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 4 millimetres below a leaf. The spider lies head down, and often slides down 20 to 30 millimetres during moulting. "Portia"s spin a similar temporary web for resting. "P. labiata" is found in Sri Lanka, India, southern China, Burma (Myanmar), Malaysia, Singapore, Java, Sumatra and the Philippines. The populations of "P. labiata" in Los Baños and in Sagada, both in the Philippines, have different environments: Los Baños is a low-lying tropical rainforest where there are many species of spiders, some of which are especially dangerous to "P. labiata"; and Sagada is at higher altitude, with pine-forest and fewer species of
