GROSSULARIACEAE

GOOSEBERRY FAMILY

Michael R. Mesler and John O. Sawyer, Jr.

Shrub generally < 2 m
Stem generally erect; nodal spines 0–9; internodal bristles generally 0; twigs generally hairy, generally glandular
Leaves simple, alternate, generally clustered on short, lateral branchlets, petioled, generally deciduous; blade generally palmately 3–5-lobed, generally thin, generally dentate or serrate, base generally cordate
Inflorescence: raceme, axillary, generally pendent, 1–25-flowered; pedicel generally not jointed to ovary, generally hairy or glandular; bract generally green
Flower bisexual, radial; hypanthium tube exceeding ovary; sepals generally 5, generally spreading; petals generally 5, generally < sepals, generally flat; stamens generally 5, alternate petals, generally inserted at level of petals (hypanthium top), anthers generally free, generally glabrous, tips generally rounded; ovary inferior, chamber 1, ovules many, styles generally 2, generally fused except at tip, generally glabrous
Fruit: berry
Genera in family: 1 genus, 120 species: n hemisphere, temp South America. Some cultivated as food, ornamental. Hypanthium data refer to part above ovary; statements about ovary hairs actually refer to the hypanthium around the ovary. Formerly included in Saxifragaceae.

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).
