Sulcatus
/sul-KAH-tus/🏷️ Taxonomy●● Intermediate
Also known as: sulcata, sulcatum
A morphological epithet describing a surface marked with parallel grooves or furrows running lengthwise — like furrows in a ploughed field. Furrowed stems, roots, or fruit surfaces are a useful identification feature. Appears as sulcatus (masculine), sulcata (feminine), or sulcatum (neuter).
Etymology
From Latin sulcatus, past participle of sulcare (to furrow, to plough), from sulcus (a furrow, groove, rut).
Example
“Euphorbia sulcata and Carex sulcata both have the characteristically deeply grooved, furrowed surfaces the epithet describes — ridges running the length of the stem that are immediately detectable by touch.”
