A rough or bristly plant part, or a bristle-like structure found on certain plants and animals, particularly used in botanical descriptions.
Possibly from Italian or Spanish diminutive forms related to 'brush,' though the exact etymology is disputed among linguists. It appears in specialized botanical literature with varying definitions.
Some technical terms in botany exist in multiple languages with slight variations because early naturalists learned from each other across borders—'bruscha' shows how plant descriptions are partially international inventions.
