Uebelmanniinae
''Uebelmannia'' is genus of cacti, native to southeast Brazil. In a 2023 classification of the tribe Cereeae, it was placed as the only genus in the subtribe Uebelmanniinae, having formerly been placed in the subtribe Rebutiinae. Description Plants in the genus ''Uebelmannia'', individual plants grow without branching and form spherical to cylindrical shoots that can reach heights of up to . The plant's surface can be smooth, papillate, granular, or covered with waxy deposits. Most plants have sharp-edged ribs, although some may have ribs that are divided into bumps. Each plant has two to seven spines that emerge from the areoles, which are arranged in a protruding, spreading, or comb-like pattern. These spines can be straight or slightly curved. The small, short, funnel-shaped flowers of ''Uebelmannia'' are yellow and typically bloom near the tip of the shoot during the day. The flower tubes are covered with a few areoles, from which dense wool and a few bristles emerge. The fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cereeae
Cereeae is a tribe of cacti belonging to the subfamily Cactoideae containing about 50 genera, divided in 2023 among six subtribes. Description Cereeae are tree-like or shrubby, sometimes climbing plants. Their mostly elongated to spherical, ribbed and thorny shoots are not articulated. The flowers, which usually appear on the side of the shoot, open during the day or at night. Their pericarpels usually have a few scales or are completely glabrous. The fleshy, berry-like, bursting or non-bursting fruits often have a blackening adherent flower remnant. The small to large seeds are oval. The hilum and micropyle of the seeds are fused, one appendage is absent. Taxonomy Phylogeny In classifications before the use of molecular phylogenetic methods, Cereeae was one of nine tribes into which the subfamily Cactoideae was divided. Molecular studies found that these traditional tribes were not monophyletic. A broader circumscription of Cereeae, including Browningieae and Trichocereeae and ...

Rebutiinae
The Rebutiinae are a subtribe of cactus, cacti belonging to the subfamily Cactoideae, tribe Cereeae. A 2010 classification accepted seven or eight genera, but when Circumscription (taxonomy), circumscribed in this way, the subtribe was not Monophyly, monophyletic. A 2023 classification reduced Rebutiinae to three genera. Description Rebutiinae are large tree-like or shrubby plants. Their columnar shoots are articulated or not articulated. The ribs are usually heavily spined. The medium to large flowers appearing on the side usually open at night. Their pericarpel has imbricated scales. The areoles have thorns or bristles. The fleshy fruits are not bursting, scaly, thorned or glabrous. The medium-sized to large seeds are often wrinkled. The hilum and micropyle of the seeds are fused, an appendage is absent, and a mucous sheath is sometimes present. Taxonomy In a 2010 classification of the tribe Cereeae, the subtribe Rebutiinae comprised seven or eight genera, depending on whether ...

''Uebelmannia pectinifera'' is a species of plant in the family Cactaceae. It is Endemism, endemic to Brazil. Its natural habitats are dry savanna and rocky areas. It is threatened by habitat loss. Description ''Uebelmannia pectinifer'' is a solitary and globular species, becoming columnar with age, grows with dark reddish-brown to grayish, more or less cylindrical bodies that reach heights of growth of up to 100 centimeters and a diameter of up to 15 centimeters. The epidermis usually appears granular and is covered with waxy white scales. The 15 to 40 ribs are sharp-edged. The brownish to gray felty areoles on it are very close together. The 1 to 4 brown to almost black spines are protruding, often intertwine and then form a "comb". They are up to 2 centimeters long. The slender, funnel-shaped, light yellow flowers that bloom diurnal in the summer, up to 1.5 centimeters long and reach a diameter of 1 centimeter.

Species
A species () is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Cactus
A cactus (: cacti, cactuses, or less commonly, cactus) is a member of the plant family Cactaceae (), a family of the order Caryophyllales comprising about 127 genera with some 1,750 known species. The word ''cactus'' derives, through Latin, from the Ancient Greek word (''káktos''), a name originally used by Theophrastus for a spiny plant whose identity is now not certain. Cacti occur in a wide range of shapes and sizes. They are native to the Americas, ranging from Patagonia in the south to parts of western Canada in the north, with the exception of ''Rhipsalis baccifera'', which is also found in Africa and Sri Lanka. Cacti are adapted to live in very dry environments, including the Atacama Desert, one of the driest places on Earth. Because of this, cacti show many adaptations to conserve water. For example, almost all cacti are succulents, meaning they have thickened, fleshy parts adapted to store water. Unlike many other succulents, the stem is the only part of most cacti ...

Native Species
In biogeography, a native species is indigenous to a given region or ecosystem if its presence in that region is the result of only local natural evolution (though often popularised as "with no human intervention") during history. The term is equivalent to the concept of indigenous or autochthonous species. A wild organism (as opposed to a domestication, domesticated organism) is known as an introduced species within the regions where it was Human impact on the environment#anthropogenic, anthropogenically introduced. If an introduced species causes substantial ecological, environmental, and/or economic damage, it may be regarded more specifically as an invasive species. A native species in a location is not necessarily also endemism, endemic to that location. Endemic species are ''exclusively'' found in a particular place. A native species may occur in areas other than the one under consideration. The terms endemic and native also do not imply that an organism necessarily first o ...
