Definition
Meaning
A highly poisonous plant (Abrus precatorius) producing small, red-and-black seeds often used in jewellery and rosaries.
The specific seeds of this plant, which are attractive but lethally toxic if the seed coat is broken. Metaphorically, can refer to something alluring yet dangerous.
Linguistics
Semantic Notes
Primarily a botanical term for a specific toxic plant species. The term is often used metonymically to refer to its seeds. In everyday language, it may be known simply by its genus 'Abrus' or the folk name 'jequirity bean'.
Dialectal Variation

Connotations
Neutral in both, strictly referential to the plant/seed. No regional connotative difference.
Frequency

FAQ
Frequently Asked Questions
No. Despite the name, it is not related to edible garden peas. It is a legume in the Fabaceae family but is highly toxic and not for consumption.
The intact seeds with an unbroken coat are generally safe to handle briefly. The extreme danger comes from ingestion, inhalation, or injection of the crushed seed's contents, which contain the toxin abrin.
Because its hard, brightly coloured seeds (typically red with a black spot) have historically been used to make beads for jewellery and prayer rosaries, particularly in some cultures, after being properly treated to mitigate risk.
Seek immediate emergency medical attention. There is no antidote, and treatment is supportive. Do not induce vomiting unless instructed by a medical professional.
