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
Portia labiata spiders, none of which are as dangerous to "P. labiata". The Los Baños variant has a slightly wider repertoire of tactics. In the Philippines, "P. labiata" does not prey on ants, but is preyed on by the ants "Oecophylla smaragdina" and "Odontomachus" sp. (species uncertain), and a solitary "Odontomachus" has been seen attacking a "P. labiata". In a test the ant "Diacamma vagans" usually killed single-handed a "P. labiata". "P. labiata" is one of 17 species in the genus "Portia" as of May 2011. This species has been named "Sinis fimbriatus" (Hasselt, 1882; misidentification), "Linus labiatus" (Thorell, 1887), "Linus dentipalpis"
