Cattleya cernua Cattleya cernua Cattleya cernua, commonly known as the Nodding Sophronitis, is a species of orchid occurring from Brazil to northeastern Argentina. It was the type species of the genus "Sophronitis" until the genus was made synonymous with "Cattleya". Twenty plants of "C. cernua" have received a total of 22 AOS awards. The described flowers range from 1.9 cm to 3.2 cm horizontal spread and from 2.0 cm to 3.0 cm vertical spread. In nature, "Cattleya cernua" is pollinated by hummingbirds drawn to the blooms' warm colors. The orchid's cryptic pollinia (masses of pollen which adhere together) provide an interesting adaptation
Cattleya labiata plant has a pseudobulb under every leaf to store water and nutritive substances during the short dry season. In the wet season new leaves grow rapidly, producing a large flowered inflorescence. Flowers are white or lavender colored with a darker spot in the lip. Pollination is performed by insects, usually by a scent-collecting male euglossine bee. The result is a capsule with a very large number of seeds (10,000-20,000). The diploid chromosome number of "C. labiata" has been variously determined as 2"n" = 40, 41, and 46. The haploid chromosome number of "C. labiata" has been variously determined as "n"
