This photograph was taken only a few steps away from this Populus tremuloides in June.

Distributed throughout western North America, the specific epithet (formosa) for red or western columbine means “beautiful”. Apt.

According to Parish, Coupé and Lloyd in Plants of Southern Interior British Columbia, the word columbine is a derivation of the Latin columbina, meaning “dove-like” (Columbina passerina is the scientific name for the common ground-dove). Parish et al. write: “The arched petals and spurs of the flowers resemble a quintet of doves arranged in a ring around a dish (a favourite device of ancient artists).” I can see the resemblance, but I don't think I would have imagined it on my own.

As an aside, please note that if you come across the epithets formosana or formosanum, they have a different and unrelated meaning: of Formosa, or, using the modern name for that island, of Taiwan.
