About Trichostema gracile K.S.McClell., 2023
Trichostema gracile, a scientifically described species of the mint family, is an aromatic herbaceous plant. Like other members of this family, it has opposite leaves and square stems. Its floral structure matches the standard characteristics of the genus Trichostema, with bilaterally symmetrical flowers and stamens that extend beyond the petals. This species can be distinguished from its close relatives by specific details of leaf size and shape, and also by unique features of its calyx and inflorescence, which are fully detailed in the original species description. This species is endemic to Florida, where it grows in habitats ranging from mesic flatwoods to scrubby flatwoods. Its currently known distribution is geographically restricted, which is attributed to both its specialized habitat requirements and the fact that it was only recently recognized as a distinct taxon.
