Satyrium humile spurs prominent

In this Satyrium humile flower spike one sees the white spurs with coloured tips veering away from the ovary below each flower. The pair of spurs are longer than the green, grooved ovary between them. The spurs are filled with nectar of a spicy jasmine scent. Moths probably pollinate these flowers.

The tongue-like median or odd sepal pointing down below each flower is long, as are the two lateral sepals, oblong in shape with acute tips. A notable erect fringe can be seen on the rim of the hood at the top of the flower. The column is curved, the stigma oblong. The rostellum is oval to spoon-shaped and somewhat concave, 1 mm long, about half as long as the stigma (Liltved and Johnson, 2012; JSTOR).
