Soehrensia quadratiumbonata is a species of Soehrensia found in Bolivia.[2]
Description
[edit]Soehrensia quadratiumbonata grows as a shrub with several upright branches emerging from the base, reaching heights of up to 1 meter. The cylindrical green stems are 4 to 5 cm (1.6 to 2.0 in) in diameter. There are nine to twelve ribs with cross-grooves. The round, brown areoles on the ribs are about 1 cm (0.39 in) apart, from which white, needle-like spines with brown tips emerge. Typically, there is a single, robust, 1 to 4-centimeter-long central spine, and seven to ten radial spines measuring 0.4 to 1 cm (0.16 to 0.39 in) in length.
The long, funnel-shaped white flowers open at night but not fully. The dark green fruits are up to 3.5 cm (1.4 in) long and wide.[3]
Distribution
[edit]Soehrensia quadratiumbonata is found in the Bolivian departments of Chuquisaca and Santa Cruz at elevations of 1000 to 1900 meters.
Taxonomy
[edit]First described as Trichocereus quadratiumbonatus by Friedrich Ritter in 1980, the species name derives from the Latin words quadratus (four-sided) and umbonatus (navel-like), referring to the almost rectangular ribs of the plant.[4] Boris O. Schlumpberger reclassified the species into the genus Soehrensia in 2012.[5]
