More about this plant
Avenula is a genus of Eurasian flowering plants in the grass family. Over 100 names have been proposed for species, subspecies, varieties, and other infraspecific taxa within Avenula, but only one species is accepted. The others names are all regarded as synonyms of other accepted names. The only recognized species in the genus is Avenula pubescens, commonly known as downy oat-grass or downy alpine oatgrass, native to Europe and Asia from Iceland and Portugal to Xinjiang, Mongolia, and Siberia. It is also naturalized in scattered locations in North America, in states as Connecticut, Delaware, Minnesota, New Jersey and Vermont, and in Canadian provinces such as Alberta, Manitoba, Ontario, Quebec, and Saskatchewan.

How we know this (1) Methods & honest limits
A recorded categorical fact: each species is tagged C3 (standard), C4 (heat/water-efficient) or CAM (succulent, night-time CO₂ uptake) — or a facultative combination. We only show a trait card for the noteworthy C4/CAM cases; C3 is the unremarkable majority, kept in the data but not surfaced as a card.
