Papilionanthe biswasiana is a species of epiphytic orchid native to Laos, China, Myanmar, and Thailand. It is closely related to Papilionanthe vandarum.
Description
It is erect or pendulous, slender, 50 cm (20 in) long, 13 to 16 mm (0.51 to 0.63 in) wide, usually unbranched stems with internodes of 3 to 4 cm (1.2 to 1.6 in) in length. It bears distichously arranged, terete leaves. They are 13 to 16 cm (5.1 to 6.3 in) long and 3 to 4 mm wide and fleshy. Stomata are presented on the entire leaf surface. Most stoma were brachyparacytic and laterocytic, but some were stephanocytic. The inflorescences, which usually do not exceed the length of the leaves, produce 1 to 3 widely opening, creamy white or slightly pink, large and thinly textured flowers in spring.
