Piper retrofractum, the Balinese long pepper or Javanese long pepper, is a flowering vine in the family Piperaceae, cultivated for its fruit, which is usually dried and used as a spice and seasoning. The fruit of Piper retrofractum is similar in appearance and taste to that of the Indian long pepper (P. longum). In Cambodia, it is known as ដីប្លី (Dei-Phlei) and, in Thailand as ดีปลี (Dee'bPlee). This plant is a climbing vine with stems of about 3–4 mm in diameter. Its leaves have blades that are glabrous, lanceolate, with acuminate apex and asymmetric base, and are about 10–12 cm long and 3–3.5 cm wide. The vine is dioecious, with male spikes of about 5 cm long and female spikes about 4 cm long and 0.5–1 cm wide, and part of the ovaries are attached on the axis. Its berries are spherical and arranged densely on the axis.
