Discussion | No natural occurrences of Erythranthe inflatula are known from Washington; the type collection from Klickitat County is from a cultivated plant. Morphological and molecular data (R. J. Meinke 1995; P. M. Beardsley et al. 2004) indicate that Erythranthe inflatula originated as a hybrid between E. breviflora and E. latidens. Its geography and biology suggest that it is reproductively stable. The putative parents are geographically and ecologically separated for most of their ranges, and the range of E. inflatula is considerably broader than the relatively small region where the parents are sympatric. In the region of sympatry, however, E. inflatula may be difficult to distinguish from one or both of its putative parents. G. L. Nesom (2012g) was not able to find morphology that would distinguish the recently described Mimulus evanescens from E. inflatula.
