but this species has a spathe with shorter, more pubescent hairs which can be rubbed off, and is also somewhat robuster and larger in size. B. pubispatha also grows much faster. B. eriospatha can also be found growing in this region. Distribution The species is mostly restricted to eastern highlands of the state of Paraná, with small populations in the south of São Paulo state. As of 2017, it has been recorded from only ten localities. Within Paraná it occurs in the municipalities of Antônio Olinto, Carambeí, Jaguariaíva, Palmeira, Ponta Grossa, Sengés and Tibagi. Within São Paulo it occurs in the municipalities of Paranapanema and Itararé. Within the extent of occurrence, an area of approximately 6000 km2, it is calculated to occupy some 1300 km2 (the area of occupancy), giving it an abundance of 21%, which is reasonably low compared to other species of Butia. The specimen Luederwaldt no. 12267 Burret cited in 1930 was collected, according to him, in Raiz da Serra (in modern Cubatão), São Paulo, but the no. 12267 specimen Glassman had found in the late 1960s in the herbarium of São Paulo was labelled as being collected in Rio Grande do Sul, thus Glassman concluded that the two specimens might not be the same, despite bearing the same collection numbers. Because of this, Glassman concluded that Butia microspadix was native to the states of Rio Grande do Sul and Paraná, and possibly São Paulo if one accepted Burret's description (he apparently didn't read Burret's statement that the Sellow collection was also likely made in São Paulo). Because of the belief that this species was found in Rio Grande do Sul, a number of sources also state that it (probably) occurs in Santa Catarina state, which lies between Rio Grande do Sul and Paraná, although it has never been seen there. In 2014, however, Soares et al. and a curator of the São Paulo herbarium, Maria Mamede, pointed out that Luederwaldt had never been to Rio Grande do Sul, and spent his time in Brazil exclusively collecting in the vicinity of São Paulo, which meant that the specimen had simply been mislabelled. Habitat It is found in dry grasslands or steppes known as campos gerais, where its unassuming habitus and thin leaflets makes it difficult to find camouflaged amongst the grass. It may also sometimes be found growing on rocky outcrops. It grows in full sun and
