Lithophragma parviflorum is a species of flowering plant in the saxifrage family known by the common name smallflower woodland star. It is native to much of western North America from British Columbia to California to South Dakota and Nebraska, where it grows in several types of open habitat. It is a rhizomatous perennial herb growing erect or leaning with a naked flowering stem. The leaves are mainly located low on the stem, each cut into three lobes or divided into three lobed leaflets. The stem bears up to 14 flowers, each in a cuplike calyx of red or green sepals. The five petals are bright white, up to 1.6 centimeters long, and usually divided into three toothlike lobes. Its bulblets may produce toxins capable of poisoning livestock, although rodents eat them with no known adverse effects.

The complete instruction manualLithophragma parviflorum 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.

Where the DNA of Lithophragma parviflorum 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.
