• ETYMOLOGY
“Wrapped candle wax with cephalium (head)”, because the genus has a cephalium which is literally buried, sunk into the stem.
• DESCRIPTION
A genus of erect, semi erect or creeping plants, branching from the base or not (according to species), stems globular or elongated to columnar. Areoles rather small and close to each other, spines variable. Cephalium lateral or apical, more or less embedded in the stem, consisting of wool and robust bristles, wherein the flowers appear.
Flowers nocturnal, self sterile, pollinated by bats and moths (or diurnal in the subgenus Buiningia and so pollinated by hummingbirds), tubular, bell-shaped or funnel-shaped, white, pinkish-white, greenish-white, greenish yellow or purplish red. The fruits are fleshy berries, globular or club-shaped, naked, expelled when ripe and opening through a basal pore. Seeds globose to pyriform, tuberculate, black, mainly dispersed by ants (myrmecochory), also by lizards (saurochory).
• HABITAT
The genus Coleocephalocereus grows endemically in Brazil among rocks, on granitic outcrops and often slightly sloped terraces, in cracks where pockets of humus accumulate, also in the caatinga (dry thorn Brazilian forest), together with other cacti and succulents, from 200 m up to 800 m in altitude. Temperatures vary little throughout the year, and the relative humidity is quite high.
• DISTRIBUTION
Brazil (Bahia, Espirito Santo, Minas Gerais, Rio de Janeiro, Sao Paulo).

• ETYMOLOGY
Because the genus (misspelled) is native to the region of the Cochimi Indians in Baja California, Mexico.
• DESCRIPTION
A genus of branched plants, many erect or prostrate elongated stems with distinct tubercles spirally arranged, not furrowed. Central spine hooked or straight (only in C. halei).

• ETYMOLOGY
“Closed cactus” referring to the tubular flowers that open only very slightly.
• DESCRIPTION
A genus of shrubby plants with erect, often slender, cylindrical stems, shape variable, pendulous, prostrate, creeping or pending. Central and radial spines poorly differentiated.
Flowers diurnal, narrowly tubular, almost closed, more or less hairy, straight or slightly curved, yellow, orange, red to purplish red, pink, green, or sometimes bicoloured or even tricoloured, pollinated by hummingbirds. Fruits small, scaly, spherical, splitting when ripe. Seeds many, small, shinyrblack, globose to pyriform (pear-shaped), striate, often foveolate.
• HABITAT
The genus Cleistocactus grows in dry, semi-arid woodlands, among thorny bushes, or in full sun, mainly in the Andes from 100 m up to 3000 m in altitude. The species found at higher altitudes (C. hyalacanthus, C. jujuyensis) are found in high valleys, in mineral, sometimes schistose substrates. Others (e.g. C. ritteri) live in deep valleys with a tropical climate. Some species such as C. baumannii are highly variable and a subspecies (C. baumannii subsp. horstii) lives at 100-200 m above sea level in an area near the Grand Pantanal wetlands in Brazil, where the average annual temperature is 25°C, and rainfall is than 1000 mm/year.

• ETYMOLOGY
“Candle of Cipo”, because the genus comes from Serra do Cipo in Minas Gerais, Brazil.
• DESCRIPTION
A genus of shrubby plants, shortly columnar, some species are branched with woody stems. Spines sometimes absent, areoles rounded, sometimes woolly. Number of ribs variable (4-21).
Flowers nocturnal, remaining open the next day, tubular, glaucous, white, pollinated by bats. Fruits globose to ovoid, blue, indehiscent, translucent watery pulp (main characteristic of the genus), and keeping the remains of the dried perianth. Seeds rough, cochleariform (spoon-shaped), black, embossed, strongly tuberculate, domed or conical. Seed dispersal takes places by birds and bats.
• HABITAT
The genus Cipocereus grows endemically from 500 m up to 1500 m in altitude, in the mountains of Minas Gerais in Brazil, on rocky areas, and white quartz sand, in the shade of shrubs, where there is an accumulation of humus. Mists that form at these altitudes contribute to “water” the semi-arid zone, populated by other cacti, bromeliads and terrestrial orchids, as well as mosses and lichens.
• DISTRIBUTION
Brazil (Minas Gerais).

Currently 5 recognised species + one subspecies:
– Cipocereus bradei (Backeb. & Voli) Zappi & N.p.Tayior 1991
– Cipocereus crassisepalus (Burning & Brederoo) N.p.Tayior & Zappi 1991

• ETYMOLOGY
“Wax candle”, referring to the cylindrical stems of this genus, having the shape of a wax candle.
• DESCRIPTION
Shrubby or treelike plants, usually much branched, erect or prostrate depending on the species and often with a welldefined trunk. Stems angular, ribbed and well developed, with rather large areoles, generally woolly but not hairy. Spines often numerous and aciculate. Pseudocephalium densely woolly, present in only one species, Cereus mortensenii.
Flowers nocturnal, funnel-shaped, white, whitish purple or yellow, pollinated by Sphingidae (Cereus aethiops, C. fernambucensis, C. hildmannianus), bats (Glossophagasoricina, G. longirostris and Leptonycteris curasoae for Cereus repandus; Artibeus iituratus, A. jamaicensis and Glossophaga longirostris for Cereus hexagonus) during the night, and hummingbirds (Chlorostiibon aureiventris for C.jamacaru) when they are still open in the morning. Fruits globose to ovoid, fleshy, with a lateral dehiscence, highly variable in colour, may be greenish, yellow, red or bluish, keeping or not keeping the remains of dried perianth. Seeds large, black, rough, strongly tuberculate. Seed dispersal (for Cereus stenogonus and probably many others) provided by – among others and in some areas – the tapir (Tapirus terrestris).
• HABITAT
As circumscribed here, the genus Cereus grows in a variety of habitats (some species such as C. validus having a wide distribution), mainly in the shade, in thorny thickets and dry forests of South America, also in full sun on rocky hills of volcanic origin (C. insularis), plains, on various soils, granitic, sandy, etc., almost from the sea level up to 3200 m in altitude.
