| 説明 | Heller birdbeaks, Cordylanthus kingii subsp. helleri, Nevada, White Mountains, Mustang Mountain, Sagehen Flat, Pinchot Creek - Columbus Salt Marsh watershed, elevation 2905 m (9530 ft).This species is a spring or summer annual typical of the understory of pinyon-juniper woodlands and adjacent sagebrush vegetation, and is found throughout most of the Great Basin and almost all of Utah. Heller birdbeaks is the subspecies limited to the southwest corner of this range, from central Nevada westward into the Great Basin portion of eastern California. It reaches higher elevations, and is characterized by shorter flower parts, including more numerous bracts with shorter and broader lobes. The plants also tend to be more copiously glandular hairy.All Cordylanthus species are considered to be hemiparasitic, possessing chlorophyll but also deriving some of their nutrients from the roots of other associated species. As plants of Heller birdbeaks develop, the chlorophyll is rapidly lost or masked by brownish purple pigments, lending pinyon-juniper woodlands a characteristic understory color after especially wet spring or summer seasons. |
