SEDUM

Melinda F. Denton

Generally per from rhizomes or stout, scaly caudex, generally glabrous
Leaves sessile, generally alternate, generally obovate to spoon-shaped
Inflorescence generally raceme- to panicle-like
Flower: sepals 4–5, free to fused below, < petals, obtuse to long-tapered; petals 4–5, free or fused below, erect to spreading; stamens 8 or 10, in 2 whorls, barely epipetalous; pistils 4–5, free or fused below,
Fruit erect or spreading
Seeds many, elliptic, often winged at both ends
Etymology: (Latin: to assuage, from healing properties of houseleek, to which Sedum was applied by some authors)

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).
