Tragopogon miscellus Ownbey

Tragopogon miscellus has been reported from near Gardiner, Montana; it is no longer present there.

Plants of Tragopogon miscellus are larger and more robust than those of T. pratensis. They are allote-traploids, formed (probably repeatedly) from hybrids between T. pratensis and T. dubius. Outer florets are shorter than the phyllaries except at some sites in Pullman, Washington, where outer florets equal or surpass the phyllaries. (The different inflorescence morphs result from reciprocal polyploid origins.) F1 hybrids between T. dubius and T. pratensis (= T. ×crantzii Dichtl) may resemble T. miscellus but are less robust, have low pollen stainability, and set few, if any, seeds. Tragopogon miscellus does not occur in Europe, but hybrids between T. dubius and T. pratensis occur occasionally.

Plants 60–150+ cm. Leaves: apices usually recurved to coiled, faces initially floccose to tomentulose, soon glabrescent. Peduncles distally inflated. Involucres conic to urceolate in bud. Outer florets usually slightly shorter than phyllaries (see discussion for exception); corollas yellow. 2n = 24.

Tragopogon miscellus, the Moscow salsify, is a species native to the States of Washington and Idaho. Intensive studies over the course of many years have demonstrated that it originated as an allopolyploid hybrid between T. dubius and T. pratensis, both of which are European species naturalized in the US. Tragopogon miscellus has become established in the wild, reproducing by its own, thus deserving recognition as a species.

Tragopogon miscellus is an herb up to 150 cm (60 inches) tall. Leaves are slightly tomentose when young, nearly glabrous when mature, with a tip that is recoiled (curved backwards). Flowers are yellow.
