Pinalia polyura

Pinalia polyura, or many-tailed pinalia, is a member of the orchid family endemic to the Philippines. It is semi-pendulous and sympodial, with pseudobulbs that are 20 cm long, 1 cm in diameter, and somewhat club shaped.^[2] Each new growth begins halfway along the previous year's pseudobulbs, making the plant longer each year. Each pseudobulb has about 5 shiny, lanceolate leaves approximately 15 cm long and 2 cm wide. Inflorescences appear at the upper portion of the plant and are pendulous, about 10 cm long and bear up to 40 flowers each 1.5 cm in diameter. It grows as an epiphyte and sometimes as a semi-terrestrial plant at elevations to 2,400 meters.^[3]
