Shrubs, subshrubs, or herbs, perennial (Aruncus); unarmed. Leaves alternate, simple or pinnately compound; stipules absent; venation pinnate, sometimes palmate. Flowers: perianth and androecium perigynous; epicalyx bractlets absent or present; hypanthium shallowly bowl-shaped, hemispheric, campanulate, patelliform, +/- crateriform, or turbinate; torus absent, minute, or thickened; carpels 3–5(or 6)[–8], distinct, free or adnate to hypanthium base, styles +/- terminal, distinct; ovules 2–5, apical, collateral or clustered. Fruits aggregated follicles or achenes (Holodiscus); styles deciduous or persistent, not elongate.
Distribution
North America, Mexico, Central America, South America, Eurasia, introduced widely.
Discussion
Genera 8, species ca. 130 (6 genera, 25 species, including 3 hybrids, in the flora).
The two genera not present in North America north of Mexico are the southeastern European-western Asian Sibiraea Maximowicz (five species) and the Mexican Xerospiraea J. Henrickson (one species).
The base chromosome number for Spiraeeae is x = 9.
Selected References
None.
