M. F. Baad (1969) considered Eremogone kingii to be monophyletic despite considerable morphological variation; J. C. Hickman (1971) thought otherwise, considering E. kingii to be a “genetic dumping ground for all the closely related taxa,” but did not propose any new taxonomic alignment.
Eremogone kingii is extremely variable throughout its range with six infraspecific taxa recognized (under Arenaria kingii) by B. Maguire (1947, 1951). We have been unsuccessful in distinguishing more than two of those taxa. The others intergrade to such an extent that formal recognition is unwarranted. Most distinctive of these here-rejected taxa is var. uintahensis, said to have sepals (4.5–)5–6 mm, versus 3.6–4.5(–5) for the other taxa. Interestingly, the type specimen has sepals mostly 4.5 mm long. In the main portion of the range of var. uintahensis, the sepals are rounded to broadly obtuse, but they may also be acute. Furthermore, the sepals and pedicels are often glabrous, but the correlation of the above-mentioned characters varies over the range.

Eremogone aberrans is known only from northern Arizona and resembles a robust form of the more northerly occurring E. aculeata. In Arizona it is often confused with E. fendleri, which has sepals more or less glandular-pubescent whereas E. aberrans has sepals glabrous or with a few glandular hairs at their bases.
