Alysicarpus nummularifolius Contents |
Alysicarpus vaginalis is a species of flowering plant in the legume family, Fabaceae. It is native to parts of Africa and Asia, and it has been introduced to other continents, such as Australia and the Americas. [1] It is cultivated as a fodder for livestock, for erosion control, [2] and as a green manure. [3] Common names include alyce clover, buffalo clover, buffalo-bur, one-leaf clover, and white moneywort. [4]
This species is an annual or perennial herb; different varieties may be either annual or perennial, and some behave as perennials in wet conditions but grow as annuals in dry regions. [2] The stems take an erect form or run along the ground, [3] more often erect when growing in dense stands. [5] They reach one meter in length and usually have branches. [5] The leaves are not divided into leaflets. The blades are variable in shape and up to about 6.5 centimeters long. Racemes of up to 12 flowers occur at the stem tips and grow from the leaf axils. The flower corolla is half a centimeter long and can be shades of red, purple, blue, or yellow. The fruit is a lightly hairy, cylindrical but compressed legume pod up to 2.5 centimeters long. [3] The dark red seeds are no more than 1.5 millimeters long. [5]
This plant is grown in pastures as forage for livestock and is sometimes cut for hay. Cattle and horses find it palatable, and sheep found it about as palatable as alfalfa in one trial. It is very tolerant of grazing and mowing. [2]
It is most successful in the tropics, but it also grows well in warmer temperate regions. It loses leaves in light frosts and is killed by heavy frosts, but it grows back when winter ends. It tolerates shade and can be grown in the cover of shrubs. It grows in many types of soils, from sands to clays. It does not tolerate high soil salinity. [2]
The crop reportedly yields up to six tons of hay per hectare. If allowed to set seed it yields about 300 kilograms of seed per hectare. [2] To improve its nitrogen fixation for soil improvement the seeds can be inoculated with the rhizobia used for cowpeas. [6]
Good companion plants include grasses such as St. Augustine grass (Stenotaphrum secundatum), hurricane grass (Bothriochloa pertusa), and Nadi blue grass (Dichanthium caricosum). It can be grown with other legumes, such as Spanish clover (Desmodium heterophyllum) and showy pigeon pea (Cajanus scarabaeoides). [2]
A main disadvantage of the crop is its susceptibility to root-knot nematodes. Prevention measures include growing the plant on heavier soils, which reduce the severity of infestation, and to use certain cultivars that may be more resistant to nematodes. [2]
Other pests of the plant include leaf-mining caterpillars. [2] It is host to the plume moth Exelastis crepuscularis . [7] A number of seed beetles of the genus Bruchidius complete their larval development in the seeds of A. vaginalis, including two recently described from the plant. [8]
This species can become weedy. It has been a weed of golf courses, where it easily survives frequent mowing. [2] It is a weed of roadsides and other disturbed habitat in Guam, Hawaii, and Fiji. It is considered an invasive species on many Pacific Islands. [4]
Onobrychis viciifolia, also known as O. sativa or common sainfoin has been an important forage legume in temperate regions until the 1950s. During the Green Revolution it was replaced by high yielding alfalfa and clover species. Due to its anthelmintic properties the common sainfoin is a natural alternative to drugs to control nematode parasitism in the guts of small ruminants. This is the main reason why O. viciifolia came back to the scientific agenda during the last years.
Trifolium repens, the white clover, is a herbaceous perennial plant in the bean family Fabaceae. It is native to Europe, including the British Isles, and central Asia and is one of the most widely cultivated types of clover. It has been widely introduced worldwide as a forage crop, and is now also common in most grassy areas of North America, Australia and New Zealand. The species includes varieties often classed as small, intermediate and large, according to height, which reflects petiole length. The term 'white clover' is applied to the species in general, 'Dutch clover' is often applied to intermediate varieties, and 'ladino clover' is applied to large varieties.
Melilotus officinalis, known as sweet yellow clover, yellow melilot, ribbed melilot and common melilot, is a species of legume native to Eurasia and introduced in North America, Africa, and Australia.
Melilotus albus, known as honey clover, white melilot (UK), Bokhara clover (Australia), white sweetclover (USA), and sweet clover, is a nitrogen-fixing legume in the family Fabaceae. Melilotus albus is considered a valuable honey plant and source of nectar and is often grown for forage. Its characteristic sweet odor, intensified by drying, is derived from coumarin.
Cytisus proliferus, tagasaste or tree lucerne, is a small spreading evergreen tree that grows 3–4 m (10–13 ft) high. It is a well known fertilizer tree. It is a member of the Fabaceae (pea) family and is indigenous to the dry volcanic slopes of the Canary Islands, but it is now grown in Australia, New Zealand and many other parts of the world as a fodder crop.
Berteroa incana is a species of flowering plant in the mustard family, Brassicaceae. Its common names include hoary alyssum, false hoary madwort, hoary berteroa, and hoary alison. It is a biennial herb native to Eurasia and it has been introduced to western Europe and North America. It is listed as an invasive noxious weed in some areas of United States and Canada
Zornia latifolia is a species of flowering plant in the legume family, Fabaceae. It is native to South America. Its distribution may extend into Central and North America. It is also known as a naturalized species in tropical western Africa. The plant is known commonly as maconha brava.
Dalea purpurea is a species of flowering plant in the legume family known as purple prairie clover. Native to central north America, purple prairie clover is a relatively common member of the Great Plains and prairie ecosystems. It blooms in the summer with dense spikes of bright purple flowers that attract many species of insects.
Kummerowia stipulacea is a species of flowering plant in the legume family known by the common name Korean clover. It is native to China, Japan, Korea, and Russia, and it is present in the eastern United States as an introduced species.
Kummerowia striata is a species of flowering plant in the legume family known by the common names Japanese clover and common lespedeza. It is native to much of Asia and it is present in the eastern United States as an introduced species.
Psathyrostachys juncea is a species of grass known by the common name Russian wildrye. It was formerly classified as Elymus junceus. It is native to Russia and China, and has been introduced to other parts of the world, such as Canada and the United States. Psathyrostachys juncea is a great source of food for grazing animals, as it has high nutrition value in its dense basal leaves, even in the late summer and autumn seasons. This species can grow and prosper in many harsh environments, making it an ideal candidate for improvement as it can grow in areas were farming is difficult. This species is a drought-resistant forage plant and can survive during the cool seasons. It is also a cross-pollinator and is self-sterile. This means that P. juncea cannot self-fertilize; it must find another plant of the same species with which to exchange gametes. Self-sterilization increases the genetic diversity of a species.
Desmanthus virgatus is a species of flowering plant in the legume family that is known by many common names, including wild tantan, prostrate bundleflower, dwarf koa, desmanto, acacia courant, acacia savane, pompon blank, adormidera, brusca prieta, frijolillo, ground tamarind, guajillo, guashillo, huarangillo, langalet, petit acacia, petit cassie, petit mimosa, virgate mimosa, and slender mimosa, as well as simply desmanthus. It is native to the American tropics and subtropics but is present elsewhere as an introduced species. In some areas it is cultivated as a fodder and forage crop.
