full_context: Document 1: Copiapoa atacamensis: 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 .
Document 2: Rubieae: Rubieae is a tribe of flowering plants in the Rubiaceae family and contains 969 species in 14 genera. The genus "Galium" is responsible for more than two thirds of the species in the tribe. The second largest genus is "Asperula", which contains about 200 species. Unlike the rest of the Rubiaceae family, the tribe contains predominantly perennial and annual herbs with pseudowhorls of leaves and leaflike stipules and is centered in temperate and tropical-mountain regions.
Document 3: Gooseberry: 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).
Document 4: Rheum ribes: 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.
Document 5: Opuntia anahuacensis: Opuntia anahuacensis is a cactus species in the "Opuntia" genus and a member of the Opunitioideae. It grows along the Gulf Coast of Texas, and perhaps northern Mexico. The plants are short, perhaps 1- or 2-ft tall, but they are wide.

The original description claimed the plants were yellowish green, but they may be green or rarely blue-green.
Document 6: Puya coquimbensis: Puya coquimbensis is a species in the Bromeliaceae family. This species is a rare plant found in certain portions of Chile including Punta Teatinos and Cerro La Campana. In La Campana National Park "P.coquimbensis" is associated with the endangered Chilean Wine Palm, "Jubaea chilensis", which palm prehistorically had a much wider distribution.
Document 7: Ribes: 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".
Document 8: Copiapoa cinerea: 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.
Document 9: Jostaberry: 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".
Document 10: Schlumbergera: Schlumbergera is a small genus of cacti with six species found in the coastal mountains of south-eastern Brazil. Plants grow on trees or rocks in habitats that are generally shady with high humidity, and can be quite different in appearance from their desert-dwelling cousins. Most species of "Schlumbergera" have stems which resemble leaf-like pads joined one to the other and flowers which appear from areoles at the joints and tips of the stems. Two species have cylindrical stems more similar to other cacti. In Brazil, the genus is referred to as "Flor de Maio " (May flower), reflecting the period in which they flower in the Southern Hemisphere.
Document 11: Rubus: Rubus is a large and diverse genus of flowering plants in the rose family, Rosaceae, subfamily Rosoideae, with 250–700 species.
Document 12: Echinopsis: Echinopsis is a large genus of cacti native to South America, sometimes known as hedgehog cactus, sea-urchin cactus or Easter lily cactus. One small species, "E. chamaecereus", is known as the peanut cactus. The 128 species range from large and treelike types to small globose cacti. The name derives from "echinos" hedgehog or sea urchin, and "opsis" appearance, a reference to these plants' dense coverings of spines.
Document 13: Copiapoa: 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.
Document 14: Fouquieria: Fouquieria is a genus of 11 species of desert plants, the sole genus in the family Fouquieriaceae. The genus includes the ocotillo ("F. splendens") and the boojum tree or cirio ("F. columnaris"). They have semisucculent stems with thinner spikes projecting from them, with leaves on the bases spikes. They are unrelated to cacti and do not look much like them; their stems are proportionately thinner than cactus stems and their leaves are larger.
Document 15: Ribes glandulosum: Ribes glandulosum, the skunk currant, is a North American species of flowering plant in the currant family. It is widespread in Canada (all 10 provinces and all 3 territories) and is also found in parts of the United States (Alaska, the Great Lakes region, the Appalachian Mountains, and the Northeast).
