Desmanthus virgatus

Scientific name

Desmanthus virgatus (L.) Willd.

Note: Turner (1950) regarded Desmanthus virgatus as an all-encompassing species, comprising D. virgatus , D. pubescens , D. pernambucanus, D. glandulosus and D. leptophyllus.  Despite taxonomic revision by Luckow (1993) resolving the complex to distinct species, identity within the complex is sometimes still confused, the most common example being with the widely sown D. pernambucanus.

No record


GRIN lists D. virgatus as being cultivated in Mauritius, India, and Hawaii, the same countries where D. pernambucanus is cultivated or naturalized.  It is probable this is another example of the confusion from the earlier taxonomic treatment of the D. virgatus complex.


Grazed by herbivores in the native range.  Component of improved permanent pastures in northern Australia. Can be used for hay, but requires rapid drying to avoid significant leaf drop.  Good levels of leaf retention have been achieved by cutting the crop with a mower-conditioner and not raking or turning the cut material prior to baling (see images).


While it is often claimed that D. virgatus is used in hedgerows in alley farming systems in India and Thailand, this is more likely a reference to its generally taller relative, D. pernambucanus.

Soil requirements

D. virgatus has been collected over a wide range of soil textures, from gravelly soils and sands, through loams to heavy clays, the main characteristic in common being that the soils are mainly neutral to alkaline in soil reaction.  Highest pH at collection sites in the Australian collection is pH 9, the lowest pH 5.5, and the mean pH 7.3.  At least some of the soils were saline.  The species has shown promise for use on neutral to alkaline cracking clay soils outside its native habitat, and may well have potential in areas with developing salinity.


Lowest average annual rainfall at collection sites was 230 mm, the highest 1600 mm, and the average 790 mm (SD 320 mm).  Well-adapted to 550‒1,000 mm average rainfall environments in exotic locations.  In low-rainfall (300‒400 mm/year), drought prone environments in northern Australia, D. virgatus was one of the very few species that persisted under grazing over a 14 year period.


Occurs over a wide temperature range from coastal to sub-montane environments and from the equator to 31° N in Texas, USA to 33° S in Río Negro Department, Uruguay, representing an average annual temperature range from about 17 °C to 27 °C, and including environments receiving regular frosts.  While lines tested are defoliated by heavy frosts, they regrow from crowns in spring given adequate moisture.


Poorly adapted to reduced light conditions, surviving but producing little dry matter under moderate shade, but dying out under more intense shade.

Reproductive development

Produces flowers and fruit year-round in the tropics, given sufficient soil moisture, and predominantly spring and early summer in the subtropics, although can be any time when moisture and temperature suitable.  In the monsoonal upland tropics, flowering and fruiting appear to be largely controlled by moisture and temperature.


Very tolerant of regular cutting and grazing by ruminants.


Regrows from the crown after moderate fire.  Fire can be useful in breaking seed dormancy, germination of  D. virgatus seed buried at 0.5‒3.0 cm and subjected to temperatures commonly occurring in grass fires increasing by up to 60%.  Grass fire temperatures kill seed located on the soil surface.


Guidelines for establishment and management of sown forages.


Sow 2 kg/ha of scarified seed at a depth of 0.5‒2.0 cm into moist soil with at least 50‒60 cm depth of good moist soil to ensure establishment.  Deeper planting depths may prevent or delay emergence.  Surface broadcasting onto a well-prepared seed-bed, followed by rolling; planting using a "crocodile" seeder; sod-seeding into slashed back pasture treated with glyphosate to suppress grass growth; or planting into cultivated strips; have also given satisfactory results.  Fresh seed is extremely hard-seeded and should be scarified, either abrasively (e.g. using a rice polisher) or by hot water treatment (4‒10 seconds in boiling water), to raise the germination to a minimum of 50‒70%.  While it is desirable to achieve good establishment from the initial sowing, it can be an advantage to sow a proportion of hard seed that can germinate with subsequent rainfall events in case of catastrophic loss of the initial stand.  Hard seed can remain dormant in the soil for 5 or 6 years.  Although Desmanthus spp. are not highly specific in their rhizobial demands and may nodulate effectively on native rhizobia, it may be advantageous to inoculate seed with a known effective strain of rhizobium such as CB 3126 recommended in Australia.  The presence of native Neptunia spp., a genus closely related to Desmanthus, may indicate presence of an effective rhizobial strain.  Recruitment from seed produced in grass-legume pastures does not occur until hardseededness has been overcome by weathering.  This may take some years since the half-life for breakdown of hard seed has been determined to be 60‒70 months under field conditions.


May respond to S, Mo, P, Cu and Mn on neutral to alkaline dark clay soils, particularly those formed on basalt.  Plants suffering from poor nodulation, sulfur deficiency and molybdenum deficiency all exhibit poor growth and yellowing of the leaves (chlorosis). Use of an effective strain of rhizobium (e.g. CB 3126) ensures good nodulation.  Sulfur deficiency is not always diagnosable from soil test, but tissue analysis may assist.  A critical leaf tissue concentration of 0.2% S is required for optimum productivity.  In the absence of tissue test, application of sulfate (gypsum, superphosphate) to deliver 20 kg S/ha in a test strip should  indicate adequacy or deficiency.  Molybdenum at 100 g/ha as sodium molybdate (soluble, 300 g/ha) or molybdenum trioxide (insoluble, 150 g/ha) is usually sufficient to overcome Mo deficiency.  Phosphorus should be applied as indicated by soil test, or at 20‒30 kg/ha.

Compatibility (with other species)

In northern Australia, cv. Marc has persisted and increased in buffel grass (Cenchrus ciliaris) pastures and in pastures dominated by Queensland bluegrass (Dichanthium sericeum).  Recruitment from high soil seed levels is irregular but successful in favourable seasons.

Companion species

Grasses:  Cenchrus ciliaris, Dichanthium sericeum, Panicum coloratum var. makarikariense

Legumes: Clitoria ternatea, other Desmanthus spp., Medicago sativa

Pests and diseases

Occasional, minor damage by psyllid insects (Acizzia spp.) was reported in northern Australia.  The psyllids cause more serious damage in seed crops.  Several seed-eating bruchid beetles (5 Acanthoscelides spp. and 1 Stator sp.) are known to infest Desmanthus.  Recorded as a host for alfalfa mosaic virus.

Ability to spread

Being early flowering and producing large seed crops, D. virgatus has the potential to spread under grazing given reasonable rainfall conditions.

Weed potential

Has potential to become a minor weed of disturbed areas.  Its low growth habit limits its ability to dominate companion species.

Feeding value
Nutritive value

Nutritive value of the various species of Desmanthus evaluated have been largely similar based on laboratory testing.  Crude protein concentration of the entire plant ranges from 10.5 to 15.5%, with leaves averaging 22.4% and stems 7.1%.  A study of 18 accessions grown in India reported an average CP of 21% (range 15‒27%), and average NDF and ADF concentrations of 42 and 35%, respectively.  In sacco DMD and N concentration of CPI 78382 were 65% and 3.5%, respectively.


Palatable to grazing ruminants and grazed by beef cattle throughout the growing seasonDesmanthus has been observed to be less palatable than leucaena (Leucaena leucocephala) but more readily eaten than Stylosanthes scabra cv. Seca.


No toxicities to ruminant livestock were reported in the literature.  Desmanthus spp. do not cause bloat in ruminants because they contain 2‒3% (of total DM as tannic acid equivalent) condensed tannins.

Production potential
Dry matter

The relative contribution of D. virgatus to pasture yield increases with the severity of the environment, so that it has the potential to be more valuable on soils of at least moderate fertility in sub-humid, seasonally dry environments.  In more testing environments, its relative contribution to pasture yield can be significant, whereas in highly favourable environments, other legume species may make a greater contribution to yield.  While D. virgatus has produced 7.6 t/ha DM in the humid tropics and 7.1 t/ha DM under irrigation in a sub-humid environment, yields of 2.0‒2.4 t/ha/year DM in rain-fed, 600‒750 mm rainfall environments are more common.  Presentation yields of D. virgatus CPI 78382 and cv. Marc in grazed pastures in Australia ranged from 100 to 600 kg/ha DM over 6 below-average rainfall years and contributed between 3 and 20% of total DM yield.

Animal production

In a pen feeding experiment where a Mitchell grass (Astrebla spp.) basal diet was supplemented with D. virgatus accessions CPI 78382 and CPI 79653, DM intake of Merino wethers increased from 580 to 752 and 753 g/head/day, respectively, and wool growth increased from 0.48 to 0.69 and 0.73 g/day/cm², respectively.  Inclusion of Desmanthus spp. in mixed grass legume pastures has been shown to improve liveweight gain in cattle. Steers on a mixed buffel grass (Cenchrus ciliaris) - Desmanthus pasture gained 40 kg/head over the 90 day cool/dry season, while those on buffel grass alone had a net gain of 10 kg/head.


Taxonomic confusion within the genus has led to D. pernambucanus, D. leptophyllus, D. pubescens and D. virgatus all being evaluated as D. virgatus.  However, there is considerable genetic and morphological diversity within D. virgatus that may have potential for cultivar development.  Genotypes from the northern Caribbean are very different from  provenances from Mexico, which in turn are different from those in Argentina.  D. virgatus germplasm has been evaluated for agronomic potential in India, southern USA and northern Australia. Considerable intraspecific hybridization has been observed in nursery plots where a number of accessions are grown in fairly close proximity. Persistent types have been selected from discontinued evaluation sites.  Current work looking at interspecific hybrids between D. virgatus and D. leptophyllus and D. bicornutus is producing promising results.  Chromosome number 2n = 28.

Seed production

D. virgatus accessions have proven to be prolific, early seed producers.  Seed yields of 400‒500 kg/ha are achieved from direct-headed crops, despite considerable seed losses occur due to uneven ripening and early seed fall.  The potential seed yield using a suction harvester is in excess of 1,000 kg/ha, although the suction required to collect the small, dense Desmanthus seed can result in large quantities of small stones in the sample. A native psyllid insect (Acizzia spp. Hemiptera: Psyllidae) can cause severe damage to seed crops in Australia and may need to be controlled using insecticides such as dimethoate.

Herbicide effects

D. virgatus seedlings are susceptible to the various hormone type herbicides such as 2,4-D, 2,4-DB, dicamba, MCPA and MCPB.  The main role of herbicides with this species is in seed production.  The pre-emergent herbicides, imazaquin, imazethapyr, pendimethalin, oryzalin and trifluralin, can give useful weed control with very little crop damage, provided they are used according to recommendation.  Grass weeds can be controlled with the post-emergent herbicides, haloxyfop, clethodim, propyzamide, carbetamide and dalapon, and broad-leaved weeds with the selective post-emergence herbicides, bentazone, bromoxynil and imazethapyr.  Atrazine, terbacil and hexazinone have shown some potential in controlling mature perennial weeds in second-year desmanthus seed crops showed.
