The Genus Brassavola, (L.) R.Br
The Genus Brassavola, (L.) R.Br. in W.T.Aiton, Hortus Kew. 5: 216 (1813) Type: Brassavola [B.] cucullata [bra-SAH-vo-la kyoo-kyoo-LAH-ta] There are 28 species (OrchidWiz [update Dec 2017]) that are epiphytes and sometimes lithophytes at elevations of from sea level to 3300 ft (1000 m) from Mexico, southern Caribbean islands to northern Argentina in moist or wet montane forests, mangroves, rocky crevices and cliff faces. They are most fragrant at night and many with a citrus smell. The genus is characterized by very small pencil-like pseudobulbs, often forming large clumps; a single, fleshy, apical, sub-terete leaf and the inflorescence produced form the apex of the pseudobulb. The inflorescence carries from a single to a few large flowers. The floral characteristics are elongate narrow similar sepals and petals, the base of the lip usually tightly rolled around at least a portion of the column which carries 12, sometimes eight unequal pollina with prominent opaque caudicles. The flowers usually occur, as a rule, in spring, summer and fall. The flowers are generally yellow to greenish white with a mostly white lip. It is not unusual for dark spots, usually purple, to be in the region where the sepals, petals, and lip join the stem (claw). This spotting is a dominant generic trait in Brassavola nodose. They are easily cultivated under intermediate conditions. Although this is a relatively small genus (28 species), the species show an unusually close relationship with one another in their floral patterns, coloration, and column structure making identification difficult, key to know where the plants were collected.
