description
Eriosyce kunzei has green, somewhat flattened spherical to elongated plant bodies that reach a height of 10 to 20 centimeters and a diameter of 13 to 14 centimeters. The sunken part is not covered with thorns . The 16 to 20 blunt ribs are thickened around the long and narrow, 13 to 17 millimeters apart areoles and notched with bumps. The humps are confluent and pointed. The yellowish and later graying thorns are curved upwards to inwards. The 2 to 4 thick central spines are 4.5 to 5 inches long. The 10 to 12 straight radial spines are directed downwards. They are 1.3 to 4.5 inches long, with the top thorns being the longest.
The broad, funnel-shaped flowers are up to 3.5 inches long and wide. Their flower tube is woolly white and has some black bristles. The oil-green pericarpel is covered with brownish reddish scales. The sepals are ivory white and have a reddish central stripe. The elongated, shiny yellowish petals are serrated with a tip. The stamens are white, the stylus is flesh-colored, and the scar somewhat lighter.
The egg-shaped, fleshy fruits are hollow and up to 2 inches long.
