Aristolochia gorgona is a recently discovered (2002) flowering plant in the Dutchman's pipe family (Aristolochiaceae) (of the Eudicot super-order or subclass) found in the Atlantic-facing rainforests of Costa Rica and Panama. It differs from Aristolochia grandiflora in lacking the sometimes very long "tail" that hangs down from the trumpet of A. grandiflora, in being darker (sometimes even purple) and in being covered with inch-long (2.5 cm) tendril-like enations which have suggested a comparison to Medusa and her sisters.http://mobot.mobot.org/cgi-bin/search Then search "Aristolochia gorgona" With a trumpet (usually regarded as a greatly expanded calyx) up to 12.5 inches (31 cm) top to bottom, twelve inches (30 cm) wide and about 15 inches (38 cm) deep A. gorgona is one of the largest flowers in the New World.Mario A. Blanco, "Aristolochia gorgona (Aristolochiaceae) A New Species with Giant Flowers...etc." BRITTONIA Vol. 54 # 1 (2002) pp. 30 -39. Its discoverer, Blanco thought its very late discovery might be due to its similarity to A. grandiflora. This resemblance must be that of the foliage, for as we have seen the flowers are very different.

05DNA & barcoding9 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 Aristolochia grandiflora has left across the world's sequence archives.

06Genome at a glanceCCDB
The complete instruction manualAristolochia grandiflora 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.

09Environmental DNA8 detections
Where the DNA of Aristolochia grandiflora 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.
