Aeschynomene americana is a species of flowering plant in the family Fabaceae (legume) known by many common names, including shyleaf,Aeschynomene americana. USDA Plants Profile. forage aeschynomene,Thro, A. M., et al. (1990). Weed potential of the forage legume Aeschynomene (Aeschynomene americana) in rice (Oryza sativa) and soybeans (Glycine max). Weed Technology 4(2) 284-90. American joint vetch (United States and Australia), thornless mimosa (Sri Lanka), bastard sensitive plant (Jamaica), pega pega, pega ropa, antejuela, ronte, cujicillo, and dormilonga (Latin America).Aeschynomene americana. FAO. It is native to Central America, parts of South America, the West Indies, and Florida. It is now found in the US, in Australia and in South-East Asia.Heuzé V., Thiollet H., Tran G., Salgado P., Lebas F., 2018. American jointvetch (Aeschynomene americana). Feedipedia, a programme by INRA, CIRAD, AFZ and FAO. https://www.feedipedia.org/node/569 Last updated on January 30, 2018, 14:16 This plant is an annual or perennial herb growing up to 2 meters tall. The leaves are up to 7 centimeters long and have several pairs of linear to oblong leaflets. The sensitive leaves fold up when touched. The inflorescence is a raceme of flowers each up to a centimeter long. The flowers range in color from white to pinkish, orange, or purplish. The fruit is a curved legume pod up to 4 centimeters long made up of several jointed units, each unit containing a seed. This species is widely used as a green manure or pasture plant throughout the tropical world.Zhang, J. (1998). Variation and allometry of seed weight in Aeschynomene americana. Annals of Botany 82 843-47. It is grazed by livestock and may be cut for hay.Aeschynomene americana. USDA NRCS Plant Fact Sheet. Cattle readily eat the plant and spread the seeds on their coats and in manure. Available cultivars include 'Glenn'. In the wild it is generally a wetland plant, easily taking hold in wet places such as drainage ditches. It is grazed by deers, and the seeds are eaten by wild birds.

A DNA barcode is a short, standardised stretch of genes that works like a fingerprint — enough to tell one species from another. Below is the molecular trace Aeschynomene americana has left across the world's sequence archives.
At a glance
★ the standard DNA barcode for this group — the short region actually read to tell this species apart. The rest are extra genes sequenced along the way.
The complete instruction manual Aeschynomene americana carries — its genome. We read it from three angles — how big it is, how the DNA is packed into chromosomes, and how completely it has been sequenced — and explain how to read each value as you go.
Chromosomes & ploidyhow the DNA is packaged
2n is the full chromosome count in a normal body cell; n is a gamete (egg or sperm), which carries half. Ploidy is how many complete chromosome sets each cell holds — 2× (diploid) is typical for animals, while higher levels (polyploidy) are common in plants.

How far back this lineage goes — and how we know. Everything here is measured in Ma, short for “mega-annum”: millions of years ago. The chart reads left to right like a calendar of the Earth, from the deep past on the left to today at the right edgetop to bottom like a core drilled through the Earth, from the deep past at the top down to today at the bottom.

When this lineage existed
How to read this: the coloured strip along the bottomdown the left is the geological calendar — the standard epochs (Pliocene, Pleistocene…) every museum uses, shown so you can see which chapter of Earth's history this lineage lived in. This lineage is a young one, so the strip is zoomed in to epochs — the finer subdivisions inside a period. The orange marker is the DNA clock: DNA accumulates mutations at a roughly steady rate, so comparing this species' DNA with its relatives estimates when the lineage split off — independently of any fossil.

Cultivated / Captivenot free-living
A living individual in a botanical garden, zoo or nursery — cultivated or kept, not free-living.
Where the DNA of Aeschynomene americana was picked up in samples of water, soil or air — nobody saw the organism, only its DNA left behind. A trace is a clue that the species was near, not a confirmed sighting.

How strong is each trace?
Modelled climatemodelled
How to read this: each dot is one detection of this species' DNA in an environmental sample. The confidence meter weighs how many independent studies and places back up the signal — one detection in one study is a hint; many across several studies is solid. Records dated before 2008 (when eDNA methods began) are treated as likely mislabeled and left off the map.
