Anatomical characters of diagnostic value in
Scutellaria agrestis were recorded in the present study, in
particular, the presence of an epithem hydathode, described
for the first time for the genus. Furthermore, ordinary
characters of the Lamiaceae family and the Scutellaria
genus were found, such as multicellular tector trichomes
and glands of the capitate and pelatate types, diacytic
stomata, numerous intercellular spaces, and a square stem
with evident endodermis. This information is important, as
it helps in the identification of the species and contributes
to its quality control, given that the plant in question is used for medicinal purposes.
