Eleocharis quinqueflora is a species of spikesedge known by the common names fewflower spikerush and few-flowered spike-rush. It is widespread across Europe, North Africa, northern Asia (Siberia, China, Kazakhstan, Himalayas, etc.), and North America (Canada, Greenland, northern and western US). There are also isolated populations in Argentina and Chile.Kew World Checklist of Selected Plant FamiliesBiota of North America Program, 2013 county distribution mapAltervista Flora Italiana, Giunchina a 5 fiori, Eleocharis quinqueflora (Hartman) Schwarz includes photos plus distribution maps for Europe and North AmericaBoulos, L.

Monographs in systematic botany from the Missouri Botanical Garden 107(1–3): i–xcvi, 1–3348. Eleocharis quinqueflorais a resident of wet meadows, bogs, hot springs, and other moist places. This is a rhizomatous perennial approaching a maximum height of 40 centimeters. The thin, flattened stems are surrounded by papery reddish to green leaf sheaths and topped with dark inflorescences. The spikelet is lance-shaped to oval and less than a centimeter long. It contains two to seven flowers, each of which is covered with a brown or black bract. The fruit is a yellow-brown achene two or three millimeters long.Flora of North America, Eleocharis quinqueflora (Hartmann) O. Schwarz, Mitt. Thüring. Bot. Ges. 1: 89. 1949.

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 Eleocharis quinqueflora has left across the world's sequence archives.
At a glance
★ 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.
The complete instruction manual Eleocharis quinqueflora carries — its genome. We read it from three angles — how big it is, how the DNA is packed into chromosomes, and how completely it has been sequenced — and explain how to read each value as you go.
Genome sizehow big the whole instruction manual is
Measured in base pairs (bp) — the individual letters of DNA (human ≈ 3.2 Gb, a bacterium a few million). The chart places this genome on a logarithmic scale — each step to the right is ten times bigger — among reference organisms. Across species a bigger genome loosely tracks with larger cells, slower growth and lower-energy lifestyles (powered flight favours small genomes) — yet it does not imply more genes or a more advanced organism (the long-standing C-value paradox).
Chromosomes & ploidyhow the DNA is packaged
2n is the full chromosome count in a normal body cell; n is a gamete (egg or sperm), which carries half. Ploidy is how many complete chromosome sets each cell holds — 2× (diploid) is typical for animals, while higher levels (polyploidy) are common in plants.

Sequencing statusassembly quality — how far to trust these numbers
Assembly level tells you how finished the sequence is — from fragmented contigs, through scaffolds, up to a full chromosome-level assembly. BUSCO % estimates completeness: the share of genes expected to be present that were actually found. These describe the data quality, not the organism.
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.

Cultivated / Captivenot free-living
A living individual in a botanical garden, zoo or nursery — cultivated or kept, not free-living.
Where the DNA of Eleocharis quinqueflora 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.
Signal
Where its DNA was found
How strong is each trace?
Modelled climatemodelled
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.
