Synthyris missurica - Tailed Kittentails, Mountain Kittentails, Mountain Kittentoes. Synthyris species are found only in eight northwestern states, in Alaska, and in northwestern Canada. There are three subspecies of Synthyris missurica - ssp. hirsuta, found only in Oregon, ssp. stellata, found in Oregon and Washington, and the one presented here, ssp. missurica, found in those two states as well as northern California, Idaho, and Montana. It should be noted that ITIS lists a major subspecies, and does not accept the hirsuta subspecies. In the southern end of its range Synthyris missurica is found only in higher elevations. It is an early blooming plant, shortly following snow melt, or even while some snow is still on the ground.

Synthyris missurica is one of many species that have been moved out of the Scrophulariaceae family (figworts.) It has been moved to family Plantaginaceae (Plantains,) one of several families receiving species from the disintegrating Figwort family.

The flowers of Tailed Kittentails are a lovely mid- to deep blue. The two large stamens and the pistil stick out past the four petals (they are "exserted",) giving a fuzzy appearance to the raceme.

The fuzzy-looking dense raceme of blue flowers is reported to be the origin of the "kittentails" common name. While most of the leaves are basal, there are usually a few small leafy bracts on the scape, which is usually less than 10 inches tall, including the inflorescence.
