Question: Do Waldsteinia and Obregonia contain the same number of species?

full_context: Document 1: Waldsteinia: Waldsteinia, the barren strawberries, is a genus of the rose family (Rosaceae). It contains about six species native to the temperate Northern Hemisphere. A number of species are cultivated as a ground cover in gardens, including "Waldsteinia fragarioides" from North America, "Waldsteinia geoides" from Europe, "Waldsteinia lobata", and "Waldsteinia ternata" from Eurasia (from Central Europe to Siberia, China, and Japan).
Document 2: Cotoneaster dammeri: Cotoneaster dammeri, the bearberry cotoneaster, is a species of flowering plant in the genus "Cotoneaster", belonging to the Rosaceae family, native to central and southern China (Gansu, Guizhou, Hubei, Sichuan, Tibet and Yunnan) and naturalized in Europe.
Document 3: Opuntia atrispina: Opuntia atrispina is a cactus species in the "Opuntia" genus. It has limited distribution in the United States. In Texas it can be found from near Uvalde to Del Rio/Langtry--a small strip of area just 50 miles long.
Document 4: Opuntia aciculata: Opuntia aciculata, also called Chenille pricklypear, old man's whiskers, and cowboy’s red whiskers, is a perennial dicot and an attractive ornamental cactus native to Texas. It belongs to the genus "Opuntia" prickly pear cacti. It is also widespread in Nuevo Leon, Tamaulipas (northern Mexico).
Document 5: Arctostaphylos rubra: Arctostaphylos rubra is a species of flowering plant in the heath family and the genus "Arctostaphylos", the manzanitas and bearberries. Common names include red fruit bearberry, alpine bearberry, arctic bearberry, red manzanita, and ravenberry. It is native to Eurasia and northern North America from Alaska through most of Canada to Greenland. There is also one population in the contiguous United States, located in the Absaroka Mountains of Wyoming.
Document 6: Bearberry: Bearberries are three species of dwarf shrubs in the genus "Arctostaphylos". Unlike the other species of "Arctostaphylos" (see manzanita), they are adapted to Arctic and Subarctic climates, and have a circumpolar distribution in northern North America, Asia and Europe, one with a small highly disjunctive population in Central America.
Document 7: Fragaria: Fragaria is a genus of flowering plants in the rose family, Rosaceae, commonly known as strawberries for their edible fruits. There are more than 20 described species and many hybrids and cultivars. The most common strawberries grown commercially are cultivars of the garden strawberry, a hybrid known as "Fragaria" × "ananassa". Strawberries have a taste that varies by cultivar, and ranges from quite sweet to rather tart. Strawberries are an important commercial fruit crop, widely grown in all temperate regions of the world.
Document 8: Escobaria: Escobaria, pincushion cactus or foxtail cactus is a genus of low-growing cacti that range from the southernmost parts of central and western Canada through northern Mexico, with one species in Cuba. The genus comprises about 23 species. The term "pincushion cactus" may also refer to the related "Mammillaria".
Document 9: Escobaria sneedii: Escobaria sneedii (syn. "Coryphantha sneedii") is a rare species of cactus known by the common names Sneed's pincushion cactus and carpet foxtail cactus. It is native to the Chihuahuan Desert, where it occurs in scattered locations in New Mexico, Texas, and Chihuahua. Some plants occurring in Arizona may be included within this species. Botanical authors do not necessarily agree on the circumscription of this species. Most will agree at this point in the research, however, that there are two varieties of "Escobaria sneedii", and that both are rare and endangered. The plant is popular with cactus enthusiasts and dealers because of its often petite size and tolerance for moderately cold climates. They have been overharvested from their natural habitat, the main reason why the two varieties, var. "sneedii" and var. "leei", have been federally listed as endangered and threatened, respectively.
Document 10: Fragaria × vescana: Fragaria × vescana is a hybrid strawberry cultivar that was created in an effort to combine the best traits of the garden strawberry ("Fragaria" × "ananassa"), which has large berries and vigorous plants, with the woodland strawberry ("Fragaria vesca"), which has an exquisite flavour, but small berries.
Document 11: Obregonia: Obregonia, the artichoke cactus, is a genus of cacti with a single species, Obregonia denegrii. The species is endemic to the state of Tamaulipas in Mexico.
Document 12: Fragaria × bringhurstii: Fragaria" × "bringhurstii is a naturally occurring hybrid species of strawberry native to the West Coast of the United States. The species results from the natural intercrossing of "Fragaria vesca" and "Fragaria chiloensis", native species whose ranges overlap in that region.
Document 13: 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. Some thickets may be 20- to 40-ft across and composed of multiple plants. The fruit is purplish. The cladodes are uniquely shaped, obovate with a neck. The original description claimed the plants were yellowish green, but they may be green or rarely blue-green.
Document 14: Schlumbergera opuntioides: Schlumbergera opuntioides is a species of plant in the Cactaceae family. It is endemic to the coastal mountains of south-eastern Brazil where its natural habitats are humid forests and rocky areas. It is threatened by habitat loss. It is in the same genus as the popular house plant known as Christmas Cactus or Thanksgiving Cactus.
Document 15: 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".
