Rebutia
''Rebutia'' is a genus of flowering plants in the family Cactaceae, native to Bolivia and Argentina. The limits of the genus have varied widely, depending on whether genera such as ''Aylostera'' and ''Weingartia'' are included or treated separately. , Plants of the World Online accepted only three species of ''Rebutia''. A very large number of plants that have been treated in cultivation as species of ''Rebutia'' are now generally regarded as varieties, forms or synonyms of a much smaller number of species, or have been transferred to other genera. Plants treated as ''Rebutia'' are generally small, colorful cacti, globular in form, which freely produce flowers that are relatively large in relation to the body. They have no distinctive ribs, but do have regularly arranged small tubercles. They are considered fairly easy to grow and they may produce large quantities of seeds that germinate freely around the parent plant. Taxonomy The genus was designated in 1895 by Karl Moritz Schu ...

Rebutia Minuscula
''Rebutia minuscula'' is a species of cactus from South America found in northern Argentina and Bolivia., p. 605 It is the type (biology), type species of the genus ''Rebutia''. As its synonym ''Rebutia senilis'' it has gained the Royal Horticultural Society's Award of Garden Merit. Its cultivars 'Krainziana', 'Marsoneri' and 'Violaciflora' are also listed as having gained the Award of Garden Merit. The status of the species of ''Rebutia'' is currently uncertain; indeed the genus as defined by Anderson (2001) has been shown to be Polyphyly, polyphyletic. Anderson describes ''R. minuscula'' as consisting of globe-shaped stems with a diameter of up to , forming large clusters. The stem has 16–20 ribs with small but distinct tubercles ("bumps"). Each areole produces 25–30 fine whitish spines, long. As in other species of ''Rebutia'', the flowers are not produced at the top of the stem, but from around the base. They are red, up to long. Other authorities include synonyms such a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Aylostera
''Aylostera'', is a genus of cactus, native to central Bolivia and north western Argentina. ''Aylostera'' was formerly sunk into a broadly Circumscription (taxonomy), circumscribed genus ''Rebutia'', but Molecular phylogenetics, molecular phylogenetic studies from 2007 onwards showed that when defined in this way, ''Rebutia'' was not Monophyly, monophyletic, leading to the resurrection of ''Aylostera''. A 2023 classification of the tribe Cereeae placed it as the only genus in the subtribe Aylosterinae. It was formerly placed in the subtribe Rebutiinae. Description ''Aylostera'' species are small cacti with globular stems. The stems may or may not have ribs; this feature can vary even within a species. Their flowers are of various colours. A key feature that distinguishes ''Aylostera'' from ''Rebutia'' is that the Hypanthium, pericarpels and Receptacle (botany), receptacles (which together form a structure that is often referred to as the 'flower tube') are hairy, rather than Glabr ...

Rebutia Fabrisii
''Rebutia fabrisii'' is a species of ''Rebutia'' found in Argentina. Description ''Rebutia fabrisii'' is a clustered cactus with globose stems that measure 1 to 2 centimeters in diameter and have fibrous roots. Its 15 spiral ribs are divided into humps, with almost circular areoles that range in color from white to yellow.

Weingartia
'' Weingartia'' is a genus in the family Cactus, Cactaceae, with species native to Bolivia and Argentina. It was formerly included in ''Rebutia'', but Molecular phylogenetics, molecular phylogenetic evidence suggested that it was distinct from that genus. , it was treated as separate genus by Plants of the World Online, and recognized as an alternative generic name in the third edition of the ''CITES Cactaceae Checklist''.

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 ...

Pierre Rebut
Pierre Rebut (1827-1902) was a French botanist who specialized in cacti. The genus ''Rebutia'' is named after him. He was born in France in the year 1827 and died in the year 1902. He was awarded a gold medal by the Côte-d'Or Society of Horticulture and Arboriculture for having a large collection of cacti. In addition to cacti, his personal collection also included ''Crassula'', ''Aloe'', ''Agave'', and ''Mesembryanthemum''. His collection was also considered noteworthy by the Lyonnais The Lyonnais (, ) is a historical province of France which owes its name to the city of Lyon. The geographical area known as the ''Lyonnais'' became part of the Kingdom of Burgundy after the division of the Carolingian Empire. The disintegra ...
