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

See the CNPS Inventory for information about endangerment and rarity.| 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). |
