Flowers are borne on short flower-cluster-stalks, few or solitary in leaf axils, stalkless. Bracts are linear-thread-like, 6-8 mm. Leaves are overlapping at least above, kidney-shaped to round, 5-8 x 10-15 mm, rounded toothed, flat or broad wedge-shaped, white eglandular woolly on both surfaces; venation often purplish; leaf-stalk on lower leaves up to 1 cm, less above.
