Etymology
The word 'astragalus' has a direct lineage from ancient Greek, where 'astragalos' referred specifically to the anklebone (talus) used as a die in games. This term was adopted into Latin as 'astragalus' with the same anatomical meaning. In botanical taxonomy, the Swedish naturalist Carl Linnaeus applied the name in the 18th century to a genus of plants, likely due to the jointed, knobbly appearance of the seed pods or roots, which visually recalled the shape of the anklebone. Thus, the term's journey connects a literal bone from antiquity to both a modern anatomical term and a metaphorical descriptor in plant morphology.
