Orto Botanico Dell'Università Di Catania
The Orto Botanico dell'Università di Catania (16,000 m²), also known as the Hortus Botanicus Catinensis, is a botanical garden in Catania, Sicily, southern Italy. It is operated by the University of Catania botany department. This institution is a member of BGCI, with international identification code CAT. History Realization of a garden was first attempted in 1847 with a purchase of land on the city outskirts, but the revolutions of 1848 rapidly led to its dispersion. In 1858 the garden was established by founder and director, Benedictine Monk and botanist Francis Roccaforte Tornabene (1813–1897), with first plantings in 1862 of specimens obtained from other botanical gardens in Sweden, France, Naples, and Palermo. It was enlarged in 1865 with a new area dedicated to cultivation of indigenous Sicilian species, and in the early 1900s further enhanced by creation of the Giardino Botanico "Nuova Gussonea" on Mount Etna for cultivation of native mountain plants. The main gar ...

Greenhouse
A greenhouse (also called a glasshouse, or, if with sufficient heating, a hothouse) is a structure with walls and roof made chiefly of Transparent ceramics, transparent material, such as glass, in which plants requiring regulated climatic conditions are grown.These structures range in size from small sheds to industrial-sized buildings. A miniature greenhouse is known as a cold frame. The interior of a greenhouse exposed to sunlight becomes significantly warmer than the external temperature, protecting its contents in cold weather. Many commercial glass greenhouses or hothouses are high tech production facilities for vegetables, flowers or fruits. The glass greenhouses are filled with equipment including screening installations, heating, cooling, and lighting, and may be controlled by a computer to optimize conditions for plant growth. Different techniques are then used to manage growing conditions, including air temperature, relative humidity and vapour-pressure deficit, in ord ...

Lophophora Williamsii
The peyote (; ''Lophophora williamsii'' ) is a small, spineless cactus which contains psychoactive alkaloids, particularly mescaline. ''Peyote'' is a Spanish word derived from the Nahuatl (), meaning "caterpillar cocoon", from a root , "to glisten". p. 246. See peyotl in Wiktionary. Peyote is native to Mexico and southwestern Texas. It is found primarily in the Sierra Madre Occidental, the Chihuahuan Desert and in the states of Nayarit, Coahuila, Nuevo León, Tamaulipas, and San Luis Potosí among scrub. It flowers from March to May, and sometimes as late as September. The flowers are pink, with thigmotactic anthers (like ''Opuntia''). Known for its psychoactive properties when ingested, peyote has at least 5,500 years of entheogenic and medicinal use by indigenous North Americans. Description The various species of the genus ''Lophophora'' grow low to the ground and they often form groups with numerous, crowded shoots. The blue-green, yellow-green or sometimes reddish-g ...

Leuchtenbergia Principis
''Leuchtenbergia'' is a genus of cactus which has only one species, ''Leuchtenbergia principis'' (agave cactus or prism cactus). It is native to north-central Mexico ( San Luis Potosi, Chihuahua). The genus is named after Maximilian Eugen Joseph (1817–1852), Duke of Leuchtenberg and amateur botanist. It is very slow-growing but can eventually grow up to 70 cm high, with a cylindrical stem which becomes bare and corky at the base with age. It has long, slender, grayish-green tubercles 6–12 cm long, with purplish-red blotches at their tips. The tubercles are topped with papery spines, making the plant resemble an agave; old, basal tubercles dry up and fall off. After four years or so, yellow, funnel-shaped flowers 5–6 cm diameter may be borne at the tubercle tips. The fruit is smooth and green, 3 cm long and 2 cm broad. It has a large, tuberous taproot. Taxonomy It is related to the genus ''Ferocactus ''Ferocactus'' is a genus of large barrel- ...

Echinocactus Grusonii
''Echinocactus grusonii'' or ''Kroenleinia grusonii'', popularly known as the golden barrel cactus, golden ball or mother-in-law's cushion, is a species of barrel cactus which is endemic to east-central Mexico. It is rare and endangered in the wild, where it is found near Mesa de León in the state of Querétaro, and in the state of Hidalgo. The population was critically reduced in the 1990s, by the creation of the Zimapán Dam and reservoir in Hidalgo. The cactus grows in volcanic rock on slopes, at altitudes around . Taxonomy ''Echinocactus grusonii'' belongs to the small genus ''Echinocactus'', which together with the related genus ''Ferocactus'', are commonly referred to as barrel cacti. The species was first described by German plantsman Heinrich Hildmann in 1891. While sometimes referred to as golden ball, this species is not to be confused with '' Notocactus leninghausii'' which have fuzzy, harmless spines and are native to Brazil and Paraguay. Recent phylogenetic stu ...

Cereus (plant)
''Cereus'' ( "serious") is a genus of cacti (family Cactaceae) including around 33 species of large columnar cacti from South America. The name is derived from Greek (κηρός) and Latin words meaning "wax", "torch" or "candle". ''Cereus'' was one of the first cactus genera to be described; the circumscription varies depending on the authority. The term "cereus" is also sometimes used for a ceroid cactus, any cactus with a very elongated body, including columnar growth cacti and epiphytic cacti. Description ''Cereus'' are shrubby or treelike, often attaining great heights ('' C. hexagonus, C. lamprospermus, C. trigonodendron ''up to ). Most stems are angled or distinctly ribbed, ribs long, usually well developed and have large areoles, usually bearing spines. Cephalium is not present; '' C. mortensenii'' develops pseudocephalium. The flowers are large, funnelform, long, usually white, sometimes pink, purple, rarely cream, yellow, greenish, and open at n ...

Blossfeldia Liliputana
''Blossfeldia'' is a genus of cactus (family Cactaceae) containing only one species, ''Blossfeldia liliputiana'', native to South America in northwestern Argentina (Jujuy, Salta, Tucumán, Catamarca and Mendoza Provinces) and southern Bolivia ( Santa Cruz and Potosí Departments). It grows at 1,200–3,500 m altitude in the Andes, typically growing in rock crevices, and often close to waterfalls. It is of note as the smallest cactus species in the world, with a mature size of around 10–12 mm diameter. The flowers are white or rarely pink, 6–15 mm long and 5–7 mm diameter. The genus ''Blossfeldia'' has been divided into many separate species; however most morphological evidence supports that the genus is monotypic, and contains only ''Blossfeldia liliputiana''. The species is named after the fictional country of Lilliput, where all of the inhabitants are minute. Taxonomy The genus and species were first described in 1937 by Erich Werdermann after be ...

Astrophytum Capricorne
''Astrophytum capricorne'', the goat's horn cactus, is a species of flowering plant in the cactus family Cactaceae, that is native to the Coahuila regions of Northern Mexico. Growing to tall by wide in a ball or oval shape, it is grey-green in colour with 7 to 9 prominent ribs, very long twisted spines and yellow flowers with a red centre in summer. The common name of goat's horn cactus corresponds to the species identifier ''capricorne'' (''capri'' meaning “goat” and ''corne'' meaning “horn”) referring to the curved spines that are said to resemble a goat's horns. This species is designated as of "least concern" by the IUCN as it is widely distributed in the Chihuahuan desert. Cultivation This species is grown, typically from seed, as an ornamental plant as it produces large, attractive yellow flowers with red central regions. Some cultivars bear white flecking on the plant body while others lack this feature. Though tolerant of cold temperatures, it must be grown in ...

Aizoaceae
The Aizoaceae, or fig-marigold family, is a large family of dicotyledonous flowering plant Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. The term "angiosperm" is derived from the Greek words ('container, vessel') and ('seed'), and refers to those plants th ...s containing 135 genus, genera and about 1800 species. They are commonly known as ice plants or carpet weeds. They are often called vygies in South Africa and New Zealand. Highly Succulent plant, succulent species that resemble stones are sometimes called mesembs. Description The family Aizoaceae is widely recognised by taxonomists. It once went by the botanical name "Ficoidaceae", now disallowed. The APG II system of 2003 (unchanged from the APG system of 1998) also recognizes the family, and assigns it to the order Caryophyllales in the clade core eudicots. The APG II system also classes the former families Mesembryanthemaceae Fenzl, S ...

Euphorbiaceae
Euphorbiaceae, the spurge family, is a large family of flowering plants. In English, they are also commonly called euphorbias, which is also the name of a genus in the family. Most spurges, such as ''Euphorbia paralias'', are herbs, but some, especially in the tropics, are shrubs or trees, such as ''Hevea brasiliensis''. Some, such as ''Euphorbia canariensis'', are succulent and resemble cacti because of convergent evolution. This family has a cosmopolitan global distribution. The greatest diversity of species is in the tropics, however, the Euphorbiaceae also have many species in nontropical areas of all continents except Antarctica. Description The leaves are alternate, seldom opposite, with stipules. They are mainly simple, but where compound, are always palmate, never pinnate. Stipules may be reduced to hairs, glands, or spines, or in succulent species are sometimes absent. The plants can be monoecious or dioecious. The radially symmetrical flowers are unisexual, w ...

Cactaceae
A cactus (, or less commonly, cactus) is a member of the plant family Cactaceae, a family comprising about 127 genera with some 1750 known species of the order Caryophyllales. 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. Although some species live in quite humid environments, most cacti live in habitats subject to at least some drought. Many live in extremely dry environments, even being found in 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 where this vital process takes place. Most species of cacti have lost true leaves, retaining only Thorns, s ...
