Family description, key to genera by Barbara Ertter and Dieter H. Wilken.
Perennial to shrub, often bramble-forming, often prickly, prostrate or clambering to erect
Leaves generally palmately lobed to compound; leaflets often stalked, toothed
Inflorescence various
Flower: hypanthium shallow; bractlets 0; sepals 5, generally reflexed, tips generally linear; petals 5; stamens generally > 20; pistils few–many, ovaries superior, jointed to slender to club-shaped styles
Fruit: aggregate of sweet, fleshy-coated achenes (drupelets) that generally separate jointly from receptacle (raspberry-like) or separate jointly with part of fleshy receptacle (blackberry-like)
Species in genus: 200–700 species: worldwide, especially n temp, Andes
Etymology: (Latin: ancient name for bramble)
Coastal forms often have smaller, hairier, rounder leaves; hybrids and other escapes from cultivated expected.

| YOU CAN HELP US make sure that our distributional information is correct and current. If you know that a plant occurs in a wild, reproducing state in a Jepson bioregion NOT highlighted on the map, please contact us with that information. Please realize that we cannot incorporate range extensions without access to a voucher specimen, which should (ultimately) be deposited in an herbarium. You can send the pressed, dried collection (with complete locality information indicated) to us (e-mail us for details) or refer us to an accessioned herbarium specimen. Non-occurrence of a plant in an indicated area is difficult to document, but we will especially value your input on those types of possible errors (see automatic conversion of distribution data to maps). |
