Discussion | Earlier segregation of Erythranthe moniliformis as distinct from E. moschata (for example, G. L. Nesom 2012g) emphasized a primarily erect habit and tendency toward sessile to subsessile and more densely arranged cauline leaves in E. moniliformis versus a decumbent to procumbent habit and consistently petiolate leaves on longer internodes in E. moschata. Discontinuities in morphology, geography, and ecology were not confirmed in later study by Nesom (2017). Rhizomes with small, tuberlike swellings can be observed over the whole moschata/moniliformis range, and there apparently are no consistent distinctions in vestiture and corolla size. Mimulus acutidens Reiche (1911), a later homonym of M. acutidens Greene, pertains here. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Genera 13, species ca. 200 (6 genera, 139 species in the flora). Over one half of the species in Phrymaceae are members of Diplacus and Erythranthe and together include over 160 species; all other genera each have seven or fewer species. Until recently, Phrymaceae consisted only of Phryma leptostachya, a taxonomically isolated species of eastern North America and eastern Asia. Molecular studies have established a relationship not with the Verbenaceae, as was earlier postulated (see H. L. Whipple 1972; R. Venkata Ramana et al. 2000), but rather with Mimulus and other genera, suggesting that Phrymaceae should be enlarged. The sequence of genera in Phrymaceae here follows the phylogeny proposed by P. M. Beardsley and R. G. Olmstead (2002). One of the major lineages of Phrymaceae is primarily a Southern Hemisphere group ranging from Australia and New Zealand to southeastern and south Asia (India), Madagascar, and South Africa. Mimulus in the narrow sense, including the two endemic North American species, is part of this group, which includes 24 species in seven genera. The largest major lineage includes 158 species in five genera from North America, South America, and southeast Asia. This lineage includes two genera from Mexico and Central America: Hemichaena Bentham, which is sister to the North American Diplacus and Mimetanthe, and Leucocarpus D. Don, which is sister to the American and Asian Erythranthe. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
