Discussion	Erythranthe filicaulis is known only for certain from Mariposa and Tuolumne counties. Kappler 1691 (UCLA) from Madera County also may be this species.

In addition to the features noted in the key and descriptions, the fruiting calyces of Erythranthe grayi are distinctly more inflated than those of E. acutidens and E. inconspicua. G. L. Nesom (2012g) maintained E. grayi as distinct from E. acutidens, relying primarily on fruiting pedicel length (see key above), but the two have nearly identical ranges (Tuolumne County south to Kern County), and study of additional collections suggests that only a single species may be represented.
