Lobivia mamillosa is a species of cactus from Bolivia.^[1]

Description

Lobivia mamillosa has a solitary growth habit, with globe-shaped stems up to 30 cm (12 in) tall. The stems are dark green, with a diameter of up 8 cm (3.1 in) across, and have 13–17 deep ribs, formed into tubercles. The rounded areoles are spaced up to 12 mm (0.5 in) and produce yellowish spines with brown tips, the one to four central spines being up to 10 mm (0.4 in) long and the 8–12 radial spines 5–10 mm (0.2–0.4 in) long. The flowers are white with rose tips. They are large in relation to the diameter of the stems, up to 8 cm (3.1 in) across and 13–18 cm (5.1–7.1 in) long.^[1]

Two subspecies are recognized. Subspecies mamillosa is shorter (typically only up to 6 cm (2 in) tall) with 17 ribs. Subspecies silvatica is taller and has fewer ribs.^[1]

Distribution

Lobivia mamillosa is widespread in the Bolivian departments of Chuquisaca and Tarija at altitudes of 1500 to 3000 meters.

Taxonomy

Lobivia mamillosa was first described in 1907 by the German botanist Max Gürke. E. silvatica F.Ritter was included in E. mamillosa as the subspecies silvatica by Pierre Braun and E. Esteves Pereira in 1995.^[1] The circumscription of Echinopsis remains controversial; the genus is accepted not to be monophyletic.^[2]
