GENUS INDEX

GENUS CODE: HEUCH
GENUS SCIENTIFIC: Heuchera
GENUS AUTHORITY: L.
GENUS COMMON: Alumroot
GENUS SUMMARY: [contributed by R.A. Folk and A.S. Weakley]
GENUS IDENTIFICATION: Identification notes: Vegetatively, Heuchera resembles Tiarella and Mitella. Heuchera usually has leaves as wide as long and with prominent variegation, while Tiarella and Mitella usually have leaves longer than wide and lacking variegation.
GENUS REFERENCES: Folk & Freudenstein (2014); Folk & Freudenstein (2015)=X; Wells & Shipes in FNA (2009); Wells (1984)=Z; Rosendahl, Butters, & Lakela (1936)=Y; Wells (1979); Soltis in Kubitzki, Bayer, & Stevens (2007). The keys partly adapted from Wells (1984).

FAMILY INDEX

FAMILY CODE: SAXIFR
FAMILY SCIENTIFIC: Saxifragaceae
FAMILY AUTHORITY: A.L. de Jussieu 1789
FAMILY COMMON: Saxifrage Family
FAMILY SUMMARY: If narrowly circumscribed (as here), a family of about 35 genera and 500-650 species, herbs (mianly perennial), nearly cosmopolitan, but especially diverse in warm temperate and cold temperate regions of North America and Eurasia. The circumscription of a much narrower Saxifragacaeae is clearly warranted, based on a wide variety of data, and strongly corroborated by molecular data (Morgan & Soltis 1993 and many later references).

WEAKLEY FLORA

SCIENTIFIC NAME: Heuchera pubescens
COMMON NAME: Marbled Alumroot
SYNONYMY: [= FNA, K, Pa, WV; < H. pubescens - C, S, W, Z (also see H. alba); >< H. pubescens var. brachyandra Rosendahl, Butters, & Lakela - F, G, Y; > H. pubescens var. pubescens - F; > H. pubescens var. typica - Y]
PHENOLOGY: May-Jul.
HABITAT: Rocky forests, rock outcrops, particularly where soils are subacidic or circumneutral.
COMMENTS: Primarily a species of the Ridge and Valley Province of PA, MD, WV, and VA, H. pubescens ranges south to only a few locations in the upper Piedmont of NC. See discussion under H. alba. The report in RAB of the occurrence of H. pubescens in Madison County, NC, is apparently erroneous; Wells (1984) shows H. pubescens reaching its southern limit just south of the VA border, and not occurring at all in KY, TN, or the mountains of NC. She found the bract characters used in the key in RAB to be unreliable. Reported by Hill & Horn (1997) for South Carolina {report needs verification}.
