M. Beardsley and R. G. Olmstead 2002; Beardsley et al. 2004; Beardsley and W. R. Barker 2005; Barker et al. 2012). In addition to those in North America, six <i>Mimulus</i> species are natives of the Eastern and Southern hemispheres; these include M. aquatilis A. R. Bean (northeastern Australia), M. bracteosus P. C. Tsoong (southeastern China), <i>M. gracilis</i> R. Brown (Australia), M. madagascariensis Bentham (Madagascar), M. orbicularis Wallich ex Bentham (mainland Southeast Asia), and M. strictus Bentham (Africa, India). Only <i>M. gracilis</i> and <i>M. ringens</i> have been subject to molecular analysis, but morphological similarities among these species indicate that they are monophyletic (Barker et al.).</p><!-- --><p>The clade including strictly defined <i>Mimulus</i> is sister to the essentially western American monkeyflower species, which are treated here within separate genera. These can be divided into two groups: those with axile placentation and with long pedicels (<i>Erythranthe</i>) versus those with parietal placentation and short pedicels (<i>Diplacus</i> and <i>Mimetanthe</i>). Molecular data confirm that <i>Erythranthe</i> and <i>Diplacus</i>/<i>Mimetanthe</i> are in separate lineages and are not the closest relative of each other. Closest to <i>Diplacus</i> and <i>Mimetanthe</i> is the Mexican-Central American Hemichaena Bentham, also with parietal placentation. Closest to <i>Erythranthe</i> is the monospecific Leucocarpus D. Don of Central America to northern South America, which has axile placentation.</p><!-- --><p><i>Mimulus alatus</i> and <i>M. ringens</i> maintain strongly distinct morphologies over a broad region of sympatry, but the two have been reported to hybridize naturally along the Patapsco River in Maryland (D. R. Windler et al. 1976). In a mixed population, about 40 percent of the individuals apparently were F1 hybrids; consistently high pollen stainability of the parental plants suggests that backcrossing was not occurring. The two species differ in chromosome number (<i>M. alatus</i>, 2n = 22; <i>M. ringens</i>, 2n = 16, 24), but chromosome numbers were not determined in this study.</p> |tables= |references={{Treatment/Reference |id=beardsley2004a |text=Beardsley, P.
