Field Characters

Skullcaps get their name from (and are recognized by) their crested calyx. This species differs from Scutellaria integrifolia by its flowers which are axillary and its upper leaves which are toothed. Three varieties: var. Leonardii - smooth or with minute hairs that are curled or appressed in the upper part of the plant. There is no sign of glands. var. parvula - stems with glandular and nonglandular hairs that are pointed backward. The lateral leaf veins do not rejoin after branching forming an intertwining network. var australis- stem with both short curved nonglandular hairs that point upward and glandular hairs on the angles. The lateral leaf veins rejoin after branching forming an intertwining network.
