Parodia lenninghausii is a species of plant in the genus Parodia from the cactus family(Cactaceae). The epithet of the species honors Frederico Guillermo Lenninghaus, a cactus collector from Porto Alegre , who sent the first specimens of the species to the Kakteen-Haage company in Erfurt in1894.
description
Parodia lenninghausii usually grows in large groups with cylindrical, green shoots that reach heights of up to 60 centimeters (or higher) and a diameter of between 7 and 10 centimeters. The crooked shoot tip is not very woolly. The approximately 30 to 35 straight, low, blunt ribs are covered with closely spaced areoles , from which light to deep yellow to brown thorns arise, which are very fine and straight to slightly curved. The 3 to 4 central spines are 2 to 5 inches long. The 15 to 20 (or more) radial spines are between 5 and 10 millimeters long.
The lemon yellow flowers are 5 to 6 inches long and reach the same diameter. Your pericarpel and the flower tube are covered with dense brown wool and bristles. The scar is light yellow. The spherical fruits contain bell-shaped, brownish red seeds .
Spread and endangerment
Parodia lenninghausii is common in Brazil in the state of Rio Grande do Sul on steep rock faces in humid gorges.
In the Red List of Threatened Species of IUCN is the species as " Endangered (EN) ," d. H. listed as endangered.
Botanical history
The species was first mentioned in 1895 as Pilocereus leninghausii by Karl Moritz Schumann , who ascribed the name to Friedrich Ferdinand Haage . However, Schumann assumed that the species should be assigned to the genus Echinocactus , and published the name Echinocactus leninghausii in the same year, but without providing a valid description. A year later, the first brief description of the species appeared in a catalog from the Kakteen-Haage company under the name Pilocereus len n inghausii . Various recombinations into other genera followed. Nathaniel Lord Britton and Joseph Nelson Rose placed them in the genus Malacocarpus in 1922 , Alwin Berger in the genus Notocactus in 1929 , Walter Heinrich in 1940 in the genus Eriocephala and Fred H. Brandt in 1982 in the genus Parodia . With reference to the spelling "lenninghausii" published in the Haage catalog in 1896, Urs Eggli and Andreas Hofacker corrected the incorrect spelling of the specific epithet, which can be traced back to Guillermo Lenninghaus, through a new combination .
