Calea zacatechichi est une espèce de plante à fleurs de la famille des Asteraceae aussi connue sous le nom de herbe rêveuse ou Dream herb. Le nom de l'espèce, zacatechichi, vient du nahuatl et signifie herbe amère. La Calea est une plante utilisée par les indigènes Chontal de l'état mexicain d'Oaxaca pour soigner la fièvre et la toux. Elle pousse naturellement du Sud du Mexique au Nord du Costa Rica. Il a été scientifiquement démontré que des extraits de cette plante augmentent le temps de réaction et la fréquence et/ou le souvenir des rêves et celui sans ré-apparition de symptômes fievreux contre des placebos et du diazepam. Elle était aussi employée par le peuple Chontal comme une herbe médicinale contre les troubles gastriques et intestinaux, stimulateur d'appétit, remède anti-dysenterie, et comme un agent anti-fièvre.

05DNA & barcoding1 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 Calea ternifolia has left across the world's sequence archives.

06Genome at a glanceGoaT
The complete instruction manualCalea ternifolia 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. Click any value below to see the underlying records and sources.

09Environmental DNA1 detections
Where the DNA of Calea ternifolia 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.
