stipellate

A small leaf near the base of the leaf stalk is stipellate.

Definition
  1. Adjective:
    • Botany: "Stipellate" describes a plant structure that possesses small, secondary stipules (called stipels). Stipels are tiny, leaf-like appendages found at the base of leaflets in compound leaves, often subtending the leaflets themselves.
Usage Examples
  • (The plant has small, secondary stipules on its compound leaves.)
  • (The plant is identified by having these small structures.)
Advanced Usage
  • "Stipellate leaf": a compound leaf that bears stipels.
    • A stipellate leaf is common in the Fabaceae family, such as in beans and peas. (The leaf has small, scale-like outgrowths at the base of its leaflets.)
  • "Stipellate condition": the state of having stipels.
    • The stipellate condition is a key taxonomic feature for distinguishing certain plant genera. (The presence of stipels helps identify plant groups.)
Variants and Related Words
  • Stipule (n): a small, leaf-like structure at the base of a leaf or leaf stalk.
    • The stipule protects the developing leaf bud. (A similar but larger structure than a stipel.)
  • Stipel (n): a small, secondary stipule on a leaflet or leaflet stalk.
    • Each leaflet in this compound leaf has a tiny stipel at its base. (The specific structure that "stipellate" refers to.)
  • Exstipellate (adj): lacking stipels.
    • In contrast, the exstipellate leaves of this species have no such appendages. (The opposite of stipellate.)
Synonyms
  • Stipuled: having stipules (though this is a broader term; "stipellate" is more specific to small, secondary stipules on leaflets).
    • The plant is stipuled at the main leaf base, but it is not stipellate on the leaflets. (A related but not identical term.)
