5. Orthophytum subg. Capixabanthus Leme, S. Heller & Zizka (2017: 70)
Orthophytum subg. Capixabanthus can be distinguished from subg. Orthophytum by its distinctly caulescent habit with sessile inflorescence and obtuse-cucullate petals, or if the plants are stemless with pedunculate inflorescence, and the petals not obtuse-cucullate, then the petals bearing cupuliform to sacciform appendages, pollen comparatively smaller with reticulum formed by broad and flat muri with lumina or foveolae decreasing in size significantly towards the sulcus margins, especially towards the apices, and the exine becoming almost psilate. In some species the sepals are unequal or nearly so, with the alate-carinate adaxial ones exceeding the ecarinate abaxial one, which is not observed in any other subgenera. Its geographical distribution is concentrated in Atlantic Forest related habitats in the centralnorthwestern region of Espírito Santo state and in neighboring areas in Minas Gerais and Bahia states, currently comprising eight species, including the new species proposed below.
