GENUS CODE: RHUS GENUS SCIENTIFIC:Rhus GENUS AUTHORITY: L. GENUS COMMON: Sumac GENUS SUMMARY: A genus of about 35 species, trees, shrubs, and lianas, temperate and subtropical, of Eurasia, Hawaii, North America, and n. Central America. The subgenera and sections follow Andrés-Hernández et al. (2014). GENUS IDENTIFICATION: Identification notes: Two hybrids have been documented to occur naturally in our area: Rhus ×borealis Greene (glabra × typhina) and Rhus ×ashei (Small) Greene (glabra × michauxii). They are intermediate between their parents. For instance, R. ×ashei has sparsely pubescent leaves and stems, slight winging of the rachis between the terminal leaflets, greater potential stature than R. michauxii, and leaflets with a length/width ratio of 2.5-3. Hardin & Phillips (1985b) discuss other natural and artificial hybrids in Rhus. GENUS REFERENCES: Barkley (1937)=Z; Andrés-Hernández et al.

Plant Sale Text: Stag-Horn Sumac is a shrub or small tree frequently found along roadsides and other sunny areas in the mountains. Its flowering clusters (female plants) are loved by honeybees. Later bright red berries attract many bird species through the winter. Perfect even on impossible slopes. The shades of blaze- orange leaves tinged with red in early autumn is unlike any other color display among our native trees or shrubs.

HABITAT: Roadsides, old pastures, thickets, clearings, rock outcrops, barrens.
COMMENTS: NS and NB west to MN, south to n. GA, AL, MS, and KS . The apparently older epithet hirta was formally rejected in 1999. The species, especially in its cut-leaved forms, forma laciniata (Wood) Rehder and forma dissecta Rehder, is very popular in Europe as a cultivated ornamental.
