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