Vegetative characteristics

side of a lower leaf with bristle hairs sitting on star-shaped, hairy humps and simple hairs in between (detail).

Onosma pseudoarenaria is a biennial herbaceous plant that reaches heights of up to 80 centimeters. The strong and well-branched stems are fine and hairy with protruding 2 to 3 millimeter bristles.

The lower leaves are 80 to 200 millimeters long and 8 to 13 millimeters wide, linearly elongated and not fine, but densely haired with 1.5 to 2 millimeter long bristles, at least some of which are star-shaped and 0.1 to 0.2 millimeters have long rays.

Generative characteristics

The inflorescences are branched. The flower stalks are 0 to 2 millimeters long. The bracts are shorter than the calyx .

The hermaphrodite flowers are five-fold with a double flower envelope . The calyx is 8 to 10 millimeters long at the anthesis , enlarges on the fruit to up to 16 millimeters. Usually the crown is about 1 1/3 to 1 1/2 times as long as the calyx. The crown is 12 to 16 millimeters long, pale yellow and hairless or sparsely finely haired.

The nuts are 2.5 to 3 millimeters long, smooth and shiny.
