Dist: NB and ME west to MN, south to GA, AR, and se. TX. The distribution as mapped here is somewhat speculative because of general historic lack of recognition.
ID notes:The combination of singly borne flowers on well-spaced inflorescence branches and large diffuse heads, make this among the more diagnostic species of the section. Distinguished from J. dichotomus, J. dudleyi, and J. interior by the long membranous auricle.
