Arthrocereus spinosissimus is a species of cactus in the subfamily Cactoideae from Brazil.[1][2]
Description
Arthrocereus spinosissimus grows upright with basally branching shoots. The up to one meter long, green to bright green shoots reach a diameter of 5 to 6 centimeters. The 16 (or more) ribs are 4 to 5 millimeters high. Numerous, thin, yellowish thorns emerge from the closely spaced areoles. There are 6 to 8 central spines that are usually 2 to 2.8 centimeters, occasionally up to 4.5 centimeters in length, and about 20 radial spines of 0.7 to 0.8 centimeters in length.
The white flowers are between 6 and 7 centimeters long, the fruits between 2.5 and 3 centimeters. [3]
Distribution
Arthrocereus spinosissimus is restricted to the Chapada dos Guimarães National Park in the Brazil ian state of Mato Grosso at altitudes of 800 to 900 meters.[1]
Taxonomy
The first description as Eriocereus spinosissimus by Albert Frederik Hendrik Buining and Arnold J. Brederoo was published in 1977 from Buining's estate.[4] The specific epithet spinosissimus is derived from the superlative of the Latin adjective spinosus for 'thorny'. Friedrich Ritter placed the species in the genus Arthrocereus in 1979.[5]
