Description
Glandulicactus uncinatus typically grows alone, with bluish-green, spherical to cylindrical shoots ranging from 18 to 27 cm (7.1 to 10.6 in) in height and 10 to 12 cm (3.9 to 4.7 in) in diameter. It has about 13 wavy ribs with pronounced tubercles, and sharp furrows between the ridges. The one to five central spines are hook-shaped, yellow with a reddish tip, and 8 to 13 cm (3.1 to 5.1 in) long, pointing upwards or obliquely outwards. There are seven to ten radial spines, 2.5 to 5 cm (0.98 to 1.97 in) long, with the upper ones flat and brightly colored, and the lower ones hook-shaped and somewhat purple.
Its funnel-shaped flowers, reddish-brown in color, emerge from the furrows of the areoles. They are 2 to 4 cm (0.79 to 1.57 in) long and have a diameter of 2.5 to 3 cm (0.98 to 1.18 in).[3]

Taxonomy
The species was first described as Echinocactus uncinatus by Ludwig Georg Karl Pfeiffer in 1848.[5] The specific epithet "uncinatus" comes from Latin, meaning "hooked," referring to the hook-shaped central thorns of the species. Nathaniel Lord Britton and Joseph Nelson Rose moved the species to the genus Ferocactus in 1922.[6] This species was moved to the genus Glandulicactus by Curt Backeberg.
