Description
editPygmaeocereus bieblii grows individually with spherical, green shoots up to 5 cm (2.0 in) in diameter that barely protrude from the ground. The 10 to 25 barely recognizable ribs are divided into wart-like humps. The single central spine, which is 2 to 4 mm (0.079 to 0.157 in) long and 1 mm (0.039 in) in diameter, may also be missing. The 3 to 10 comb-shaped radial spines are white to dark yellow and 1 to 1.5 mm (0.039 to 0.059 in) long.
The broad, funnel-shaped, white flowers are 6 to 7 cm (2.4 to 2.8 in) long and 4.5 to 6 cm (1.8 to 2.4 in) in diameter. Its flower tube is long and slender. The 6 to 10 mm (0.24 to 0.39 in) long fruits are greenish red to brownish.[3]
