Discussion

Although first described as a separate species, Diplacus calycinus has more recently been treated at subspecific or varietal rank (A. L. Grant 1924; F. W. Pennell 1951; P. A. Munz and D. D. Keck 1973). D. M. Thompson (2005) included both D. calycinus and D. longiflorus within his concept of Mimulus aurantiacus var. pubescens (Torrey) D. M. Thompson. He did not reference the study of sect. Diplacus by M. C. Tulig (2000), but results from the Tulig morphometric analyses indicated that D. calycinus is distinct from D. longiflorus, especially in corolla length, corolla tube length, and style length.

The type of Diplacus calycinus is from Tulare County, and the concept of the species is perhaps best restricted to the Sierran population system in Fresno, Kern, and Tulare counties, disjunct from D. longiflorus, which occurs primarily in coastal counties. The Sierran system is characterized by distinct abaxial leaf vestiture; the hairs are unbranched, broad, and vitreous, compared to the branched, thinner, and dull hairs of D. longiflorus. Plants of D. calycinus parapatric with D. longiflorus also show a tendency toward the characteristic vestiture and also have lighter-colored (but more variable in color) corollas with narrower but slightly shorter tubes. Intergradation between D. calycinus and D. longiflorus occurs in the region connecting the San Bernardino and San Gabriel mountains in San Bernardino County.
