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

Context paragraphs:
Malvaceae: Malvaceae, or the mallows, is a family of flowering plants estimated to contain 244 genera with 4225 known species.  Well-known members of this family include okra, cotton, cacao and durian.  The largest genera in terms of number of species include "Hibiscus" (300 species), "Sterculia" (250 species), "Dombeya" (250 species), "Pavonia" (200 species) and "Sida" (200 species).

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).

Stapeliae: The genera of plants within the tribe Stapeliae are all to varying degrees stem succulents.  Many of the species resemble cacti, though are not closely related, as an example of convergent evolution.  The stems are often angular, mostly four-angled in cross-section, but in some species there are six or more, with some species of "Hoodia" having more than thirty angles.  In size they vary from less than 2.5 cm/1" in length to over 2 m/6" tall.  The leaves are in most species reduced to rudiments, sometimes hardened and thorn-like, arranged on bumps or tubercles on the angles.  Some species, however, still have recognisable leaves, most notably the Indian species "Frerea indica", and some members of "Tridentea".  Stapeliads are most abundant in warm, dry climates.  In Africa, there are two separate regions where Stapeliads have most diversified: northeast Africa, and Southern Africa.  Several species are endemic to the small island of Socotra off the Horn of Africa.  The Arabian Peninsula, and most specifically the country of Yemen, contain another concentration of species.  Several more are found in the drier parts of Pakistan, Afghanistan, India, Nepal, and Myanmar.  A single species, "Caralluma europea" is found in Europe, in the very southern part of the Iberian peninsula.  Stapeliads are often regarded as a climax group within the family because of their often structurally complex flowers. Certain aspects of these reproductive parts mirror the pollination systems in the Orchid family and represent a case of parallel evolution though both groups are quite unrelated and have developed similar, though not identical means to achieve the ultimate goal of pollination and therefore reproduction.  Most stapeliads use flies as pollinators, that are attracted to odours resembling dung or rotting meat, emanating from the flowers.  Many of the flowers also bear some physical resemblance to rotting animal carcasses, leading to their popular name of Carrion Flowers.  However, not all stapeliads smell bad, or attract flies.  Some species use beetles, bees, wasps, butterflies or moths as pollinators.  Stapeliad flowers range in size from mere millimetres in species of "Echidnopsis" and "Pseudolithos" to those of "Stapelia gigantea" that can reach 40 cm/16" in diameter, and are some the largest of flowers to be found on any species of succulent.

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.

Balkan temperate rainforests: Balkan temperate rainforests are a small portion of the southeastern Alps and Balkan region contain relatively low elevation (< 1600 m ASL) temperate rainforest flora and fauna.  Annual rainfall is in excess of 1600 mm, supporting a variety of lichens, tree species, and animal species.  These forests, comprising approximately 580,000 hectares, contain a variety of remnant plant and animal species associated with rainforest ecosystems and not found throughout the larger ecoregion recognized by the WWF, the Balkan mixed forest type.

Cichorieae: The Cichorieae (also called Lactuceae) are a tribe in the plant family Asteraceae that includes 93 genera and more than 1600 sexually reproductive species and more than 7000 apomictic species.  They are found primarily in temperate regions of the Eastern Hemisphere.  Cichorieae all have milky latex and flowerheads that only contain one type of floret.  The genera "Gundelia" and "Warionia" only have disk florets, while all other genera only have ligulate florets.  The genera that contain most species are "Taraxacum" (Crepidinae subtribe) with about 1600 apomictic species, "Hieracium" with about 770 sexually reproducing and 5200 apomictic species, and "Pilosella" with 110 sexually reproducing and 700 apomictic species (both Hieraciinae).  Well known members include lettuce, chicory, dandelion, and salsify.

Xylothamia: Xylothamia, the desert goldenrods, is a genus of flowering plants in the daisy family, Asteraceae.  Until 2003, it was held to contain nine species of shrubs native to deserts of Mexico and the southwestern United States.  However, it seems to contain at least two groups.  Four species are related to "Gundlachia" and may be moved to that genus.  The relationships of the other five species is not quite as clear.  All nine species do belong in the subtribe Solidagininae.

Species–area curve: A species–area curve describes the relationship between the area of a habitat, or of part of a habitat, and the number of species found within that area.  Larger areas tend to contain larger numbers of species, and empirically, the relative numbers seem to follow systematic mathematical relationships.  The species–area relationship is usually constructed for a single type of organism, such as all vascular plants or all species of a specific trophic level within a particular site.  It is rarely, if ever, constructed for all types of organisms if simply because of the prodigious data requirements.  It is related but not identical to the species discovery curve.

List of Indonesian endemic freshwater fishes: This page contain the list of Indonesian endemic freshwater fishes.  Indonesia is a country with vast amount of freshwater fish species.  Indonesia has the 3rd rank of the country with the largest number of freshwater fish species in the world, with the total of 1155 species.  And about 440 species are Indonesian endemic.  This makes Indonesia as the 4th country with the largest endemic freshwater fish species, with Brazil (1716 species) in the 1st place, China (888) in the 2nd place and USA (593 species) in the 3rd place.

Bivalvulida: The Bivalvulida is an order of myxosporean parasites which contains a number of species which cause economically significant losses to aquaculture and fisheries, such as "Myxobolus cerebralis" and "Ceratomyxa shasta".  The Myxosporean stages of members of the bivalvulida are characterised by their two spore valves (hence the name), which meet in a "suture line" which encircles the spore.  They usually contain 2 polar capsules, but species have been reported which contain either 1 or 4.
