Desmodium incanum

Morphological description. Erect perennial herb or low shrub growing to 60 cm tall, but more typically prostrate and below 20 cm under grazing. Fibrous trailing stems from a deep well-branched root system; stems root readily at the nodes. Trifoliate leaves on petioles up to 3.5 cm long, with stipules 3–11 mm long by 1–3 mm wide. The leaflets are very variable, but mostly elliptical. The terminal leaflet may be up to 9 cm long and 4.5 cm wide with lateral leaflets up to 6 cm long and 3 cm wide, but generally the leaves on upper braches are larger and more pointed than those on the lower branches. The upper surface of the leaf is dark green, often with a paler streak along the midrib, but paler and densely pilose on the under surface.

The inflorescence is a terminal or axillary raceme , up to 20 cm long with single blue, red or purple flowers on standards up to 6 mm long. The flowers may also be in fascicles of 3.

The seed pods may be up to 4 cm long, with a straight upper margin and strongly indented lower margin, and are covered with hooked hairs. The light brown seeds are usually kidney shaped, 1 mm x 0.5 mm.

Scientific name. Desmodium incanum DC.

Family/tribe. Family: Fabaceae (alt. Leguminosae) subfamily: Faboideae, tribe: Desmodieae subtribe: Desmodiinae. Also placed in: Papilionaceae.

Common names. kaimi-clover, kaimi, creeping beggar weed; pega-pega (Portuguese, Spanish). 


Native to: North America: Mexico.

Mesoamerica: Belize, Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua, Panama.

Caribbean: Antigua and Barbuda, Bahamas, Barbados, Cuba, Dominica, Guadeloupe, Hispaniola, Jamaica, Martinique, Montserrat, Puerto Rico, St. Kitts and Nevis, St. Lucia, St. Vincent and Grenadines.

South America: Argentina, Bolivia, Brazil, Colombia, Ecuador, French Guiana, Guyana, Paraguay, Peru, Suriname, Venezuela.

Now widely distributed throughout the humid tropics and subtropics. It is abundant on volcanic soils in Hawaii and other Pacific islands.

Uses/applications. A potentially useful legume in heavily grazed pastures and on low to moderate fertility soils, as in rundown Brachiaria pastures in the Amazon Basin. No longer sown commercially. 


Soil requirements. Best adapted to fertile, neutral to alkaline soils but can be found on soil textures from sands to medium clays with pH from as low as 4.0.

Moisture. Adapted to regions with AAR between 1,500–3,000 mm, but will grow in areas of under 1,000 mm. Can tolerate short-term flooding.

Temperature. Tolerant of light frosts at higher altitudes and latitudes, but optimum temperatures are 30/25ºC during the growing season. Found at over 1,500 m asl on the island of Hawaii. Survived winter temperatures as low as -13°C in the Mississippi River Delta, Louisiana USA, and was the most vigorous of surviving warm-season legumes.

Light. Appears to have moderate shade tolerance; considered a weed in coffee plantations in South America.

Reproductive development. Flowers over a long growing period, October to April in Rio Grande do Sul, Brazil and in south-east Queensland, Australia. Behaves as a short day plant at higher latitudes.

Defoliation. Very tolerant of heavy grazing and frequently found with creeping grasses in heavily and continuously grazed swards.

Fire. Not usually burned because it occurs in locations which are heavily grazed. However, if burnt, it regrows from buds at the base of its woody stems, as well as regenerating from soil seed reserves.

Guidelines for the establishment and management of sown pastures.

Establishment. No longer sown commercially but was typically established in a fully prepared seedbed or broadcast into existing grasses. Recommended sowing rate of 5 kg/ha sown about 5 mm deep. Initial growth is slow, and trailing stems begin to develop some 6 months after sowing.

Fertiliser. Kaimi clover responds to P but is usually grown without fertiliser on moderately fertile soils. Responded to low levels of lime on a Hawaiian oxisol , but high levels (>6 t/ha) temporarily depressed growth.

Compatibility (with other species). Grows well with stoloniferous or rhizomatous grasses under heavy grazing. Companion species.

Grasses: Pennisetum clandestinum (higher altitudes in Hawaii), Brachiaria dictyoneura (humid tropical savannas in South America), B. mutica (Belize).

Pests and diseases. Reported to be sensitive to Peanut (Groundnut) Mottle Virus and may be a source of this to cultivated peanuts and soybeans in southern USA. Several fungal diseases reported, as are little leaf and Desmodium mosaic virus. Seedlings may be damaged by cutworms; rose beetles and cyst nematodes, Heterodera trifolii, have been reported in Hawaii. Light infestations by Meloidogyne spp. nematodes under coffee in Cuba.

Ability to spread. Spreads locally from creeping stems especially when pushed into moist soil. Seed pod segments stick to animal hair and human clothing (hence the name - beggar weed), while viable seed can be spread through cattle faeces.

Weed potential. Common on waste land and roadsides, and so is considered a weed in some circumstances. 

Feeding value

Nutritive value. Nitrogen concentrations of 2.0–2.5% have been reported. Palatability/acceptability High levels of tannins may reduce palatability .

Toxicity. No toxicity reported. 

Production potential

Dry matter. Yields of 6,500 kg/ha/year DM reported but yields are difficult to measure in such a low growing species when it is usually under heavy grazing. Under lenient grazing and additional fertiliser, D. incanum is often less productive than other species such as D. intortum , but is much more persistent and tolerant of grazing.

Animal production. No information available. 

Genetics/breeding. 2n = 22. Self-fertile but some outcrossing may occur. Hybrid of D. incanum x D. uncinatum is sterile.

Seed production. Long flowering period (October to April) in Rio Grande do Sul, Brazil. Best time for harvest was about 2,000 degree days.

Potential yields of over 700 kg/ha are greatly reduced by high rates of flower abortion, giving maximum estimated seed yield of 360 kg/ha. Commercial yields have been around 200 kg/ha.

Herbicide effects. Considered a weed in coffee plantations in South America but can be controlled with single application of either dalapon (8.0 kg/ha) or diquat (1.0 L/ha). Susceptible to trifluralin and fluchloralin
