![]() This species has long been popular thanks to the bright yellow flowers which appear early in the year, usually in March, and due to its edible and highly versatile fruit. Calyx lobes less than 0.8 mm long styles at most slightly expanded (no broader than the stigma) inflorescence strongly convex or pyramidal ripe fruit pale blue to white, on bright red pedicels bark of older branchlets gray.The Cornelian Cherry is a deciduous species native to Central and Southern Europe which thrives best in the Donau-Auen National Park in dry areas at higher elevations. 0.5–1 mm below the stigma inflorescence flat or slightly convex ripe fruit dark blue (with pale patches) on yellow-brown to maroon pedicels bark of older branchlets reddish.Ĩ. Calyx lobes (0.6–) 0.8–1.3 (–2) mm long styles abruptly swollen for ca. foemina, lateral veins of leaves 3–5 on a side.Ĩ. Pith of 2-year-old twigs light brown (darker than surrounding wood) or often white in C. 1.5 times as long as wide or longer, with 4–5 (–6) lateral veins per side.Ħ. Branchlets unspotted except for paler lenticels, the older ones usually red (rarely green) leaf blades ca. Branchlets green, flecked with purplish streaks leaf blades often less than 1.5 times as long as wide, with 6–8 (–9) lateral veins per side.ħ. Pith of 2-year-old twigs white (paler than surrounding wood) lateral veins of leaves 4–9 on a side.ħ. Leaf blades smooth to the touch above, glabrous or with soft closely appressed hairs.Ħ. Lateral veins of leaves 6–8 on a side pith white frequent throughout most of Michigan.Ĥ. Lateral veins of leaves 3–5 on a side pith usually brown in old twigs rare, only in southeastern Lower Peninsula.ĥ. Leaf blades rough to the touch above, owing to tiny projecting stiff hairs.ĥ. Flowers in a compound cyme without subtending bracts fruit white to blue, in an open infructescence.Ĥ. ![]() Flowers in a dense head-like cluster subtended by 4 large showy white (or pinkish) bracts fruit dark red, in tight heads.ģ. Leaves clearly all opposite (or in pairs at ends of shoots).ģ. Plant herbaceous leaves all or mostly in one whorl inflorescence subtended by large white bracts fruit bright red.ġ. Plant a shrub or small tree leaves all alternate (or crowded at ends of branches) inflorescence without subtending bracts fruit dark blue.Ģ. ![]() Leaves alternate or so crowded as to appear whorled, but not all distinctly opposite.Ģ. It has bright yellow flowers in compact umbels appearing in early to mid April, before the leaves expand, and conspicuous red fruit.ġ. A diverse genus, sometimes split into several.Ĭornus mas L., the European Cornelian Cherry, was collected in Ann Arbor (Washtenaw Co.) in 1949 as an “escape from cultivation,” but from a street running beside a park, and perhaps it was merely persisting from a planting. Almost any character in the keys is open to exception, but identification is easier than the apparently overlapping statements might suggest. Combinations of size, shape, texture, venation, and pubescence are rather distinctive for most species, but they do vary depending on conditions, and blades tend to be larger and less papillose beneath in the shade. ![]() They are opposite in all but one Michigan species, entire, and with parallel lateral veins arching strongly as they approach the margins. The leaves of Cornus make the genus easily recognizable. ![]()
