Condea is a genus of aromatic flowering plants in the mint family, Lamiaceae, order Lamiales. The genus comprises roughly 27 described species, with approximately 9 accepted under current circumscription, distributed across the Americas from the Caribbean and Central America to the deserts of the southwestern United States and northwestern Mexico.
Plants in Condea are typically shrubs or subshrubs with aromatic foliage characteristic of the Lamiaceae. The best-known member, Condea emoryi (desert lavender), is a large multi-stemmed perennial shrub growing 8–12 ft tall in favorable conditions, bearing violet-blue flowers in leaf axils and oval, gray-green, hairy leaves with serrated margins. It is found in dry washes and rocky slopes of the Sonoran and Mojave deserts, and is a notable early-spring nectar source for honeybees.
The genus was reinstated after phylogenetic studies using nuclear and plastid DNA demonstrated that the former broad genus Hyptis was polyphyletic. Several species previously placed in Hyptis — including Hyptis emoryi — were transferred to Condea, which was originally described by Adanson in 1763. Condea and Hyptis both remain in Lamiaceae but now represent separate, more natural groupings.
Distribution
Condea species occur across the Americas, with centers of diversity in the Caribbean and Central America. Condea emoryi, the most range-documented species, is native to the southwestern United States (Arizona, Nevada, California) and northwestern Mexico (Sonora, Baja California), growing in the Sonoran and Mojave desert regions, typically in dry washes and on rocky slopes below 1000 m elevation.
Ecology
Condea emoryi and likely related species occupy xeric scrub habitats, growing in dry washes and rocky desert slopes within the creosote bush scrub community alongside palo verde, desert ironwood (Olneya tesota), brittlebush (Encelia farinosa), and Acacia greggii. The aromatic flowers attract honeybees and other pollinators, and the species is noted as a particularly valuable early-spring forage plant for bees in the southwest deserts of North America.
Taxonomy Notes
Condea was originally described by Adanson in 1763 but was long subsumed within the broader genus Hyptis. Molecular phylogenetic analyses based on nuclear and plastid DNA revealed that Hyptis as traditionally circumscribed was polyphyletic, leading to its breakup and the reinstatement of Condea as a distinct genus. Species previously placed in Hyptis — such as Hyptis emoryi, now Condea emoryi — were formally transferred to Condea.
