penstemon
UK[penˈstiːmən]US[pɛnˈstimən]
n
Any of a large genus (Penstemon) of chiefly North American plants of the snapdragon family, having showy, tubular, two-lipped flowers.
Etymology
The word 'penstemon' is a scientific Latin creation, coined in the 18th century by botanist John Mitchell. It was constructed from two Ancient Greek words: 'pente' (πέντε), meaning 'five', and 'stēmōn' (στήμων), meaning 'warp' or 'thread', which in a botanical context refers to a stamen. The name was originally 'Pentstemon', reflecting the 'five stamens' characteristic of the flower, with four being fertile and one sterile stamen often appearing beard-like. Over time, the initial 'n' was assimilated, simplifying the spelling to 'penstemon', which now functions as an unanalyzable whole in modern English usage.
Analysis
This word is a modern Latin genus name, formed from two Greek elements that have been fused into a single, unsegmentable unit in its current English spelling.
