. In the 1920's it was recognized that this species was in danger of extinction, so seeds were collected and reportedly dispersed along railways in Illinois, Indiana, and Virginia. Since that time, populations have established and generally increased. This species was not known from Virginia before the 1920's, so it is theorized that it is there as a result of human-facilitated dispersal (Stewart and Porter 1995; Stewart et al. 1996).
There are eight species in the Iliamna genus, all of them native to North America. Six are found west of the Mississippi River, and two east. Iliamna rivularis var. rivularis (or Iliamna remota, as it is considered by some) and Iliamna corei are the two species east of the Mississippi, and both are considered rare and endangered.
This species grows to a height of 2 meters, with leaves that are shallowly 5- to 7-lobed, 15-20 cm long and nearly as wide. This globe-mallow produces fragrant, rose-purple flowers that are 4-6 cm in diameter. (Greene 1906)
