Ribes quercetorum is a species of currant known by the common names rock gooseberry, oak gooseberry and oakwoods gooseberry. It is native to the mountains and hills of California from the San Francisco Bay Area south into Baja California and east into Arizona.Biota of North America Program 2014 county distribution mapSEINet, Southwestern Biodiversity, Arizona chapter photos, description, distribution mapCalflora taxon report, University of California, Ribes quercetorum E. Greene, Foothill gooseberry, oak gooseberry, rock gooseberry Ribes quercetorum grows in woodlands, chaparral, and dry desert slopes and canyons. It is a spreading shrub producing arching stems up to 1.5 meters (5 feet)long, the nodes along the stems bearing 1 to 3 spines each up to 1.5 centimeters (0.6 inch) long. The lightly hairy, glandular leaves are up to 3 centimeters (1.2 inches) long and are divided into a few lobes which are toothed or lobed at their tips. The inflorescence is a raceme of 2 or 3 small flowers. Each flower has five reflexed yellow sepals around a tube-shaped ring of smaller cream-colored petals. The fruit is an spherical, edible black berry just under a centimeter (0.4 inch) in diameter.Flora of North America, Ribes quercetorum Greene, 1885. Oak gooseberry

09Environmental DNA1 detections
Where the DNA of Ribes quercetorum 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.
