All nine species in this section are found in cool forest habitats with eight in southeastern Brazil, from Minas Gerais to Rio Grande do Sul, and one, F. magellanica, occurring from the Andes and coastal slopes of southern Chile and Argentina between thirty-three and fifty-five degrees south latitude (Berry 1989). These shrubs or lianas have opposite or whorled leaves. The pendulous, or rarely divergent, flowers are axillary, solitary or rarely in pairs with a floral tube 3 to 15 mm long, and have smooth or weakly lobed, band-type nectaries. The sepals are longer than the floral tube, partly connate and colored red. The petals are convolute and blue-violet. The stamens occur in two unequal series and are strongly exserted. They have yellow pollen. The seed count is between 60 and 120.
This section is named after Queluz Palace, the summer residence of the former Kings of Portugal, located in Queluz near Lisbon. Domenico Vandelli, first applied Quelusia to a Brazilian fuchsia, listed without a specific epithet but probably Fuchsia coccinea, provided to him by Joaquim Veloso de Miranda. José Mariano de Conceição Veloso also used Quelusia regia in his Florae Fluminensis (1825–27). The name was synonymized with Fuchsia but later revived by the Swiss botanist Augustin Pyramus de Candolle (1778 -1841) for one of the two sections into which he divided the genus in 1828.
