Cattleya walkeriana 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- or few-flowered, about 8" (20 cm) tall. Flowers are 4-5" (9-12 cm) across. Genetically "C. walkeriana" is close to bifoliate Cattleyas. The diploid chromosome number of "C.
Portia labiata stands his ground and she does not ran away or repeat the propulsive display, he approaches and, if she is mature, they copulate. If the female is sub-adult (one moult from maturity), a male may cohabit in the female's capture web. "Portia"s usually mate on a web or on a dragline made by the female. "P. labiata" typically copulates for about 100 seconds, while other genera can take several minutes or even several hours. Females of "P. labiata" and "P. schultzi" try to kill and eat their mates during or after copulation, by twisting and lunging. The males wait until
