01Narrative

Dicranostegia is a monotypic genus of hemiparasitic flowering plants belonging to the family Orobanchaceae, containing the species Dicranostegia orcuttiana, commonly known as Orcutt's bird's beak or Baja bird's beak. It is near-endemic to Baja California, found from Miller's Landing north to Tijuana, but has a few occurrences in southern San Diego County, California. It is differentiated among other similar species (like Cordylanthus spp.) in California by its leaves with 8 to 11 lateral lobes that are paired. It was formerly placed in the genus Cordylanthus until phylogenetic analysis led to it being split off. This species is threatened by the destruction of its habitat from urbanization.

05DNA & barcoding2 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 Dicranostegia orcuttiana has left across the world's sequence archives.

06Genome at a glanceCCDB

The complete instruction manual Dicranostegia orcuttiana 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 Dicranostegia orcuttiana 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 strong is each trace?

DNA read depthRead counts were not reported for this species — the map shows presence only, not how strong each trace was.

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.
