They are up to 9 millimeters long and cannot be divided into central and radial spines.

The narrow, funnel-shaped, sulfur-yellow flowers have a whitish yellow base. They often appear in clusters of up to six individual flowers. The flowers are 2 centimeters long and 1.5 centimeters in diameter. Your pericarpel is bald or almost bald.
