Geum rossii is a species of flowering plant in the rose family known by the common names Ross' avens and alpine avens. It is native to North America where its distribution spans northern Canada and the high mountains of the western United States. It grows at high-latitude and high-elevation habitat, including the Arctic and in alpine climates. There are three varieties. One, var. depressum, is endemic to Washington in the United States, where it is limited to the Wenatchee Mountains.Geum rossii var. depressum. USFS Celebrating Wildflowers Critically Imperiled Plant Profile. The plants' flowers are similar in appearance to those of species in the Potentilla (or cinquefoil) genus. Geum rossii has less flowers per stem and leaves which are somewhat fernlike.

06Genome at a glanceCCDB
The complete instruction manualGeum rossii 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.

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.
