Cattleya cernua this species grows best when mounted, in warm and bright conditions. 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
Flowering plant The APG system of 1998, and the later 2003 and 2009 revisions, treat the flowering plants as a clade called angiosperms without a formal botanical name. However, a formal classification was published alongside the 2009 revision in which the flowering plants form the Subclass Magnoliidae. The internal classification of this group has undergone considerable revision. The Cronquist system, proposed by Arthur Cronquist in 1968 and published in its full form in 1981, is still widely used but is no longer believed to accurately reflect phylogeny. A consensus about how the flowering plants should be arranged has recently begun to emerge
