De bosogentroost is een eenjarige plant uit de bremraapfamilie (Orobanchaceae) en is een halfparasiet. De soort komt van nature voor in Noordwest- en Midden-Europa en Azië en is van daaruit verspreid naar Noord-Amerika. De soort is inheems in Nederland en België. In Nederland is het een zeldzame soort. Het aantal chromosomen is 2n = 44. De bosogentroost lijkt veel op de stijve ogentroost en wordt door Heukels als een synoniem beschouwd van de stijve ogentroost. De stengel van de stijve ogentroost is niet behaard, terwijl die van bosogentroost wel behaard is. De plant wordt 10-40 cm hoog met vertakte, fijn behaarde stengels. De brede, elliptische tot langwerpig-driehoekige, donker- of paarsgroene, tot 12 mm lange bladeren zijn vaak behaard en hebben een getande bladrand. Aan de onderkant van het blad springen de nerven iets uit. De afstaande, eironde schutbladen hebben aan beide kanten vier tot zes spitse of kort genaalde tanden. De bosogentroost bloeit vanaf juni tot in oktober met witte, 5-8 mm grote, tweelippige bloemen, waarvan de bovenlip soms blauw aangelopen of lila is. De onderlip heeft als honingmerk een gele vlek. De buitenzijde van de bloemkroon is behaard. De kelk is 4-6 mm lang en heeft eivormige, 2-3 tandige lobben. De bloemkroonbuis steekt niet of nauwelijks uit de kelkbuis. De helmknoppen zijn donkerbruin. De vrucht is een 4-6 mm lange doosvrucht, die iets korter dan of even lang is als de nog aanwezige kelk. Het 1,2–1,6 mm lange, smal ellipsoïd-langwerpige zaad is geribbeld. De bosogentroost groeit op vrij droge, voedselarme grond in grasland, heide, zeeduinen en bosranden.

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 Euphrasia nemorosa 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 Euphrasia nemorosa 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.

Where the DNA of Euphrasia nemorosa 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.
