Cornus × unalaschkensis is a species of flowering plant in the Cornaceae, the dogwood family. Common names for the plant include Alaskan bunchberry, western cordilleran bunchberry, or simply western bunchberry. The species is native to the west coast of North America from Alaska to California, as well as Magadan in Russia. In the northwestern United States it is a common plant, even abundant. This is a rhizomatous subshrub with stems up to 20 cm tall. Leaves are borne in a whorl and are oval in shape and up to 8 cm long. The leaves are hairless to hairy. Flowers are borne in a cyme inflorescence, but are much smaller than the four white or pinkish bracts surrounding them. These bracts are 1 or 2 cm long; the petals at the center are only about a millimetre long. The fruit is a bright red drupe 6 to 8 mmm in length. Its habitat includes forests and bogs, especially with layers of decaying matter. The taxonomy of this plant is not entirely certain. This particular plant is not always considered a species in its own right. It is sometimes called a hybrid, or Cornus × unalaschkensis. Sometimes it is listed as the same species as Cornus canadensis. However, many authors consider it to be an allopolyploid, with chromosomes descended from C. canadensis and C. suecica. The three species can be told apart by careful examination of the petal and leaf morphology. Also, C. unalaschensis does not usually grow in the same regions as the other two plants. The fruit of this plant is edible, and has been used for food by various Native American groups, such as the Bella Coola and Kitasoo. For example, the Haisla mixed the berries with oolichan grease and served the mash for dessert.

A DNA barcode is a short, standardised stretch of genes that works like a fingerprint — enough to tell one species from another. Below is the molecular trace Cornus has left across the world's sequence archives.

★ the standard DNA barcode for this group — the short region actually read to tell this species apart. The rest are extra genes sequenced along the way.
How far back this lineage goes — and how we know. Everything here is measured in Ma, short for “mega-annum”: millions of years ago. The chart reads left to right like a calendar of the Earth, from the deep past on the left to today at the right edgetop to bottom like a core drilled through the Earth, from the deep past at the top down to today at the bottom.

When this lineage existed
How to read this: the coloured strip along the bottomdown the left is the geological calendar — the standard periods (Jurassic, Cretaceous…) every museum uses, shown so you can see which chapter of Earth's history this lineage lived in. The dashed rules marked ✦ are the five great mass extinctions. The solid bar is the fossil range: the span between the oldest and the youngest fossil that palaeontologists have assigned to Cornus. Above itBeside it, the bars count how many dated finds fall in each slice of time; the tallest bar is labelled, and heights use a square-root scale so that thin slices stay visible next to rich ones. Read this as how well each stretch of time is preserved and studied — thick bars mean plenty of the right kind of rock and plenty of collectors, which is related to, but not the same as, how common it actually was.

Cultivated / Captivenot free-living
A living individual in a botanical garden, zoo or nursery — cultivated or kept, not free-living.
Where the DNA of Cornus was picked up in samples of water, soil or air — nobody saw the organism, only its DNA left behind. A trace is a clue that the species was near, not a confirmed sighting.

How to read this: each dot is one detection of this species' DNA in an environmental sample. The confidence meter weighs how many independent studies and places back up the signal — one detection in one study is a hint; many across several studies is solid. Records dated before 2008 (when eDNA methods began) are treated as likely mislabeled and left off the map.
