Murici Ecological Station an average of . The dominant vegetation is dense rainforest in the Atlantic Forest biome. In the best preserved areas, mostly at the higher elevations, the forest forms a fairly uniform closed canopy up to high that provides shade and retains moisture. Tree species include murici ("Byrsonima sericea"), "Schefflera morototoni", "Parkia pendula", "Tabebuia" species, "Pseudobombax" species, "Bowdichia virgilioides", "Tapirira guianensis", "Handroanthus impetiginosus" and "Protium" species. The understory contains seedlings of trees, palms such as "Euterpe catinga", and many lianas and epiphytes, such as "Araceae", "Orchidaceae" ("dimerandra" species, "Dichaea" species, "Rodriguezia" species, "Cattleya labiata", "Pleurothallis" species, "Epidendrum" species, "Oncidium" species and
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
