Sedum rupicola G.N. Jones[FNA8, HC2]
cliff stonecrop, curved-leaf stonecrop

Publication: Res. Stud. State Coll. Wash. 2: 125. 1931.

Origin: Native

selected vouchers: WTU

Notes: FNA8: "The leaves of Sedum rupicola detach very easily and the fallen ones sprout and produce plantlets from their bases. R. T. Clausen (1975) considered S. rupicola to be most closely related to S. lanceolatum. He recognized it as a species because, although it sometimes grows sympatrically with S. lanceolatum, the two do not hybridize, and because S. rupicola flowers a week earlier and grows in soils of higher pH than does S. lanceolatum. The general morphological differences are: in S. rupicolum leaves of sterile shoots are ovate and detach easily, sepals have obtuse apices, petals have minutely mucronate tips (0.1 mm), and nectaries are deep yellow; in S. lanceolatum leaves of sterile shoots are linear-lanceolate and do not detach easily, sepals have acute apices, petal apices are long-acuminate (0.8 mm), and nectaries are pale yellow."
