Thelocactus lausseri is a species of cactus endemic to Mexico. [1]
Thelocactus lausseri grows as a single, spherical or short, elongated cactus. It has a grey-green body that is 7 to 10 cm (2.8 to 3.9 in) tall and 5 to 8.5 cm (2.0 to 3.3 in) in diameter. The cactus has 8 ribs arranged in a slight spiral. The areoles, which lack glands, are about 5 to 6 mm (0.20 to 0.24 in) in diameter. The rounded warts are 7 to 9 mm (0.28 to 0.35 in) in diameter and 8 to 12 mm (0.31 to 0.47 in) high. It has 20 to 25 radial spines that are 18 to 25 mm (0.71 to 0.98 in) long and silvery-white to yellowish in color. There are 4 central spines (occasionally 6) that are 6 to 10 cm (2.4 to 3.9 in) long, yellow to greyish, straight or slightly curved, and needle-shaped. The flowers are 2.5 to 4.4 cm (0.98 to 1.73 in) long and wide, ranging in color from whitish to light pink with a darker central stripe. The fruits have scales and burst open when dry. The seeds are 2 mm (0.079 in) long and thick. [2]
Thelocactus lausseri is found growing in shrubland on limestone and calcareous soil in the Sierra de las Ovejas, Coahuila, at elevations between 800 and 1500 meters. [3]
It was first described in 1986 by Jan Říha and Josef Busek. The species name lausseri honors the German plant collector Alfons Lausser. [4] [5]
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.
