Question: Which has more species, Ribes or Copiapoa?
Context: The jostaberry is a complex-cross fruit bush in the "Ribes" genus, involving three original species, the black currant "R. nigrum", the North American coastal black gooseberry "R. divaricatum", and the European gooseberry "R. uva-crispa".  It is similar to "Ribes × culverwellii", the Jochelbeere, which is descended from just two of these species, "R. nigrum" and "R. uva-crispa". Rheum ribes, the Syrian rhubarb or currant-fruited rhubarb, rhubarb-currant, warted-leaved rhubarb, warty-leaved rhubarb, rhubarb of Babilonia is an edible wild rhubarb species in the genus "Rheum".  It grows between 1000 and 4000 m on dunite rocks, among stones and slopes, and is distributed in the temperate and subtropical regions of the world, chiefly in Western Asia (Turkey, Syria, Lebanon, Iraq, Iran, Azerbaijan, Armenia) to Afghanistan and Pakistan.  The Syrian rhubarb a partially commercial vegetable collected from the nature in Eastern and Southern Anatolia, Northern Iraq and partly Northwestern Iran in early spring.  "Rheum ribes" is considered as a valuable medicinal species in herbal medicine. Ribes colandina is a species of currant found only in Perú.  "Ribes colandina" differs from "Ribes andicola" in uniformly dark red flowers (petals red, not orange-yellow as in "R. andicola"), black instead of yellow fruits and wider, more deeply lobed leaves. Ribes sanchezii is a species of currant, named after Peruvian botanist Isidoro Sánchez Vega of Cajamarca.  This species of "Ribes" is distinct form both "R. andicola" and "R. colandina" because of its ovate to elliptical leaves with a very poorly developed lateral lobe and its aberrant indument.  The two latter species have leaves with pubescence on both the adaxial and abaxial surface and the adaxial leaf surface is matt green, whereas "R. sanchezii" has a shiny dark green upper leaf surface and pubescence abaxially restricted to the primary and secondary veins.  "Ribes sanchezii" also has strongly resupinate fruits, whereas the fruits of "R. andicola" and "R. colandina" are pendulous. Ribes is a genus of about 150 known species of flowering plants native throughout the temperate regions of the Northern Hemisphere.  It is usually treated as the only genus in the family Grossulariaceae, but a few taxonomists place the gooseberry species in a separate genus of "Grossularia". Copiapoa cinerea is a species of the genus "Copiapoa" in the family of Cactaceae.  The epithet "cinerea" comes from the Latin word for ash, by reference to the colour of the epidermis. The gooseberry ( or (American and northern British) or (southern British)), with scientific names Ribes uva-crispa (and syn.  Ribes grossularia), is a species of "Ribes" (which also includes the currants). Copiapoa atacamensis is a species of cactus from the Atacama Desert in the province of Antofagasta in northern Chile.  Its relationship with other species of "Copiapoa", such as "C. calderana", are unclear as of April 2012 . Ribes aureum, known by the common names golden currant, clove currant, pruterberry and buffalo currant, is a species in the genus "Ribes".  It is native to Canada, most of the United States (except the southeast) and northern Mexico.  The variety "Ribes aureum" var.  "villosum" is sometimes considered a full species, Copiapoa is a genus of cacti from the dry coastal deserts, particularly the Atacama Desert, of northern Chile.  It comprises about 26 species.  These species vary in form from spherical to slightly columnar and in color from a brownish to blue-green body.
