Species names (incl. publication and synonyms): See Skog, L.E. & J.K. Boggan. 2005: World checklist of Gesneriaceae: http://persoon.si.edu/Gesneriaceae/Checklist.
Type species: Mandirola multiflora (Gardn.) Decne.
Ecology: No details known.
Notes: Based on molecular evidence, Mandirola was recently re-established to include three species from Brazil formerly placed in Gloxinia: G. ichthyostoma, G. multiflora, and G. rupestris (Roalson et al. 2005a,b, Boggan 2006). The species are very similar to Achimenes, and were once included in that genus. The genus is more closely related to Goyazia than to Gloxinia or Achimenes. From the three species, only the first is in cultivation.
