Cephalocereus tetetzo is a species of cactus from Mexico.
Cephalocereus tetetzo grows in a columnar shape with mostly branching shoots and reaches heights of up to 15 meters. A trunk with a diameter of up to 70 cm (28 in) is formed. The gray-green shoots are 8 to 12 meters long and have a diameter of 18 to 30 cm (7.1 to 11.8 in). The 15 to 20 blunt ribs are slightly rounded. The central spine, which is usually single, is blackish and up to 5 cm (2.0 in) long. The 8 to 13 blackish marginal spines are 1 to 2 cm (0.39 to 0.79 in) long.
The bell- to funnel-shaped flowers appear near the tips of the shoots. They are whitish and 5 to 6 cm (2.0 to 2.4 in) long. Its pericarpel and flower tube are covered with tubercles, scales, wool and bristles. The egg-shaped green fruits are up to 4 cm (1.6 in) long and have thorns. [2]
Cephalocereus tetetzo is distributed in the Mexican states of Puebla and Oaxaca.
The first description as Cereus tetetzo (spelled "Cereus tetazo") was made in 1896 by John Merle Coulter. [3] The specific epithet tetetzo refers to the Spanish common name "Tetetzo". Léon Diguet placed the species in the genus Cephalocereus in 1928. Further nomenclature synonyms are Pilocereus tetetzo (F.A.C.Weber ex J.M.Coult.) F.A.C.Weber ex K.Schum. (1897), Cephalocereus tetetzo (F.A.C.Weber ex K.Schum.) Vaupel (1909), Pachycereus tetetzo (F.A.C.Weber ex K.Schum.) Ochot. (1922), Neobuxbaumia tetetzo (F.A.C.Weber ex J.M.Coult.) Backeb. (1938) and Carnegiea tetetzo (F.A.C.Weber ex J.M.Coult.) P.V.Heath (1992).
Pachycereus is a genus of large cacti native to Central America and Mexico. They form large shrubs or small trees up to 15 m tall, with stout stems up to 1 m in diameter. Pachycereus comes from the ancient Greek παχύς (pachys) meaning "thick" and the Latin cereus meaning "torch".
Bergerocactus emoryi is a species of cactus, known commonly as the golden-spined cereus, golden snake cactus, velvet cactus or golden club cactus. It is a relatively small cactus, but it can form dense thickets or colonies, with the dense yellow spines giving off a velvety appearance when backlit by the sun. From April to May, yellow, green-tinged flowers emerge, which transform into reddish, globular fruit. This species is native to the California Floristic Province, and is found in northwestern Baja California and a small part of California, in San Diego County and on the southern Channel Islands. Where the Mediterranean climate of the California Floristic Province collides with the subtropical Sonoran Desert near El Rosario, hybrids with two other species of cacti are found. It is the sole member of the monotypic genus Bergerocactus, named after German botanist Alwin Berger.
