The present study was carried out to establish the pharmacognostical characters of stem of Tribulus terrestris L. No reports are available on the pharmacognostical studies of the stem; hence, the present study was carried out to help in identification of this plant for the future references. The microscopical studies of stem revealed the presence of cluster crystals, nonglandular hairs, starch granules, lignified fibers, pitted wood parenchyma, trachides and lignified spiral and pitted xylem vessels.
