Atrosanguineus
/at-roh-san-GWIN-ee-us/🏷️ Taxonomy●●● Advanced
Also known as: atrosanguinea, atrosanguineum
A color epithet combining ater (dark, black) with sanguineus (blood-red) to describe a near-black, very deep blood-red — one of the darkest of all botanical color terms. It implies a color so saturated it appears almost black in shadow. Appears as atrosanguineus (masculine), atrosanguinea (feminine), or atrosanguineum (neuter).
Etymology
From Latin ater (dark, black) + sanguineus (blood-red, from sanguis, blood), meaning "darkly blood-red."
Example
“Cosmos atrosanguineus (chocolate cosmos) has flowers of such deep, blackish blood-red they are nearly black — a tone the epithet captures precisely and that gives the plant its extraordinary, almost edible, chocolate visual richness.”
