Aeschynomene denticulata
Aeschynomene denticulata is a flowering plant in the legume family, Fabaceae, native to parts of South America. Kew records it from Bolivia, Brazil, northern Argentina, Paraguay and Uruguay. The species name was published by Velva Rudd in 1955.[1]
Appearance
Argentina's plant-health information service describes an erect plant about fifty to eighty centimetres tall. The stems bear yellowish bristles, particularly on young growth. Each leaf has numerous small, oblong leaflets whose toothed margins carry bristles.[2]
The flowers are yellow-orange with red lines on the broad upper petal. The fruit is a flattened pod divided into eight to fourteen roughly square segments, with bristles and wart-like swellings around the seed cavities.[2]
Regional records
The Argentine account records flowering and fruiting from January to May and elevations of one hundred and ninety to fourteen hundred metres. It also identifies the species as a weed of rice cultivation, where competition can reduce crop yield. These are regional observations, not evidence that it is invasive throughout its native range.[2]
Sources differ on its lifespan. Kew describes it as annual or biennial, while the Argentine botanical description calls it perennial.[1][2] Further study of the populations and treatments involved is needed to resolve that difference.
