Distribution

"NV, UT, and AZ, east to KS, OK, and TX; south to MEX. Notes: Erigeron is a difficult genus, with many similar looking species distingushed from each other by subtle and obscure characters. A hand lens is necessary for field ID, and making a collection is generally advisable in order to have any confidence in a determination. Identify the genus as a whole from its characteristic daisy-like flowers with white to pale purple rays and yellow centers (although a few species have extremely small rays); involucres with 2-5 series of phyllaries, all about the same length (subequal); and tufts of bristles on the tops of the seeds. E. tracyi is quite similar to the common and widespread E. flagellaris; E. tracyi can be distinguished by the denser spreading hairs on its stems and flower stalks (E. flagellaris has appressed hairs); its slightly woody base; and the fact the stolons rarely root at the tips." (SEINet)


Description

Erigeron tracyi combines characteristics of Erigeron divergens and Erigeron flagellaris.   The overall appearance of the plant is that of the former and the stolons (runners) are similar to those of the latter.  A Utah Flora and Intermountain Flora consider  E. tracyi to be a variety of E. divergens, but The Flora of North America, the Synthesis, and Weber consider E. tracyi to be a distinct species. Erigeron trayci certainly has a number of characteristics that are distinct from those of E. divergens: E. trayci is often perennial; E. divergens is annual. E. trayci has long and obvious stolons; E. divergens does not have stolons.
