Higher Taxonomy
Family: ViburnaceaeView DescriptionDichotomous Key
Common Name: MUSKROOT FAMILY
Habit: [Perennial herb], subshrub to tree; hairs often stellate or glandular. Leaf: generally opposite, simple or compound, generally toothed; stipules generally 0. Flower: generally bisexual; calyx teeth or lobes [2]5; corolla small, radial, rotate, lobes [3--4]5; stamens [4]5, epipetalous; ovary +- inferior, chambers 1 or 3--5, 1-ovuled; styles +- 0 or 3--5. Fruit: drupe.
Genera In Family: 5 genera, 200 species: especially northern temperate, also South America, southeastern Asia, tropical Africa. Note: Incl in Caprifoliaceae in TJM (1993), and possibly in future. Viburnaceae adopted as a conserved name in 2016 [Taxon 65(4):878--879, August 2016], so must be used instead of Adoxaceae for all taxa previously said to belong to Adoxaceae.

Genus: ViburnumView DescriptionDichotomous Key


Habit: Shrub, slender, generally hairy, also +- glandular, especially in inflorescence, generally deciduous. Leaf: simple, entire to lobed. Inflorescence: compound cyme, umbel-like, generally terminal, rounded or +- flat-topped, generally with oblanceolate bracts, marginal flowers larger, sterile or all flowers +- alike; peduncles 1.5--4 cm; rays generally 7. Flower: ovary chambers 1 (2 abort), ovule pendent; style short, stigma lobes 3. Fruit: drupe, drupe-like. Seed: 1.
Etymology: (Latin: for pliable branches used in binding) Note: Viburnum rigidum naturalized in SnFrB (Tilden Park); material previously identified as Viburnum edule belongs instead to Viburnum opulus.

Viburnum opulus L.
NATURALIZED
Leaf: petiole 11--29[50] mm, with a few large glands distally, without nonglandular hairs; blade 4--12 cm, +- widely elliptic, 3-lobed, dentate. Inflorescence: 1.5--2.6 cm; marginal flowers larger, sterile. Flower: marginal 20--35 mm diam, others 4--4.5 mm diam. Fruit: 6--12 mm, ovoid, yellow to orange-red.
Ecology: Spring-fed montane riparian/montane meadow habitats; Elevation: 300--900 m. Bioregional Distribution: CaRH; Distribution Outside California: circumboreal. Flowering Time: May--Jul Note: In addition, may be naturalizing in Klamath Ranges and northern High Sierra Nevada. Viburnum edule (Michx.) Raf. differs in several ways, including lack of petiole glands and having all flowers +- alike and fertile.
Synonyms: Viburnum edule (Michx.) Raf., misappl.

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.
