Pectinatus
/pek-tih-NAH-tus/🏷️ Taxonomy●●● Advanced
Also known as: pectinata, pectinatum
A leaf shape epithet for a blade or frond cut into many narrow, parallel segments set evenly along an axis, like the teeth of a comb. The regularity of that spacing is what separates it from merely dissected foliage. Appears as pectinatus (masculine), pectinata (feminine), or pectinatum (neuter).
Etymology
From Latin pectinatus, meaning "comb-like," from pecten/pectinis (comb).
Example
“Foliage described as pectinatus reads at a glance as a row of even teeth along a central rib.”
