Of conservation concern. Erigeron abajoensis is a segregate of E. caespitosus, separated from the latter only by its strigose (versus hirsute) stems and leaves and greater tendency for 1-nerved leaves. Further, some populations of E. abajoensis have plants variable in orientation of stem vestiture [both antrorsely appressed and deflexed; e.g., Cronquist 9430, Garfield Co., Utah (BRIT, NY); Heil and Clifford 17919, Apache Co., Ariz. (BRIT, SJNM)] and similar variation in cauline vestiture also occurs in E. caespitosus. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
