Prof. M. Cardenas found this East-Bolivian based genus in 1949 in the mountains of Santiago and described it as Frailea chiquitana two years later. In 1963 C. Backeberg described F. pullispina which grows in the same area. This description remained invalid since no holotype was deposited. According to the present state of knowledge it is valid to assume that this was another description of F. chiquitana. Contrary to most representatives of the genus Frailea, this species does not cultivate cleistogamous blooms. Plants grow isolated or in groups. Single specimen reach a diameter of up to 40mm. The colour of the flower is yellow.
