Sisyrinchium albidum, commonly known as white blue-eyed grass, is a species of flowering plant in the family Iridaceae. The stem of Sisyrinchium albidum is commonly pale grey and threadlike, measuring 0.2 to 0.5 m high and 0.5 to 1 mm wide. Similarly, its narrow, stiff leaves are 0.5 to 1 mm wide. Its twinned spathes (by which it is characterized, along with its leaves) are green and purple-tinged and 1.5 to 2 cm high. The outer part of the flower, including the petals, is white to violet and 8–10 mm long. Its fruits are 2–4 mm long and a pale yellow-green. It is found mostly in eastern North America.

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 Sisyrinchium albidum has left across the world's sequence archives.

06Genome at a glanceCCDB
The complete instruction manualSisyrinchium albidum 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.
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.

Where the DNA of Sisyrinchium albidum 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.
