Food uses

Disclaimer: The information provided here is for reference and historical use. We do not recommend nor do we condone the use of this species for food purposes without first consulting a physician.

Moerman, 1998 Native Americans used the berries to make wine, pies, jellies, sauces, porridges, and also eaten raw. Also the blossoms were dipped in hot water to make a pleasant drink.

Medicinal uses

Disclaimer: The information provided here is for reference and historical use. We do not recommend nor do we condone the use of this species for medicinal purposes without first consulting a physician.

Moerman, 1998 Used by Native Americans to treat rheumatism, burns, skin problems, headaches, liver troubles, colic, jaundice, stomach problems, heart disease, measles, diphtheria, mumps, venereal disease, fever, and toothache. They also used this species as an emetic, laxative, cathartic, blood purifier, tonic, and diuretic.

Other uses

Moerman, 1998 Native Americans used the stems to make popguns, water squirt guns, and blowguns; stems also used to make medicine blowing tubes. They also used the inner bark to make a repellant to ward off flies and other insects.

Poisonous properties

Burrows, 2001 Although fruits have been used for food and beverage products, ingestion of raw fruit as well as other parts has caused digestive tract problems. Symptoms usually include nausea, vomiting, diarrhea, and profuse salivation. Other signs occasionally observed include abdominal pain, weakness, dizziness, incoordination, labored respiration, and numbness. Death is unlikely. Generally, adverse affects do not arise when the fruits are cooked or fermented, processes which perhaps denature the tertiary structures of the bioactive constituents.

Nomenclature

A recent author (Bolli, 1994) has reduced the American Sambucus canadensis to varietal status within a circumpolar S. nigra s.l. complex. For now, the more traditional approach has been followed with S. canadensis maintained as a distinct species in this treatment.

The name Sambucus is derived from an erroneous tenth-century Anglo-Saxon translation of the "Herbarium of Apuleius", a work written in the fourth century, spuriously attributed to the second century Roman philosopher and poet. In chapter cxlviii the translator misidentified a Greek word of Coptic origin as the elder which was adopted by ante-Linnaean botanists and perpetuated to this day. Gerard, 1895

Description

HABIT Perennial, deciduous, phanerophytic, stoloniferous shrub, monoclinous, 1-4 m tall.

STEMS Main stems ascending or erect, round. Bark smooth, not exfoliating, brown or light gray or gray, with prominent lenticels. Branches erect or ascending, spring orthotropic shoots later give rise to plagiotropic summer shoots which sprout from buds of spring shoots and become woody in late summer of the same year. Twigs light orange-red or light yellowish green or light green or green, odoriferous, terete, 3-5 mm in diameter, lenticellate, glabrous, occasionally glaucous. Pith white, round, continuous, spongy. Sap translucent. For a detailed analysis of shoot vascularization see Esau, 1945

BUDS Axillary only, scattered along stem; axillary buds 1 per axil, 4 mm long. Bud scales dark orange-red, imbricate, membranaceous, glabrous, eglandular, margins ciliate. Bud scale scars not encircling the stem. Leaf scars broadly crescent-shaped, vascular bundle scars 3, U-shaped.

LEAVES Opposite, once pinnately compound, 2 per node, spaced somewhat evenly along stem, divergent from stem. Stipules present or absent, lateral, free from the petiole, leaf-like or gland-like or transitional; often caducous. Leaves petiolate, petiole terete, glabrous, eglandular. Leaf blades: abaxial surface light green, adaxial surface green, bilaterally symmetric, 25-60 cm long, abaxial surface glabrous or with long and unbranched hairs, erect or spreading, dark orange-red or white, sparse or moderately dense, distributed throughout. Adaxial surface glabrous or with long and unbranched hairs, erect or spreading, dark orange-red or white, sparse or moderately dense, distributed throughout. Leaflets petiolulate, 5-11, usually 5-7, glabrous or with short and unbranched hairs. Petiolules furrowed, 0.1-1.3 cm long, glabrous or with long and unbranched hairs, often with reddish hairs. Leaflets lanceolate or ovate or widely ovate, 6-11 cm long, 2-5.5 cm wide, base acute or cuneate or obtuse, margin serrate, apex acuminate or acute. For a discussion regarding the stipules and their production of extrafloral nectar see Bolli, 1994

INFLORESCENCES Bisexual, compound, terminal umbelliform cyme. Peduncle 8-13 cm long, glabrous, eglandular. Bracteoles 2, at apex of pedicel, margin entire, glabrous, eglandular, minute.

FLOWERS Serotinous, formed on the current season's growth, bisexual, with sepals and petals readily distinguishable from one another, 5-merous, (occasionally 6-merous) 4-5 mm wide, fragrance present, perianth of two whorls. Calyx actinomorphic, of fused sepals, persistent. Sepal lobes 5, triangular, 0.5-1 mm long, margin entire, apex acute, abaxial surface glabrous, eglandular. Corolla actinomorphic, acetabuliform, of free petals, deciduous, abaxial and adaxial surfaces the same color, light yellow or white. Petals 5, 2-3 mm long, margin entire, apex obtuse, abaxial surface glabrous, eglandular, adaxial surface glabrous, eglandular. Gynoecium syncarpous. Locules 3-4. Stigmas 1, 4(3-5) lobed, sessile. Ovary inferior, glabrous. Placentation axile. Androecium epipetalous, haplostemous, extrose. Stamens 5, 2-3 mm long. Anthers yellow, glabrous, filaments straight, glabrous. For a detailed investigation of floral micro-anatomy and morphology see Wilkinson, 1948 For a detailed survey of pollen morphology see Bolli, 1994; Samutina, 1986

FRUITS Drupe, dark violet-blue to black (f. rubra and var. aurea have red fruit), ovoid, 4-6 mm long, 4-6 mm wide, glabrous, eglandular. ?(f. chlorocarpa - greenish)

SEEDS Seeds 3-5, light brown, 2-4 mm long, 1.5-2 mm wide, glabrous, eglandular, rugose.

Habitat

Usually in wet conditions with somewhat rich soils including swamps, marshes, wet woods, roadside ditches, lake and pond shores, river margins, stream banks, moist thickets and swales. Occasionally found in more mesic situations such as old fields, upland mixed woods, and one herbarium label stated "dry shale outcrop".

Distribution

Indigenous to North America except Utah-Nevada to the Pacific Northwest.

Germination

 Schopmeyer, 1974; Rose, 1919; Davis, 1927; Hidayati, 2000

 Seeds have deep simple morphophysiological dormancy, although some early researchers reported that some seed may not be dormant. The best results have come from warm stratification followed by cold stratification in moist sand to break dormancy. Germination was best using 14 hour photoperiods at 15-25 degrees C. Germination is epigeous. Dry seed (with the pulp removed) stored in sealed containers at 41 degrees F for two years showed little or no loss of viability.
