Discussion | Dodecatheon poeticum grows mainly in the Columbia River gorge and on the eastern edge of the Cascade Range in Washington, and in Oregon. Nearby one can find D. conjugens var. conjugens and D. pulchellum var. cusickii, features of which (the rugose connective of the former, the glandular condition of the latter) are combined in D. poeticum. The distinct filaments of var. conjugens readily distinguish that taxon from D. poeticum; distinction between D. poeticum and D. pulchellum var. cusickii is difficult. The former has maroon pollen sacs; var. cusickii has yellow ones. Plants with all of the features of D. poeticum rarely have the smooth connective typical of D. pulchellum. H. J. Thompson (1953) suggested that D. poeticum (a tetraploid) might be the product of an allopolyploid involving var. cusickii and D. hendersonii (both diploids). The leaves of Dodecatheon poeticum are occasionally slightly toothed and relatively broad (e.g., K. L. Chambers 2080, OSC) and resemble the leaves of D. dentatum, a species that flowers in the Gorge typically after D. poeticum. Rootstocks with bulblets are rarely seen on herbarium specimens.

Dodecatheon redolens occurs mainly in the high mountains of the southern Sierra Nevada, with scattered populations in the San Bernardino, San Gabriel, and San Jacinto mountains of southern California. Elsewhere in California, it occurs on scattered desert ranges in the northern Mojave Desert. In the Intermountain West, it is found occasionally in Inyo and Mono counties on the eastern foothills of the Sierra Nevada, the White Mountains, and on or near Glass Mountain. It is found across central Nevada to the Independence and Ruby mountains of Elko County, and the Deep Creek Range of west-central Utah. Although difficult to see, a fairly good feature of Dodecatheon redolens is that the corolla tube usually covers the filaments and proximal end of the anthers. In both D. jeffreyi and D. alpinum, the corolla tube does not cover the base of the anthers. In addition, the tips of the anthers in the latter two species are truncate to obtuse; in D. redolens they are acute. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
