Uebelmannia is a genus of plants from the cactus family(Cactaceae). The botanical name of the genus honors the Swiss cactus gardener Werner Uebelmann .
description
The species of the genus Uebelmannia grow individually and in fact never branch. Their spherical to cylindrical shoots reach heights of growth of up to 75 centimeters. The epidermis is smooth, papillate, granular or with plate-shaped wax deposits. The numerous ribs are usually sharp-edged, but sometimes also divided into cusps. From the areoles arise 2 to 7 spines , which are arranged protruding to spread or in a comb-shape. They can be straight or slightly curved.
The small, short funnel-shaped flowers are yellow. They appear near the tip of the shoots and open during the day. Your pericarpel and the flower tube are covered with some areoles, from which dense wool and a few bristles arise.
The spherical to cylindrical, yellow or red, berry-shaped fruits are bare at their base and covered with wool and bristles towards the tip. They are thin-walled, dry when ripe and have no flower remnants. The fruits contain cap-shaped, glossy black to reddish brown seeds .

The first description was published in 1967 by Albert Frederik Hendrik Buining . The type species of the genus Parodia gummifera Backeb. & Voll was described as early as 1950. All species of the genus are threatened by illegal collection and are therefore listed in Appendix I of the Washington Convention on the Protection of Species .
