About Maxillaria speciosa Rchb.f.
Maxillaria speciosa Rchb.f. is either epiphytic or lithophytic, growing from a pseudobulb that is anchored on rocks or other plants. Its flowers are large, fragrant, and spider-like, with narrow, spreading sepals that measure 12–15 cm in length. The labellum is 3-lobed, with an obtuse, elliptical midlobe. The flowers display a combination of yellow, white, and brown coloring: sepals and petals are white near their base and yellow near their apices, marked with dark purple spots. The lip has a similar color pattern, with a midlobe that ranges from white to yellow. This species is endemic to the Chocó–Darién moist forests of Colombia and Ecuador. This region consists of wet, tropical, montane rainforests that are known for their high orchid biodiversity. One study site for this species in Ecuador, located at an elevation of 640 m, experiences at least 190 wet days per year, and has a mean annual precipitation of 1393 mm.
