英和和英

語源 1

Learned borrowing from Latin palmātus (“hand-shaped, palm-leaf shaped”), from palma (“palm, palm-tree”). Equivalent to palm +‎ -ate (adjective-forming suffix). Compare French palmé.

形容詞

palmate (not comparable)

1. (chiefly botany) Having three or more lobes or veins arising from a common point.

   Although palmate leaves are typical of most Western maples, a number of species have leaves without lobes.

2. (botany, of leaves) Having more than three leaflets arising from a common point, often in the form of a fan.
   • 1909, Eleanor Stockhouse Atkinson, “In the Tree Tops”, in The How and Why Library:

     The horse chestnut, buckeye and hickory trees have palmate leaves. That is, the broad oval leaflets are all set around the tip of a common leaf stem, spreading in a circle, like the ribs of a palm leaf fan.

3. (rare) Having webbed appendage; palmated.

   The Palmate Newt is a common Western European amphibian.

4. (rare) Hand-like; shaped like a hand with extended fingers

使用する際の注意点

• The word is rare outside of technical writing, and hardly ever qualifies things other than leaves.
• A compound leaf with more than three leaflets (trifoliate) radiating from the same point is more usually called palmate or palmately compound to avoid ambiguity.
• While "palmated" is a more usual term when referring to webbed appendages, "palmate" is often found in zoological nomenclature as the Latin term for both meanings is palmatus.
