Summary of Invasiveness

Top of page

As many other species within the genus Emilia, E. coccinea is herb that behaves as an environmental and agricultural weed. This fast-growing herb has the potential to rapidly colonize disturbed areas, waste grounds, gardens, forest edges, pastures, active and abandoned cultivated lands, roadsides, dry thickets and riverbanks. This species is adapted to grow in a wide range of environmental conditions and has wind-dispersed seeds, which are features that may facilitate its spread into new habitats. It is listed as invasive in Hawaii, Dominican Republic and New Caledonia.

Notes on Taxonomy and Nomenclature

Top of page

With 1,620 genera and more than 23,600 species, Asteraceae is one of the most diverse families of flowering plants (Stevens, 2018). Emilia is a palaeotropical genus of annual and perennial herbs comprising about 116 species, the majority of which (ca. 80 species) occur in Africa and Madagascar, but also across Asia and the Neotropics (Jeffrey, 1986; 1997; Lisowski, 1991; Davidse et al., 2018).

Emilia coccinea is a widespread and morphologically variable complex of species from tropical and subtropical Africa. Emilia coccinea was first described in 1803 as Cacalia coccinea from a plant cultivated in London. However, no specimen was preserved and in 1839 the name Cacalia coccinea was changed to Emilia coccinea. The species grouped in the E. coccinea complex are annual herbs, with relatively large capitula  (for the genus; 5–8 mm diameter) and red, orange, or yellow florets (Mapaya and Cron, 2016).

Different revisions and taxonomic studies of the E. coccinea complex have resulted in the identification of about 8 - 14 species, with E. coccinea sensu stricto restricted to eastern and southern tropical Africa (Jeffrey, 1997; Lisowski, 1991; Mesfin Tadesse and Beentje, 2004; Cron, 2014). However, recent multivariate and cluster analyses of the E. coccinea complex have recognized five species (E. emilioides, E. jeffreyana, E. praetermissa, E. subscaposa, E. vanmeelii) as morphologically distinct species (Mapaya and Cron, 2016).

Description

Top of page

The following description is from Flora of China Editorial Committee (2018):

Herbs, annual. Stems erect, 40-70(-100) cm tall, glabrous or hispidulous. Basal and lower leaves shortly petiolate; blade oblong, obovate, or subspatulate, 5-7 × 2-2.5 cm, both surfaces puberulent, veins convex abaxially and conspicuously concave adaxially, base gradually attenuate, winged and semiamplexicaul, margin entire or repand-denticulate, apex obtuse. Median stem leaves sessile, oblong or ovate-oblong, large, basally hastate and amplexicaul. Upper leaves smaller, lanceolate or oblong-lanceolate, basally auriculate and amplexicaul, apically acute.

Habitat

Top of page

Emilia coccinea is often cultivated as an ornamental in gardens and yards. It also grows in clearings, disturbed areas, lawns, moist hillsides, open areas, pastures, riverbeds, roadsides and dry thickets, at low elevations (e.g., from sea level up to 2,000 m). It is also a common weed in agricultural lands, coffee plantations and in abandoned cultivated lands and pastures (Davidse et al., 2018; Flora of China Editorial Committee, 2018; PIER, 2018; PROTA, 2018).

Biology and Ecology

Top of page

Genetics

The chromosome number for E. coccinea has been reported as either 2n = 10 and 2n= 20 (Flora of China Editorial Committee, 2018).

Reproductive biology

Emilia coccinea has bisexual flowers that are pollinated by insects (i.e. bees and flies) and by wind. This species is self-fertile (Davidse et al., 2018; PFAF, 2018).

Physiology and phenology

In China it flowers from July to November (Flora of China Editorial Committee, 2018). In Central America, it flowers from July to August (Davidse et al., 2018).

Longevity

Emilia coccinea is a fast-growing annual plant (Flora of China Editorial Committee, 2018).

Environmental requirements

Emilia coccinea prefers to grow in most, well drained soils in a sunny position with pH in the range 6.1 to 7.8. Plants are drought tolerant once established, but they need temperatures between 15°C to 22°C to thrive (Useful Tropical Plants, 2018; PROTA, 2018).

Emilia coccinea spreads by seed. Seeds are mostly dispersed by wind, but they can be secondarily dispersed by water, as a contaminant in soil and crop seed, adhered to vehicles and agricultural machinery and in dumped garden waste (Davidse et al., 2018; Flora of China Editorial Committee, 2018; PFAF, 2018; PROTA, 2018; Useful Tropical Plants, 2018).

Environmental Impact

Top of page

As a weed Emilia coccinea can impact agricultural land, pastures and gardens. It also grows as an environmental weed, outcompeting native plant species for common resources such as water, space, and light and thus negatively impacting native vegetation in secondary forests, forest edges and natural grasslands (Wagner et al., 1999; Mir, 2012; Davidse et al., 2018; PROTA, 2018; PIER, 2018).

Uses

Top of page

Social Benefit

Emilia coccinea is widely cultivated as an ornamental in gardens and yards across tropical, subtropical and temperate regions. In Africa, this species is sometimes gathered from the wild and used locally for food and as medicine. In traditional African medicine, the leaves are used to treat wounds, sores and sinusitis. Dried powdered leaves are also applied to sores. Roots or leaves are boiled and the decoction is used to treat syphilis and as a chest medicine (Useful Tropical Plants, 2018; PROTA, 2018).

Similarities to Other Species/Conditions

Top of page

Emilia coccinea can be confused with E. sonchifolia and E.fosbergii. These three species can be distinguished based on based on the following vegetative and floral traits (Davidse et al., 2018):

  • Emilia coccinea: Basal and lower leaves shortly petiolate; involucres broad-cylindrical to hemispherical, corollas moderately to well-exserted; corollas lobes 1.1-2.2 mm; disk floret styles obviously appendiculate, appendages 0.2-0.3 mm, caudate. Leaf margins nearly subentire; involucres campanulate, about as long as broad, corollas well-exserted; corollas bright orange to red, lobes 1.6-2.2 mm.

  • Emilia fosbergii: Basal and lower leaves shortly petiolate; involucres broad-cylindrical to hemispherical, corollas moderately to well-exserted. Leaf margins usually coarsely dentate; involucres broad-cylindrical, (1-) 2× as long as broad, corollas moderately exserted; corollas usually pale red or pinkish-red, lobes 1.1-1.6 mm.

  • Emilia sonchifolia:  Basal and lower leaves lyrate-pinnatifid; involucres narrow-cylindrical, corollas included to only slightly exserted; corollas usually pink or lavender, lobes 0.5-0.8 mm; disk floret styles indistinctly appendiculate, appendages to 0.1 mm, no longer than broad, convex.

Prevention and Control

Top of page

Due to the variable regulations around (de)registration of pesticides, your national list of registered pesticides or relevant authority should be consulted to determine which products are legally allowed for use in your country when considering chemical control. Pesticides should always be used in a lawful manner, consistent with the product's label.

Chemical control

There is no information available for the chemical control of E. coccinea.  However, herbicides such as dimethametryn, propanil, oxidiazon, metribuzin, imazaquin, diuron, simazine and paraquat have been used to control the closely related species E. sonchifolia (CABI, 2018).
