Scutellaria Platyphylla, Mexican Skullcap

Scutellaria platyphylla plants have several to many stems, upright or ascending, a little over one foot tall. All parts of the stems and leaves are covered by stalked glandular hairs, greyish white in color. The bright green leaves are obtuse at the tip, tapering at the base, with slightly undulating margins. Hairs are longer on the undersurfaces.

One to three flowers form at the upper leaf axils. They have a short, green, two-lipped calyx, hairy and glandular, and a violet-blue corolla, hairy on the outside. The corolla has two lips; the upper is larger and hood-like, projecting forwards, while the lower is lobed, bent downwards, and grooved down the middle, with two broad white bands down each side, sometimes flecked with purple. Inside the corolla are four stamens with ciliate anthers.
