Although the population of E. sneedii var. sneedii is distinct as a whole, it may be difficult to assign some plants in the population to a specific taxon without the aid of geographic information and this variation continues to present difficult taxonomic problems. For example, plants from the Guadalupe Mountains that intergrade between E. sneedii var. leei and E. guadalupensis are morphologically indistinguishable from E. sneedii var. sneedii of the Franklin Mountains (Baker and Johnson 2000).
The presence of this variety in the limestone ranges of adjacent Chihuahua needs to be determined.
