This is an herbaceous plant having an aromatic odor, with an erect and ramose stem, about 16 or 20 inches high; it is pubescent, quadrangular and grooved towards the upper branches. Leaves opposite, oval, finely indented, on petioles of the same length, as the limbs of the leaves. Flowers whorled, forming terminal spikes; each whorl is provided with two foliaceous bracts. Calix with five divisions, the upper being oval, large and entire; the other four are sharp and inferior. Corol tubulous, inverted, with a bilabiate limb; the upper lip divided into four lobes; the lower lip composed of a single lobe, which is longer. Stamens four, with free and outward-bent filaments, and two other stamens, which are shorter and somewhat geniculate at their base; style filiform and bifid. Root vertical, fibrous, rather ramose. We use the leaves. The ocimum canum is destined to become one of the most important remedial agents in Brazil, where it is used as a specific for the diseases of the kidneys, bladder and urethra.
