01Narrative

Hesperocodon hederaceus, synonym Wahlenbergia hederacea, also known as the ivy-leaved bellflower, is a species of flowering plant that is found throughout Europe. It is the only species in the genus Hesperocodon. The delicate, patch-forming, hairless perennial herb has thin, creeping stems about 20 cm in length. Its pale green leaves are long-stalked and have an ivy-shaped, rounded structure. These leaves can be described as having a cordate shape and are approximately 5–12 mm long and wide. The plant has erect, solitary, pale blue flowers in summer and autumn, with bell-shaped corolla with 5 short lobes. The flowers are 6–10 mm long x 5–8 mm wideThe Wild Flower Key, British Isles N.W. Europe, Francis Rose, WARNE, Published by the Penguin Group, 1991 reissue, and sit on fine stalks 1–4 cm long. It is suggested that the long pedicels are an adaptation to assist in seed dispersal.

05DNA & barcoding9 eDNA hits

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 Hesperocodon hederaceus has left across the world's sequence archives.

06Genome at a glanceCCDB

The complete instruction manual Hesperocodon hederaceus 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.

07Deep time~23.4 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.

DNA clock origin23.4 Ma TimeTree

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.

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.
