Samples of "Piper clusii" imported into Belgium from the Congo in 1895. Piper guineense is a West African species of Piper; the spice derived from its dried fruit is known as Ashanti pepper, Benin pepper, Edo pepper, false cubeb, Guinea cubeb, and called locally kale, kukauabe, masoro, etiñkeni, sasema, soro wisa, eyendo, eshasha'by the Urhobo people, oziza and uziza. It is a close relative of cubeb pepper and a relative of black pepper and long pepper. Unlike cubeb, which is large and spherical in shape, Ashanti pepper grains are prolate spheroids, smaller and smoother than Cubeb pepper in appearance and generally bear a reddish tinge. The stalks of Ashanti pepper berries are also distinctly curved whilst those of cubeb pepper are completely straight. The terms West African pepper and Guinea pepper have also been used, but are ambiguous and may refer to grains of Selim or grains of paradise. The plants that provide Ashanti pepper are vines that can grow up to 20 m in length, climbing up boles of trees by means of adventitious roots. These are native to topical regions of Central and Western Africa and are semi-cultivated in countries such as Nigeria where the leaves, known as uziza, are used as a flavouring for stews. Like other members of the pepper family, Ashanti pepper contains 5–8% of the chemical piperine which gives them their piquant taste. They contain large amounts of beta-caryophyllene, which is being investigated as an anti-inflammatory agent. It also contains significant proportions (up to around 10%) of myristicin, elemicin, safrole, and dillapiol, as well as some apiole (around 1.4%). In terms of flavour, Ashanti pepper is very similar to cubeb pepper but is less bitter and has a fresher, more herbaceous flavour and aroma than cubeb's more pine-like scent. Though known in Europe during the Middle Ages (it was a common spice in Rouen and Dieppe in 14th-century France), these days, its use is largely marginalized to West and Central Africa.

Compounds documented for Piper guineense across natural-product and food-composition databases — not just the ~150 nutrients on a classic label ("nutritional dark matter").
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 Piper guineense has left across the world's sequence archives.

07Deep time~12 Ma lineage
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 epochs (Pliocene, Pleistocene…) every museum uses, shown so you can see which chapter of Earth's history this lineage lived in. This lineage is a young one, so the strip is zoomed in to epochs — the finer subdivisions inside a period. The orange marker is the DNA clock: DNA accumulates mutations at a roughly steady rate, so comparing this species' DNA with its relatives estimates when the lineage split off — independently of any fossil.

09Environmental DNA2 detections
Where the DNA of Piper guineense 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 strong is each trace?
DNA read depthRead counts were not reported for this species — the map shows presence only, not how strong each trace was.
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.
