description
Eriosyce napina grows individually with depressed spherical to slightly elongated dark green to green-brown shoots and reaches a diameter of 2 to 4 centimeters. The parting is bare or somewhat woolly. The root is a large, bulbous taproot that is separated from the shoot with a narrow neck. The ribs are divided into low humps. The areoles on it are somewhat sunken. There are few to numerous horn-colored to black thorns that lie against the shoot surface or radiate somewhat. They are 2 to 5 millimeters long. A single thorn is a little more central.
The funnel-shaped flowers are light yellow to sometimes light reddish and appear from young areoles. Your pericarpel and the flower tube are covered with whitish wool and bristles. The elongated fruits open with a basal pore.
