Parodia uhligiana is a species of plant in the genus Parodia in the cactus family(Cactaceae). The specific epithet uhligiana honors the cactus importer Karlheinz Uhlig from Rommelshausen .
description
Parodia uhligiana grows individually. The light to dark gray-green cylindrical shoots reach heights of growth of up to 20 centimeters and diameters of up to 10 centimeters. In old age they will lie leaning against the ground and are then up to 33 centimeters long. The ribs are (almost) completely dissolved in spirally arranged, up to 10 millimeters high, conical cusps. The almost round to slightly oval areoles on them are covered with white wool and quickly bald. The thorns are more or less clearly thickened at their base, protrude clearly beyond the apex of the shoot and cover it completely. The seven to twelve initially mostly black to dark brown or dark reddish brown central spines later become grayish red or gray black. They have a length of up to 6 centimeters. The 28 to 40 white radial spines are 0.8 to 1.8 inches long.
The flowers that appear near the apex of the shoots reach a diameter of 5 to 7 centimeters and lengths of 4 to 4.3 centimeters. Your pericarpel and the flower tube are covered with black bristles. The scars are white-pale yellow. The more or less spherical fruits have a diameter of 4 to 6 millimeters. The fruits contain dark brown, more or less spherical and 0.35 to 0.55 millimeters long seeds .
Distribution and systematics
Parodia uhligiana is widespread in the Argentine province of Salta near Amblayo at altitudes of around 3400 meters.
The first description published by Curt Backeberg in 1963 was invalid according to Article 8.4 of the International Code of Botanical Nomenclature , as Backeberg had not given a nomenclatory type . The species, which was listed as a synonym of Parodia nivosa in the cactus lexicon of 2005, was re-described in 2006 by Lothar Diers and Walter Rausch based on material collected by Alfred Bernhard Lau in 1971 at the original site .
