    • n trichostema A genus of gamopetalous plants, of the order Labiatæ and tribe Ajugoideæ. It is characterized by the four long-exserted stamens with divaricate anthercells, and by the deeply lobed ovary. The 8 species are all natives of North America. They are clammy glandular herbs with a strong balsamic odor. They bear entire leaves, and axillary whorls of numerous mostly blue flowers, the corolla with a slender tube and nearly equally five-toothed spreading border, from which the conspicuous arching stamens project, suggesting the popnlar name blue-curls (which see). The species of the eastern United States have a very strongly two-lipped and depressed calyx, and loose flower-clusters, as T. dichotomum, the bastard pennyroyal. The western have the calyx normal and the flower-clusters dense. T. lanatum, with a striking purplewoolly spike, is known in California as black sage.
