Cephalium
Cephalium is a frequently brightly coloured structure of wool and bristle at the growing tip of certain cacti. It is most commonly found on cacti of the genus ''Melocactus'' and can take a number of colours, forms and shapes. The cephalium will only begin growing after a cactus has reached a certain size or age. Once flowering begins the flower buds will form from the cephalium.

Melocactus
''Melocactus'' (melon cactus), also known as the Turk's cap cactus, is a genus of cactus with about 30–40 species. They are native to the Caribbean, western Mexico through Central America to northern South America, with some species along the Andes down to southern Peru, and a concentration of species in northeastern Brazil., pages=456–467 The first species was named by Carl Linnaeus in 1753, as ''Cactus melocactus''. When the genus was separated from ''Cactus'', the pre-Linnaean name ''Melocactus'' was used. Acting on the principle of priority, in 1922 Nathaniel Britton and Joseph Rose resurrected Linnaeus' ''Cactus''. However, the 1905 Vienna botanical congress had already rejected the name ''Cactus'', so this name was not available, and ''Melocactus'' Link & Otto is the correct genus name. Mature plants are easily recognizable by their cephalium, a wool- and bristle-coated structure at the apex of the plant, containing a mass of areoles from which the small flowers g ...

Melocactus Matanzanus
''Melocactus matanzanus'', common name dwarf Turk's-cap cactus or Turk's-cap cactus, is a cactus in the genus ''Melocactus'' of the family Cactaceae. The epithet ''matanzanus'' is derived from the Cuban province of Matanzas. Description ''Melocactus matanzanus'' is a perennial fleshy globose plant. It can reach a height of and a diameter of . On the bright green body there are 8–9 (or more) ribs. The thorns are brownish-gray or white. The central spine is up to long, while the 7 to 8 radial spines are long. When the plant has reached a certain age it shows at the growing tip a cephalium (hence the common name of "Turk's Cap"), a globose structure covered with reddish-brown bristles. This structure, where the flower buds will form, reaches a height of up to and a diameter of . The flowers are carmine, about long. Distribution This plant is native to the north-central area of Cuba Cuba ( , ), officially the Republic of Cuba ( es, República de Cuba, links=no ), is a ...

Espostoa Lanata
''Espostoa lanata'' (= Wooly Espostoa) is a species of cactus of the genus '' Espostoa''. Its common names are Peruvian old man cactus, cotton ball cactus, snowball cactus, snowball old man. Habitat Its original habitat is from southern Ecuador to the northern Peru on the west slopes of the Andes mountains. Description ''Espostoa lanata'' is a columnar cactus. It looks like ''Cephalocereus senilis'' (the Old Man of Mexico) : it is a densely hairy species, covered by a warm woolly coat and well adapted to high altitudes. The main difference is the presence of sharp spines on ''Espostoa''. It is widespread in its habitat and quite variable in size and spines, and for this reason it has received several names. The plant is a column up to 7 meters tall in the wild, but only 3 meters when cultivated. The diameter is from 5 to 20 cm. There are 18 to 25 ribs. The ribs and the sharp are mainly hidden by tissue woolly. It branches only after several years. It flowers at ni ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cacti
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 spines, ...

Arrojadoa Penicillata
''Arrojadoa'' is a genus of cacti, comprising 6 species and several varieties. It is named after the Brazilian botanist Miguel Arrojado Lisboa (1872–1932) who was superintendent of the Brazilian Railways at the time that Britton and Rose described the genus in 1920. The genus occurs only in northern Brazil and is found at rocky places, under shrubs, which support their frail stalk. They are subtropical plants, with very little frost tolerance. Description The species often have frail stalks that can be upright or procumbent, reaching 2 m high and about 2 to 5 cm thick. There are from 10 to 15 ribs, and ramifications are rare, and usually occur from the base. The flowers are nocturnal and tube-like, measuring 1 to 3 cm in length and 0.5 to 1 cm in diameter. Flower colors can be pink or carmine. The fruit is berry A berry is a small, pulpy, and often edible fruit. Typically, berries are juicy, rounded, brightly colored, sweet, sour or tart, and do not have a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
