Discussion

Flowers of Geum glaciale have from five to nine petals with seven being the most common. Other species of Geum nearly always have five petals, which is standard in most rosaceous genera. The sepals of G. glaciale are usually in two whorls for a total of about ten, and the bractlets are in two to three whorls. The exact number of epicalyx bractlets and sepals is made difficult to determine by the thick covering of hairs and because individual sepals and bractlets are sometimes deeply divided into two equal lobes.
