Piper nigrum (ගම්මිරිස්)
Black pepper (Piper nigrum) is a flowering vine in the family Piperaceae, cultivated for its fruit, known as a peppercorn, which is usually dried and used as a spice and seasoning. The fruit is drupe (stonefruit) which, when fresh and fully mature, is about 5 mm in diameter, dark red, and contains a stone which encloses a single pepper seed. Peppercorns and the ground pepper derived from them may be described simply as pepper, or more precisely as black pepper (cooked and dried unripe fruit), green pepper (dried unripe fruit), or white pepper (ripe fruit seeds).
Piper nigrum is part of the catalog of ayurvedic medicinal plants of Sri Lanka.
