Definition
  1. Adjective (Botany):
    • Having overlapping edges: "obvolute" describes a type of arrangement in which one leaf or petal is folded inward and overlaps the edge of another, typically in a bud or young shoot. This is a specific botanical term for a form of vernation (the arrangement of leaves in a bud).

    • The leaves of this plant are obvolute, with each leaf margin partially covering the next. (A botanical description of leaf arrangement in a bud.)
    • In obvolute vernation, the edges of the leaves are folded and overlapping. (A precise botanical term for a specific growth pattern.)
Advanced Usage
  • "obvolute vernation": a specific type of leaf arrangement in a bud where one leaf is folded inward and overlaps the edge of the adjacent leaf.

    • The obvolute vernation of the fern fronds helps protect the delicate developing tissues. (The overlapping leaf arrangement provides protection.)
  • "obvolute corolla": a flower structure where petals or sepals are arranged in an overlapping, folded manner.

    • The obvolute corolla of the morning glory is a classic example of this botanical feature. (The flower's petal arrangement is obvolute.)

Additional Notes
  • Context: "Obvolute" is almost exclusively used in botany, particularly in descriptions of leaf or flower bud arrangement. It is not used in everyday language.
  • Opposite term: "Convolute" refers to a leaf or petal that is rolled inward spirally, rather than folded and overlapping in a flat manner.
