Duration: Perennial Nativity: Native Lifeform: Forb/Herb General: Herbaceous, acaulescent perennials, stems scapose, to 40 cm, branching from the woody, scaly caudex, herbage stipitate-glandular, plants arising from scaly rhizomes. Leaves: Mostly basal, orbicular to broadly ovate, 2.5-9 cm, shallowly 5-10 lobed, margins dentate, bases cordate, the blades palmately veined and with long, finely puberulent petioles, purple below, dusty green and somewhat variegated above. Flowers: Greenish to yellowish, campanulate, stipitate-glandular, 3-5 mm long with 5 whitish petals, these small, entire, clawed, shorter than the sepals and not much wider than the claw, copiously white-hirsute and puberulent, sepals oblong or ovate, 1.5-2 mm, erect to incurved at the tip, stamens 5, included, shorter than and opposite the sepal lobes, styles 2 with a well-developed turbinate or campanulate hypanthium, flowers borne in dense, interrupted, elongate and contracted panicles, the lower branches usually less than 2 cm long. Fruits: Ovoid capsule 4-5 mm, with 2 divergent beaks. Seeds black, fusiform, to 0.5 mm, numerous. Ecology: Found on shaded, rocky slopes in mountainous areas, from 4,000-9,000 ft (1219- 2743 m); flowering May-August. Distribution: Arizona, New Mexico. Ethnobotany: There is no specific use recorded for the species, but the genus has many uses. Etymology: Heuchera is named after Johann Heinrich von Heucher (1677-1747), professor of medicine and botanist at Wittenberg, Germany, while glomerulata means clustered.
