The central spine can reach up to 7.5 cm (3.0 in) long, while the three to eight radial spines reach up to 4.5 cm (1.8 in) in length.

Its cup-shaped, yellow flowers can grow up to 4.5 cm (1.8 in) long and 3.5 cm (1.4 in) in diameter. The spherical fruits are yellow and can reach up to 4 cm (1.6 in) in length.^[4]^[5]
