Derivation of the botanical name:
Epilobium from the Byzantine Greek word epi, ἐπί, "upon", lobos, λοβός, λόβος "lobe", "a pod or capsule," as the flower and capsule appear together, the corolla being borne on the end of the ovary.
angustifolium, angustus "narrow", i, connective vowel used by botanical Latin, folium, "leaf"; narrow leaf.
Chamaenerion, Greek chamai, on the ground, lowly, creeping, dwarf; nerion, oleander; dwarf oleander.
Chamerion has replaced the invalid name Chamaenerion published by Seguier in 1754.
