Cattleya walkeriana walkeriana" has been twice determined as 2"n" = 40; the diploid chromosome number of the variety "C. walkeriana" var. "princeps" has been determined as 2"n" = 80. Cattleya walkeriana Cattleya walkeriana (Walker's cattleya) is a species of orchid. It differs from most species of "Cattleya" by having inflorescences which arise from the rhizome instead of from the apex of the pseudobulb. In its native habitat (Brazilian Central Plateau) it grows as either an epiphyte or a lithophyte, sometimes in full sun. Pseudobulbs are relatively short, bulbous or fusiform, with one or two ovate leaves at the apex. Inflorescence is one-
Portia labiata webs to deceive the prey and detouring for a stab in the back. A test in 2001 showed that four jumping species take nectar, either by sucking it from the surface of flowers or biting the flowers with their fangs. The spiders fed in cycles of two to four minutes, then groomed, especially their chelicerae, before another cycle. A more formal part of the test showed that 90 juvenile jumping spiders, including "P. labiata", generally prefer to suck from blotting soaked with a 30% solution of sugar in water rather than paper soaked with pure water. The authors suggest that,
