Anisocoma acaulis (scale bud) is a wildflower found in the Mojave, Colorado Deserts, and California's Owens Valley above 2000 ft (states of Arizona, Nevada, California, Baja California, and Sonora), up to about 7000 ft.Biota of North America Program, 2013 county distributioni mapCONABIO. 2009. Catálogo taxonómico de especies de México. 1. In Capital Nat. México. CONABIO, México D.F.. It is the only known member of genus Anisocoma.Torrey, John & Asa Gray. 1845. Boston Journal of Natural History 5(1): 111 description in Latin, commentary in EnglishTorrey, John & Asa Gray. 1845. Boston Journal of Natural History 5(1): plate XIII, figures 7–11 line drawings as illustrations The plant grows a flat mat of jagged lobed leaves that lie on the ground. It sends up stalks up to 20 centimeters tall topped with flowers which bloom from April to June. The flowers may be yellow or white with yellow centers. The frilly ray florets are rectangular with flat or slightly toothed tips. This flower is found growing in colonies in sandy places and washes, and bleeds milky sap if cut. The common name "scale bud" is a reference to the scaly appearance of the closed flower bud.Flora of North America Anisocoma acaulis Torrey & A.

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 Anisocoma acaulis has left across the world's sequence archives.

06Genome at a glanceCCDB
The complete instruction manualAnisocoma acaulis 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 Anisocoma acaulis 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.
