Description
Species in the genus Uebelmannia grow individually and practically never branch. Their spherical to cylindrical shoots reach heights of growth of up to . The epidermis is smooth, papillate, granular or covered with squamous deposits of wax. The numerous ribs are mostly sharp-edged, but sometimes also divided into bumps.

The small, short, funnel-shaped flowers are yellow. They appear near the shoot tip and open during the day. The flower tube are covered with a few areoles, from which dense wool and few bristles arise.

The spherical to cylindrical, yellow or red, berry-shaped fruits are bare at the base and covered with wool and bristles towards the top. They are thin-walled, dry when ripe and have no remains of flowers. The fruits contain cap-shaped, shiny black to reddish-brown seeds.
