Xylotomical features ofTournefortia rugosa, Tournefortia caracasana, Heliotropium angiospermum andMallotomia gnaphalodes of the family Boraginaceae have been described with emphasis on vessel elements, fibrous elements, parenchyma and vascular rays. Presence of helical thickenings in the narrow vessels, septate fibres, siliceous granules, crystals, tannins and druses in the ray cells are some of the interesting features met with in these members.
