Definition

Adjective: - Describing a leaf shape: A botanical term used to describe a leaf that is deeply divided into lobes, with the incisions (clefts) extending more than halfway toward the base or midrib, and the lobes are arranged in a palm-like (radiating) fashion from a central point. It is more deeply divided than "palmately lobed" but not so deeply as to separate into distinct leaflets (which would be "palmate").

Usage

• This term is used almost exclusively in botanical, horticultural, and scientific descriptions to classify and describe the morphology of leaves.
• It is a precise descriptor for the depth and pattern of division in a leaf blade.

Examples

• Adjective:
  • The leaves of the Japanese maple are often palmatifid, with deep, narrow clefts.
  • The botanist noted the plant's palmatifid foliage in her field notes.

Advanced Usage

• Comparative Description: The term is part of a spectrum for describing palmately divided leaves:
  • Palmately lobed: Incisions extend less than halfway to the base.
  • Palmatifid: Incisions extend more than halfway to the base.
  • Palmatisect: Incisions extend almost, but not quite, to the base.
  • Palmate (compound): Leaflets are fully separated, attached at a single point.

Variants and Related Words

• Palmate (adj): The broader category; describing any leaf with lobes, veins, or leaflets radiating from a central point like fingers from a palm.
• Palmatisect (adj): Describing a leaf palmately divided almost to the base into distinct but not fully separated segments.
• -fid (suffix): A botanical suffix meaning "divided into parts" or "cleft" (e.g., ).

Synonyms

• Deeply palmately cleft: A more descriptive, non-technical synonym.
• Palmately parted: A closely related botanical term sometimes used interchangeably, though "parted" often implies divisions reaching nearly to the base.

Antonyms

• Simple leaf: A leaf with an undivided blade.
• Entire leaf: A leaf with a smooth, uninterrupted margin.
• Palmately lobed: A leaf with shallower divisions.
