High Quality Content by WIKIPEDIA articles! Bast fibre or skin fibre is plant fibre collected from the phloem (the "inner bark" or the skin) or bast surrounding the stem of certain, mainly dicotyledonic, plants. They support the conductive cells of the phloem and provide strength to the stem. Most of the technically important bast fibres are obtained from herbs cultivated in agriculture, as for instance flax, hemp, or ramie, but also bast fibres from wild plants, as stinging nettle, and trees such as the Tilia, have been used to some extent. Since the valuable fibres are located in the phloem, they must often be separated from the xylem material ("woody core"), and sometimes also from epidermis.
