Aletes humilis is a species of flowering plant in the carrot family known by the common names Colorado aletes and Larimer aletes. It is native to Colorado in the United States; it is also known from Wyoming, but there are no recent collections there.[1]
, Plants of the World Online regarded Aletes as a synonym of Cymopterus,[2] but did not provide a name in that genus for Aletes humilis, stating only that the name is a synonym.[3]
This plant forms a mound or cushion up to 10 centimeters tall by 20 wide. The thick, leathery, bright green leaves have toothed edges.[1] [4] The leaves have a celery-like or "soapy" scent.[5] The short inflorescence has yellow flowers.
This plant grows in cracks and crevices on rock outcrops and cliffs. The habitat is dry.[4] The vegetation is a sparse mix of ponderosa pine (Pinus ponderosa) and Douglas-fir (Pseudotsuga menziesii). Other plants in the habitat include quaking aspen, fivepetal cliffbush kinnikinnick, common juniper, wax currant, littleflower alumroot, bigflower cinquefoil, mountain muhly, and needle and thread grass.[5]
