Ribes amarum is a species of currant known by the common name bitter gooseberry.[2] It is endemic to California , where it is known from mountains, foothills, and canyons. Its habitat includes Chaparral.[6]

Description

Ribes amarum is a shrub growing to one to two meters (40-80 inches) in height. Nodes along the stem each bear three spines up to a centimeter (0.4 inch) in length. The hairy, glandular leaves are 2 to 4 centimeters (0.8-1.6 inches) long and generally rounded in shape, divided into 3 to 5 rounded toothed lobes.[7]

The inflorescence is a solitary flower or raceme of up to three flowers which hang from leaf axils. The showy flower has five pointed sepals in shades of purple-red which are reflexed upward. At the center is a tubular corolla of white or pink-tinged petals around five stamens and two styles. The fruit is a bristly berry up to 2 centimeters wide which is bright red, ripening purple.[7]
