Solandra grandiflora, the showy chalicevine, or papaturra is a member of the nightshade ( Solanaceae ) genus Solandra and, like the other members of the genus, is a climbing plant with large, attractive, trumpet-shaped flowers. It is native to Central America and northern South America and is widely grown in the tropics as an ornamental.Lötschert, W. & Beese, G. ( translated by Clive King ) 1994 Collins Photo Guide to Tropical Plants pub. Harper Collins. . Page 51. The green parts of the plant are highly toxic (hallucinogenic / delirient in small doses), due to tropane alkaloid content,https://wiki.tripsit.me/wiki/Cup_of_Gold Retrieved at 11.48am on 17/5/19 and have caused deaths from anticholinergic poisoning,Quattrocchi, Umberto (2012). CRC World dictionary of medicinal and poisonous plants: common names, scientific names, eponyms, synonyms and etymology, pub. CRC Press Taylor and Francis Group. Vol. V: R-Z pps. 308-9. but the flesh of the ripe fruit ( although not the unripe fruit or seeds ) is said to be edible. The fruits, which are globular and largely enclosed by the accrescent calyces, can reach a kilogram in weight and have a taste described as apple-like or melon-like.

05DNA & barcoding8 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 Solandra grandiflora has left across the world's sequence archives.

06Genome at a glanceCCDB
The complete instruction manualSolandra 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.

Where the DNA of Solandra 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 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.
