Kadenicarpus horripilus is a species of plant in the family Cactaceae. [3]
It is an endangered species, threatened by habitat loss.
Kadenicarpus horripilus often grows sprouting with olive-green, spherical to elongated spherical bodies and fibrous roots. The bodies reach growth heights of 7 to 18 cm (2.8 to 7.1 in) and a diameter of 4 to 6.5 cm (1.6 to 2.6 in). Their clearly pronounced conical cusps are 5 to 7 mm (0.20 to 0.28 in) high. The plant usually a single, protruding, straight, whitish central spine that is dark at the tip. It reaches a length of 12 to 18 mm (0.47 to 0.71 in). The 12 to 14 straight radial spines are white with a dark tip, protruding and 9 to 11 mm (0.35 to 0.43 in) long.
The flowers are magenta with a white throat. They are 2.2 to 3.1 cm (0.87 to 1.22 in) long and have a diameter of 2.5 to 3.5 cm (0.98 to 1.38 in). The elongated, greenish-red fruits turn yellowish-brownish when ripe. They are 4 to 6 mm (0.16 to 0.24 in) long and reach a diameter of 3 to 5 mm (0.12 to 0.20 in). [4]
It is endemic to Hidalgo state in Mexico. Its natural habitat is hot deserts.
It was first described as Mammillaria horripila in 1838 by Charles Lemaire. [5] The specific epithet horripilus is derived from the Latin words horrere for 'shudder' and pilus for 'hair' and refers to the thorns of the species. Monserrat Vázquez-Sánchez placed the species in the genus Kadenicarpus in 2019. [6] Further nomenclature synonym are Echinocactus horripilus (Lem.) Lem. (1839), Neolloydia horripila (Lem.) Britton & Rose (1923), Gymnocactus horripilus (Lem. ex C.F.Först.) Backeb. (1951), Thelocactus horripilus (Lem.) Kladiwa (1970), Thelocactus horripilus (Lem.) Kladiwa & Fittkau (1975), Turbinicarpus horripilus (Lem.) V.John & Říha (1983), Bravocactus horripilus (Lem.) ( 1998) and Pediocactus horripilus (Lem.) Halda (1998)
Neolloydia is a formerly recognized genus of cacti. The genus was first erected by Britton and Rose in 1922. Edward F. Anderson regarded Neolloydia as being poorly defined, with the result that species that had at times been included in Neolloydia were afterwards placed in multiple genera, including Coryphantha, Echinomastus, Escobaria, Mammillaria, Sclerocactus, Thelocactus and Turbinicarpus. In his 2001 book, Anderson firmly placed only one species in the genus, Neolloydia conoidea, with another, Neolloydia matehualensis, being regarded as only a variant of N. conoidea. As of December 2022, Plants of the World Online treated Neolloydia conoidea as a synonym of Cochemiea conoidea, and Neolloydia as a synonym of Cochemiea.
Pelecyphora, pincushion cactus or foxtail cactus is a genus of cacti, comprising 20 species. They originate from Mexico and the United States.
Thelocactus is a genus of flowering plants in the cactus family Cactaceae. Members of the genus are native to the arid lands of Central and Northern Mexico.
Turbinicarpus is a genus of very small to medium-sized cacti, which inhabit the north-eastern regions of Mexico, in particular the states of San Luis Potosí, Guanajuato, Nuevo León, Querétaro, Hidalgo, Coahuila, Tamaulipas and Zacatecas.
Cacteae is a tribe of plants of the family Cactaceae found mainly in North America especially Mexico. As of August 2018, the internal classification of the family Cactaceae remained uncertain and subject to change. A classification incorporating many of the insights from the molecular studies was produced by Nyffeler and Eggli in 2010. The main threats to cactus species are poaching, farming, mining developments, and climate change.
