The epithet refers to the plant’s resemblance to species of the parasitic genus  StrigaLour.(witchweed) in the Orobanchaceae.   Distribution and habitat.  Pombalia strigoidesis restricted to campos rupestres, grasslands and savannas of Chapada dos Veadeiros region, northeastern Goiás state, Brazil(see  Figure 3).   Phenology. The species has been collected with flowers and fruits from September to November, with a single flowering record in August.   Conservation status. Although there are records of  Pombalia strigoidespopulations within the limits of conservation units, the species has nonetheless a restricted distribution in a region marked by the conversion of natural ecosystems into agricultural areas. According to IUCN (2012)criteria B1b(i,iii) +2b(ii,iii), this species is considered Critically Endangered (CR) based on its limited distribution (AOO, 8 km 2; EOO, not measurable) and the continuing decline in the quality of its habitats.   Selected specimens examined.  BRAZIL.  Goiás: Alto Paraíso de Goiás, Rod.
