Chrysosplenium iowense is a species of flowering plant in the saxifrage family known by the common name Iowa golden-saxifrage. It is native to North America, where it is "primarily a Canadian species", occurring from the northern Northwest Territories south to British Columbia and east to Manitoba.[1] There are also disjunct,[1] relictual[2] occurrences within the United States, in the Driftless Area of Minnesota and Iowa.[3]
Chrysosplenium iowense is a small easily unnoticed plant with upright hairless stems.[4] It is stoloniferous, with thin stolons and stems up to 15 centimeters tall.[2] Flowering stems are not produced during the first season.[1] Leaves occur on the stolons and the stems. The leaves are alternately arranged on the stems, with the lower leaves roundish in shape with seven to eleven lobes.[4] The top two leaves are adnate (joined together) to the inflorescence branches. The inflorescence is a cyme of up to 12 flowers with leaflike yellow-green bracts and small yellow or greenish sepals.[2] The flowers have yellow anthers. The production of flowers varies by temperature, with the maximum flowering occurring when the substrate is around 11 to 12 °C.[1] Plants require insects for pollination.[3] The cuplike fruit capsule contains many reddish seeds.[2]
