Articulatus
/ar-tik-yoo-LAH-tus/🏷️ Taxonomy●● Intermediate
Also known as: articulata, articulatum
A morphological epithet describing a plant body that is clearly divided into distinct segments at visible joints — like the segments of a bamboo cane or the sections of a horsetail stem. The joints may be constrictions, swellings, or simple colour boundaries. Appears as articulatus (masculine), articulata (feminine), or articulatum (neuter).
Etymology
From Latin articulatus, past participle of articulare (to divide into joints), from articulus (a joint, knuckle), diminutive of artus (joint).
Example
“Juncus articulatus (jointed rush) and Equisetum (horsetail), whose entire stem structure is defined by its articulated segments, both illustrate the clearly segmented, jointed structure this epithet records.”
