| 説明 | silver arnica, Arnica chamissonis var. incana, California, White Mountains, McAfee Meadow, McAfee Creek, Fishlake Valley drainage, elevation 3568 m (11705 ft).The White Mountains representatives of this species seem a little different from populations elsewhere, being uniformly shorter with fewer pairs of leaves, and sometimes being mistaken for Arnica parryi. The best fit appears to be a variant of var. incana, which otherwise occurs in wet places mainly along the Sierra Nevada and Cascade axis, eastward irregularly into the Great Basin. Like so many other species, it reaches its highest elevation limit here in the White Mountains, but also extends well down through the subalpine zone in appropriate habitats. |
