Arizona and southwest New Mexico
Moist canyons and pine woodland, from 5,000 to 9,000 feet
Opposite, broadly lanceolate, stalked, lined by coarse teeth
Scrophularia parviflora grows in Arizona, from the northwest to the southeast, and in southwestern New Mexico. Leaves are in opposite pairs, attached by grooved petioles; they have a prominently-veined surface and the edges are lined by coarse teeth. Petioles are around a third as long as the leaf blades. Stems are square in cross-section, and have a fine covering of tiny hairs.
Flowers are arranged in an open, branched cluster, and are attached by glandular pedicels. The hairless calyces are divided into five lobes, pressed against the corolla, for which the two-lobed upper lip is dark brownish-red in color, while the three-lobed lower lip is mostly green. The middle lobe is recurved while the lateral lobes are angled forwards.
