Description

Plants in the genus ''Uebelmannia'', individual plants grow without branching and form spherical to cylindrical shoots that can reach heights of up to . The plant's surface can be smooth, papillate, granular, or covered with waxy deposits. Most plants have sharp-edged ribs, although some may have ribs that are divided into bumps. Each plant has two to seven spines that emerge from the areoles, which are arranged in a protruding, spreading, or comb-like pattern. These spines can be straight or slightly curved. The small, short, funnel-shaped flowers of ''Uebelmannia'' are yellow and typically bloom near the tip of the shoot during the day. The flower tubes are covered with a few areoles, from which dense wool and a few bristles emerge. The fruits of ''Uebelmannia'' are spherical to cylindrical, yellow or red in color, and resemble berries. They are bare at the base but covered with wool and bristles towards the top. When ripe, the fruits are thin-walled and dry, with no remnants of the flowers. Inside the fruits are cap-shaped, shiny black to reddish-brown seeds.
