Description
The grey-green, single plant body, slightly depressed at the top, is spherical and reaches heights of 5 to 8 centimeters with diameters of 7 to 12 centimeters. It has 10 to 12 straight, very sharp ribs on which there are small, cream-colored, elongated-elliptical areoles that are 1.5 centimeters apart. The thorns are grayish brown and often hidden in the areole wool. The upright central spine is up to 2 millimeters long. The 3 to 7 thorns swollen at the base are up to 1.5 millimeters long.
The white to light pink, narrow funnel-shaped flowers, slightly curved above the ovary, are 17 to 20 centimeters long. They appear on the side near the top of the shoot and open at night. The pale green flower tube is up to 15 centimeters long and reaches a diameter of up to 7 centimeters. The elliptical ovary is 15 millimeters long and 8 to 10 millimeters wide. Its purple scales are pointed and have long white and black hairs. The 12 millimeter long style is white like the stamens.
Distribution
''Lobivia ancistrophora'' is widespread near Angosto de Villamontes in the Entre Ríos Municipality in the Tarija Department in Bolivia at altitudes of 600 meters. The distribution area possibly extends as far as Paraguay.
Taxonomy
The first description as ''Echinopsis subdenudata'' was made in 1956 by Martín Cárdenas.
The specific epithet subdenudata is derived from the Latin words sub for "under" and denudatus for "exposed" and refers to the insignificant thorns on the shoots. Boris O. Schlumpberger placed the species in the genus ''Lobivia'' in 2012.
