Epiphytic herb with cylindric or spindle-shaped pseudobulbs, up to 35 cm. high, with one leaf at the top. Leaf oblong or elliptic-oblong, obtuse, light green, up to 35 cm. long and up to 6 cm. wide, coriaceous. Inflorescence up to 20.3 cm. high, with 3 to 6 (or 10) flowers. Flowers large and showy, up to 17 cm wide, with sepals and petals being cream-colored or ivory white, except the lip or labellum, which is colored with yellow,
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"
