--><p>In a genus of primarily mesophytic plants, Thalictrum heliophilum is notable for its relatively xeric habitat. Known only from Garfield and Rio Blanco counties, northwestern Colorado, it is similar to the widespread T. fendleri; it may be distinguished by its smaller, leathery, glaucous leaflets and fewer achenes.</p>
