''Erythranthe'', the monkey-flowers and musk-flowers, is a diverse plant genus with more than 120 members (as of 2022) in the family Phrymaceae. ''Erythranthe'' was originally described as a separate genus, then generally regarded as a section within the genus '' Mimulus'', and recently returned to generic rank. ''Mimulus'' sect. '' Diplacus'' was segregated from ''Mimulus'' as a separate genus at the same time. ''Mimulus'' remains as a small genus of eastern North America and the Southern Hemisphere. Molecular data show ''Erythranthe'' and ''Diplacus'' to be distinct evolutionary lines that are distinct from ''Mimulus'' as strictly defined, although this nomenclature is controversial. Member species are usually annuals or

perennials. Flowers are red, pink, or yellow, often in various combinations. A large number of the ''Erythranthe'' species grow in moist to wet soils with some growing even in shallow water. They are not very drought resistant, but many of the species now classified as ''Diplacus'' are. Species are found at elevations from oceanside to high mountains as well as a wide variety of climates, though most prefer wet areas such as riverbanks. The largest concentration of species is in western North America, but species are found elsewhere in the United States and Canada, as well as from Mexico to Chile and eastern Asia.

Description

''Erythranthe'' is a highly diverse genus with the characteristics unifying the various species being axile placentation and long

s. Other characteristics of species can vary widely, especially between the sections, and even within some sections. Some species of ''Erythranthe'' are annuals and some are perennials. Flowers are red, pink, purple, or yellow, often in various combinations and shades of those colors. Some species produce copious amounts of aromatic compounds, giving them a musky odor (hence "musk-flowers"). ''Erythranthe'' is used as food by the larvae of some

species, such as the mouse moth (''Amphipyra tragopoginis''), as a main part of their diet. Within the section ''Erythranthe'', stems and leaves range from glabrous to hirsute, and are generally glandular. Leaves can be oblong, elliptical, or oval, with small tooths. Fruiting

s are longer than calyces. Calyces have sharp, definite angles and flat sides. Corollas are deciduous, relatively large (tube-throat long), and strongly red to purplish, magentarose, pink, or white, rarely yellow. ''Erythranthe guttata'' is the most widespread of the genus ''Erythranthe'' and its characteristics are fairly representative of the genus. ''E. guttata'' is tall with disproportionately large long, tubular flowers. Leaves are opposite and oval, long. The species as strictly defined is perennial and spreads with stolons or rhizomes. The stem may be erect or recumbent. In the latter form, roots may develop at lower leaf nodes. Sometimes dwarfed, it may be hairless or have some hairs. Leaves are opposite, round to oval, usually coarsely and irregularly toothed or lobed. The bright yellow flowers are born on a

has five lobes that are much shorter than the flower. Each flower has bilateral symmetry and has two lips. The upper lip usually has two lobes; the lower, three. The lower lip may have one large to many small red to reddish brown spots. The opening to the flower is hairy. The fruit is a two-valved capsule long, containing many seeds. '' Erythranthe alsinoides'' is similar to several species found in the Pacific Northwest. It is an annual herb that blooms from April–June with a preference for shady and moist dense habitats. The plant is hairy to slightly hairy and grows from tall. The stems are often reddish. The leaves are opposite and have a few prominent upper veins. Blades are long. The petiole is about the same length. The flowers are yellow with reddish-brown spots, usually on the lower lip, and the upper and lower lips have fused, growing . Each flower is attached by a

. The fruits are capsules.

Etymology and taxonomy

The derivation of ''Erythranthe'' is from Greek ἐρυθρός ("''erythros''"), red, with ἄνθος ("''anthos''"), flower. They are called monkey-flowers because some species have flowers shaped like a monkey's face. The widely used generic name, Latin ''mimus'' meaning "mimic actor", from the Greek ''mimos'' meaning "imitator" also alludes to the fancied monkey resemblance. The stem of ''Erythranthe'' can be either smooth or hairy, and this is known in a few species to be a trait determined by a simple

established ''Erythranthe'' as a separate genus with just the type species ''Erythranthe cardinalis''. In 1885, American botanist Edward Lee Greene classified ''Erythranthe'' as a section of '' Mimulus'' while adding ''E. lewisii'' and ''E. parishii''. In the 2012 restructuring of ''Mimulus'' by Barker ''et al''., based largely upon DNA evidence, seven species were left in ''Mimulus'' as strictly defined; ''Erythranthe'' was greatly enlarged to include 111 species, based upon axile placentation and long pedicels, 46 placed into ''Diplacus'' (species with parietal placentation and sessile flowers), two placed in '' Uvedalia'', and one each placed in '' Elacholoma'', '' Mimetanthe'', and ''

''. All of the American genera are still referred to as "monkey-flowers". Views on the evolutionary position of the monkey-flower species have changed. It was long considered to be in the family Scrophulariaceae, but is now placed in Phyrmaceae, primarily on the basis of DNA evidence. The genus '' Phryma'' (comprising only a single species), for which the family is named, is considerably different in morphology from all of the monkey-flowers.. Attempts at crossing species, whether from different sections or within the same section, of ''Erythranthe'' are not always successful. '' E. peregrina'' is an example of a successful naturally occurring hybrid that not only arose independently in two different locations, but is also a rare example of evolutionary recent allopolyploidization, complete chromosomal inheritance. Charles Darwin's 1876 study of inbreeding depression and self-fertility in South American species was a progenitor for the study of ''Erythranthe'' biology. The genus has become a model system "for studies of evolutionary and ecological functional genomics ...

of ''E. guttata'' was released in late spring, 2007. Many issues remain in ''Erythranthe'' taxonomy. ''E. guttata'' is highly complex, with many variations apparently reflecting differences in geographic environment and elevation. Molecular geneticists regard the species broadly as including both perennial and annual populations, but there is rationale for treating this complex as several distinct species (perennials are ''E. guttata'', ''E. grandis'', and ''E. corallina''; annuals are ''E. microphylla'' and others). The perennials and annuals differ as groups from each other by an inversion sequence on chromosome 8. Evidence tentatively indicates that the perennials evolved from annual ancestors, although some evidence has been interpreted to indicate that ''E. nasuta'' evolved from ''E. guttata'' in central California between 500,000 and 200,000 years ago and since then become primarily a self-pollinator. Relationships among the apparently closely related ''E. tilingii'', ''E. minor'', and ''E. caespitosa'' are not clearly understood. Some currently recognized species may be just variants of other species: ''E. arenicola'', ''E. brachystylis'', ''E. regni''. Chromosomal issues may affect the classification of some species: ''E. corallina'', ''E. guttata'', ''E. nasuta'', ''E. tilingii'', and ''E. utahensis''.

Reproductive biology

Before recognition of ''E. cinnabarina'' as a species, ''E. lewisii'' was interpreted to be the sister of ''E. cardinalis''. It is now clear that ''E. cinnabarina'' and ''E. cardinalis'' are sister species and that ''E. lewisii'' and ''E. erubescens'' are sister species. In the hypothesized phylogeny, the 'cinnabarina/cardinalis' pair is sister to the 'lewisii/erubescens' pair. ''Erythranthe lewisii'' is a model system for studying pollinator-based

. This approximate ratio of insect vs hummingbird pollination holds true for the rest of the genus. There have been two separate transformations to hummingbird pollination. Pollination changes are highly affected by changes in flower morphology. ''E. cardinalis'' and its sister species ''E. cinnabarina'' likely evolved via allopatric speciation. ''Erythranthe guttata'' is pollinated by bees, such as '' Bombus impatiens''. Inbreeding reduces flower quantity and size and pollen quality and quantity.

Members of this genus are found in eastern Asia; several species of which have a high degree of similarity with some of the species found in North and South America. A large number of the species grow in moist to wet soils with some growing even in shallow water. They are not very drought resistant, but the species now classified as ''Diplacus'' are. Some species grow in dry areas, others in wet habitats, such as members of the section ''Simiolus'', which are hydrophilic. Both overall plant size and

Human culture

Horticulture

In horticulture, several species, cultivars and hybrids are used. Because of their wide range and many variations, the most important are those derived from ''E. gutatta'' and ''E. lutea''. ''E. cuprea'' alone has at least 10 cultivars and hybrids.

and other salts absorbed from the soils in which they grow in their leaves and stem tissues. Native Americans and early travelers in the American West used this plant as a salt substitute to season wild game. The entire plant is edible, but reported to be very salty and bitter unless well cooked. The juice from the leaves was used as a poultice for mild skin irritations and burns. Leaves can be used in salads and soups; flowers taste best before blooming. ''E. lutea'' has been used for cooking in Peru.
