The English summary from Succulenta :

A new Sulcorebutia species from Bolivia is described here by Johan de Vries as Sulcorebutia luteiflora. The plants were discovered in 2009 by the author and his companion Roland Müller in the surroundings of Torre Pampa, an isolated area, west of San Pedro. The plants show exclusively clear yellow flowers, which has led to the name luteiflora. The newly described species differs from S. cantargalloensis by larger and flatter plants, normally not or only sporadically offsetting, a bright colored spination without central spines. Sulcorebutia luteiflora is a very attractive species that will soon find its way into the collections.
