Sedum sanhedrinum

Sedum sanhedrinum SANHEDRIN STONECROP

Higher Taxonomy

Family: Crassulaceae

Common Name: STONECROP FAMILY
Habit: Annual to shrub [+- tree-like or climbing], fleshy. Leaf: generally simple, alternate or opposite (whorled), in dense to open, basal (or terminal) rosettes, or basal and cauline (not in rosettes), reduced on distal stem or not, often +- red. Inflorescence: generally a cyme, panicle-like, generally bracted. Flower: generally bisexual; sepals generally 3--5, generally +- free; petals generally 3--5, +- free or fused; stamens >> to = sepals, epipetalous or not; pistils generally 3--5(--8), simple, fused at base or not, ovary 1-chambered, placenta 1, parietal, ovules 1--many, style 1 per pistil. Fruit: follicles, generally 3--5. Seed: 1--many, small.
Genera In Family: +- 33 genera, +- 1400 species: +- worldwide, especially dry temperate; many cultivated for ornament. Note: Water-stressed plants often +- red. Consistent terminology regarding leaves, bracts difficult; in Aeonium and Dudleya, structures in rosettes are leaves, those on peduncles are bracts, and those subtending flowers are flower bracts; thus in taxa where the inflorescence is terminal, rosette leaves may "become" bracts as stem rapidly elongates to form an inflorescence. In Sedum structures below the inflorescence are interpreted as stems and leaves, not peduncles and bracts. Seed numbers given per follicle. SCIED: Scientific Editor: Bruce G. Baldwin, Thomas J.

Sedum sanhedrinum A. Berger

NATIVE
Habit: Perennial herb, rhizomes stout; stems, rosette leaves, inflorescences, and sepals lacking thick granular wax. Stem: 5--23 cm, glabrous, slightly glaucous; rosettes dense in sunny sites, internodes generally obscured, < 3 mm. Leaf: strongly flattened, rosette leaves > stem leaves, 20--30 mm, 6--9 mm wide, obovate to broadly obovate or oblanceolate, tip obtuse or acute, rarely notched; stem leaves alternate, 8--17 mm, ascending to spreading, obovate to broadly obovate, oblanceolate, oblong, or elliptic. Inflorescence: head-like to cylindrical or flat-topped, 7--8.5 cm, 13--40(--72)-flowered. Flower: calyx lobes 2.5--4 mm, 33--50% as long as petals; petals 6--10 mm, yellow to whitish with pink or red midribs, bases often pale orange or pink, erect, tips blunt to acute; filaments yellow to white or green; anthers yellow (dull orange), aging pink, red, white, or yellow. Fruit: follicles 5--9 mm, erect. Seed: 1.3--1.5 mm, narrowly lanceolate, shiny, faintly striate.
Ecology: Dry rocky slopes, ridges, talus, full sun or partial shade; on varied substrates including serpentine; Elevation: 1400--2300 m. Bioregional Distribution: NCoRH (Glenn, Lake, Mendocino, and Tehama cos.). Flowering Time: Jun--Aug Note: Blunt erect petals distinctive. Chromosome count of n=30 reported as S. laxum subsp. retusum (Clausen & Uhl 1944) based on a gathering of S. laxum subsp. heckneri (Goodspeed 28.3, BH); no vouchered counts published for S. sanhedrinum. In lateral view, flowers vary from ovate to slightly hourglass-shaped, as in S. obtusatum.

Geographic subdivisions for Sedum sanhedrinum: NCoRH (Glenn, Lake, Mendocino, and Tehama cos.).	MAP CONTROLS 1. You can change the display of the base map layer control box in the upper right-hand corner. 2. County and Jepson Region polygons can be turned off and on using the check boxes.

(Note: any qualifiers in the taxon distribution description, such as 'northern', 'southern', 'adjacent' etc., are not reflected in the map above, and in some cases indication of a taxon in a subdivision is based on a single collection or author-verified occurence).	Data provided by the participants of the Consortium of California Herbaria. MAP LEGEND View all CCH records All markers link to CCH specimen records. The original determination is shown in the popup window. Blue markers indicate specimens that map to one of the expected Jepson geographic subdivisions (see left map). Purple markers indicate specimens collected from a garden, greenhouse, or other non-wild location. Yellow markers indicate records that may provide evidence for eFlora range revision or may have georeferencing or identification issues. READ ABOUT YELLOW FLAGS CCH collections by month Duplicates counted once; synonyms included. Species do not include records of infraspecific taxa, if there are more than 1 infraspecific taxon in CA. Blue line denotes eFlora flowering time (fruiting time in some monocot genera).
