Sedum niveum Davidson
Habit: Plant 3--9 cm, matted; rosettes dense, 0.6--1.7 cm diam, internodes generally not visible, generally < 1 mm. Leaf: 5--9 mm, 1--3 mm thick, oblong to spoon-shaped, tip rounded to wide-acute. Inflorescence: 1--2 cm, 1--9-flowered. Flower: petals spreading to reflexed, 5--8 mm, lanceolate, acute, white, pink-streaked; anthers red to black. Fruit: fused at base, 5--7 mm, erect. Seed: +- 0.5 mm. Chromosomes: n=16.
Ecology: Rocky ledges, crevices; Elevation: 2100--3000 m. Bioregional Distribution: SnBr, e PR (Santa Rosa Mtns), DMtns (New York Mtns); Distribution Outside California: Baja California. Flowering Time: Jun--Aug Note: Sedum pinetorum Brandegee, Congdonia pinetorum (Brandegee) Jeps. are possible synonyms of Sedum niveum.
Synonyms: Sedum pinetorum Brandegee; Congdonia pinetorum (Brandegee) Jeps.
Unabridged Note: Sedum pinetorum Brandegee and Congdonia pinetorum (Brandegee) Jeps. are treated here, at least for the time being, as synonyms of Sedum niveum Davidson. Clausen (1975: 186) stated, "Many details of the description of Sedum pinetorum T.S. Brandegee suggest a small specimen of S. niveum. These include tuberous roots, basal cohesion of petals, yellow nectaries, and erect follicles. Discrepancies include arrangement of leaves --- 'opposite' in Sedum pinetorum and alternate in Sedum niveum; length of petals --- '3.5 mm.' in Sedum pinetorum versus 5--10 mm. in Sedum niveum; and color of seeds --- 'red' in Sedum pinetorum versus dark brown or red-brown in Sedum niveum. The validity of these differences may be questionable. The type collection of Sedum pinetorum is so fragmentary that accurate interpretation is difficult. Evidence is conflicting. Accurate identification of Sedum pinetorum awaits rediscovery of similar plants. If Sedum niveum someday is found along the eastern slope of the Sierra Nevada and plants represented by the two names are determined to belong to the same sp., then Sedum pinetorum would be the correct name for the sp. because it predates Sedum niveum by five years." In Eggli (2003) a description is given for Sedum pinetorum (pp 307--307), even though it is also said of this taxon, "Status uncertain; probably identical with S. niveum".
