Richardia brasiliensis is a species of flowering plant in the coffee family known by the English common names tropical Mexican clover,Richardia brasiliensis. USDA Plants Profile. Brazilian calla-lily, white-eye, and Brazil pusley.Richardia brasiliensis. University of Florida IFAS Extension. In Brazil it is known as poaia branca.Pinto, D. S., et al. (2008). Secondary metabolites isolated from Richardia brasiliensis Gomes (Rubiaceae). Revista Brasileira de Farmacognosia 18(3) 367-72. It is native to South America. It is an introduced species and sometimes an invasive weed in many other places, including Hawaii, Indonesia, Japan, and Thailand.Richardia brasiliensis. Pacific Island Ecosystems at Risk. It is a weed of citrus groves in Florida.Chandran, R. S. and M. Singh. (2003). Survey and control of Brazil pusley (Richardia brasiliensis) in Florida citrus. Proc Fla State Hort Soc 116 211-14. This plant may be an annual or perennial which grows from a deep root. The branching stems grow up to 40 centimeters long and lie prostrate or grow upright. The oppositely arranged leaves are oval with pointed or rounded tips. They are up to 6.5 centimeters long. The inflorescence is a cluster of up to 20 flowers, or sometimes more. The petals are white or rose-pink. The fruit is a hairy nutlet. The root is often a home to nematodes. In Brazil this plant is used medicinally as an antiemetic and for diabetes.

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 Richardia brasiliensis 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 Richardia brasiliensis 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.

Where the DNA of Richardia brasiliensis 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 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.
