Oblongleaf false pennyroyal
Arizona and New Mexico
Open woodland, hillsides, from 3,000 to 8,500 feet
Oblong, opposite, hairy, up to 0.6 inches long and 0.3 inches wide
Stems and leaves of hedeoma oblongifolia have a covering of short, curled or crisped hairs, white or greyish. Plants produce several stems, which branch from the base, and are held vertically upwards or at a slight angle. Leaves are attached by short stalks, and may be lined by a few shallow, well-separated teeth.
Flowers form in whorls at the leaf nodes, of two to four, at the end of short, hairy pedicels. Calyces are green, ribbed, hairy, divided just below the tip into five triangular teeth (three slightly longer than the other two), while the corollas are pink to purple with white patches, narrowly funnel-shaped, and opening to a three-lobed lower lip and a cupped, unlobed upper lip. The corolla tube is a little longer than the calyx. The corolla has a covering of very short hairs on the outside; the inside is glabrous. Stamens are exserted; they have pale pink filaments and purple anthers.
