Hyptis is a genus of approximately 170 species of flowering plants in the family Lamiaceae (the mint family), order Lamiales. Commonly known as bushmints, these plants are native to the subtropical and tropical Americas, ranging from the southern United States south to northern Argentina. Members of the genus exhibit a wide diversity of growth forms, from annual and perennial herbs to subshrubs and shrubs. A diagnostic feature of the genus is the deflexed lower lip of the corolla — the trait that gave the genus its name, from the Greek hyptios (ὕπτιος), meaning "supine" or "lying on one's back." Inflorescences are compound and may be lax or congested, frequently bearing involucral bracts. Plants typically grow in tropical or subtropical savanna habitats.
The genus was first described by Nicolaus Jacquin in 1786, and further organized into morphological sections by George Bentham in 1832. Subsequent decades brought repeated rearrangements; by 2004 the genus encompassed 285 species across 24 sections. Molecular phylogenetic work in 2011, using nuclear and plastid DNA, revealed that the genus as then conceived was paraphyletic. A major revision by Harley and Pastore in 2012 reduced the sections from 24 to 10 and segregated several groups into new or reinstated genera — including Cantinoa, Mesosphaerum, and Oocephalus — bringing the total closer to 144 species and rendering the remaining genus monophyletic. A 2021 follow-up study by Pastore further supported monophyly. The most recently described species, Hyptis raymondii, was published in 2025 and named in honor of botanist Raymond Harley for his contributions to the genus and the broader Lamiaceae family. The genus currently comprises 170 accepted species.
Etymology
The genus name Hyptis derives from the ancient Greek word hyptios (ὕπτιος), meaning "supine" or "lying on one's back." The name alludes to the distinctive deflexed lower lip of the corolla, which appears to recline away from the rest of the flower.
Distribution
Bushmints are native to the subtropical and tropical Americas, distributed from the southern United States south to northern Argentina. They are most diverse in tropical and subtropical savanna habitats but occur across a range of open and semi-open environments throughout Central and South America.
Taxonomy Notes
The genus was first described by Nicolaus Jacquin in 1786. George Bentham revised it in 1832, organizing species into sections based on inflorescence morphology. By 2004, Hyptis encompassed 285 species across 24 sections. Molecular phylogenetic studies in 2011 demonstrated the genus was paraphyletic, prompting Harley and Pastore's 2012 revision, which reduced sections to 10 and erected new segregate genera (Cantinoa, Mesosphaerum, Oocephalus), leaving a monophyletic Hyptis of about 144 species. A 2021 study by Pastore confirmed the current circumscription. The newest species, Hyptis raymondii, was described in 2025; the genus now stands at 170 accepted species.
