O jacarandá-paulista, jacarandá-do-mato, jacarandá-do-cerrado, jacarandá-pardo ou jacarandá-amarelo, é uma árvore nativa pertencente à família Fabaceae encontrada principalmente nos estados de Minas Gerais, Goiás e São Paulo. Essas árvores ocupam preferencialmente o Cerrado e a Caatinga, mas também são capazes de adentrar a Mata Atlântica. Atualmente encontra-se vulnerável devido à exploração madeireira e, principalmente, à perda de habitat para a agricultura e pecuária. "Jacarandá" provém do tupi iakarandá. Esta árvore pode fornecer madeira de lei muito semelhante à do jacarandá-da-bahia. Sua superfície é irregularmente lustrosa, com tronco pardo dotado de reflexos, listras ou sombras escuras. É muito utilizada na fabricação de mobília de luxo, objetos decorativos, tacos e assoalhos. Os jacarandás-paulista possuem inflorescências do tipo panícula, composta por flores brancas, com estandartes papilionados listrados de verde e branco, que apresentam um odor adocicado. Essa planta produz frutos do tipo sâmara, que normalmente são dispersados pelo vento. A floração costuma acontecer de agosto a janeiro, sendo mais intensa entre outubro e dezembro, enquanto a frutificação ocorre ao longo do ano, mas principalmente entre janeiro e junho. Flores e frutos podem ser encontrados nos meses de janeiro, março e outubro.

05DNA & barcoding2 specimens
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 Machaerium villosum has left across the world's sequence archives.

06Genome at a glanceCCDB
The complete instruction manualMachaerium villosum 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.

09Environmental DNA2 detections
Where the DNA of Machaerium villosum 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?
DNA read depthRead counts were not reported for this species — the map shows presence only, not how strong each trace was.
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.
