Leaf: 0.3–8 cm, ovate to obovate, strong-veined abaxially, glabrous to hairy, occasionally glandular, teeth entire to compound; base truncate to wedge-shaped; petiole distinct or not. Inflorescence: 2–25 cm, 1.5–25 cm wide. Flower: hypanthium 3–5 mm wide; sepals 1–2 mm; petals 1.5–2 mm; style 1 mm. Fruit: achenes 1–1.5 mm, often with sessile glands. [Holodiscus saxicola A.
