Cattleya granulosa

A tall bifoliate Cattleya from the hot coastal lowlands of north-eastern Brazil. Its waxy, spotted flowers have a lip covered in small raised granules, which gives the species its name. It is a warm-growing epiphyte that wants bright light, heat all year and a drier spell after flowering.

Where it grows wild

GBIF records cluster in the coastal strip from Rio Grande do Norte through Paraíba, Pernambuco and Alagoas to Bahia: restinga, dune and beach-margin vegetation (APA de Jenipabu, Praia de Zumbi) and coastal Atlantic forest remnants. One label notes it growing in shaded cacao plantations (cabruca). It grows as an epiphyte on trees in these bright, hot, breezy habitats. The larger southern plants from Espírito Santo and Rio de Janeiro are now usually treated as C. schofieldiana.

Wild GBIF records with an altitude are at 0–100 m; isolated labels at 700 m and 1643 m are probably georeferencing errors or cultivated plants.
