|discussion=<p>Of conservation concern.</p><!--
--><p>In Texas, Erigeron vicinus grows in the Davis Mountains, Jeff Davis County. In its fibrous-rooted habit and perennial duration, finely strigose distal stems, and simple or branched stems with heads on relatively long peduncles, E. vicinus is similar to E. pubescens Kunth, a species occurring throughout much of the northern half of Mexico but apparently not reaching the United States, and to forms of E. modestus (especially with respect to the stems reddish and pilose at bases). Erigeron vicinus was originally described from the Sierra Madera del Carmen of Coahuila, where it was thought to be endemic.</p>
