01Narrative

Mucronea californica is a rare species of annual plant in the family Polygonaceae known by the common names California spineflower or California mucronea. An ephemeral plant found growing in the sandy microhabitats of coastal sage scrub, chaparral and dunes, this plant is threatened by the urbanization and development of its viable habitat and has been locally extirpated over much of its range. It has small, white to pink flowers that top inflorescences spined with awns.

05DNA & barcoding3 specimens

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 Mucronea californica has left across the world's sequence archives.

06Genome at a glanceCCDB

The complete instruction manual Mucronea californica 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. Click any value below to see the underlying records and sources.

09Environmental DNA2 detections

Where the DNA of Mucronea californica 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.
