01Narrative

Phaius tankervilleae, commonly known as the greater swamp-orchid, swamp lily, swamp orchid, nun's-hood orchid, nun's orchid, veiled orchid, Lady Tankerville's swamp orchid or 鹤顶兰 (he ding lan), is a species of orchid native to areas from Asia to islands in the Pacific Ocean. It has large, pleated leaves and tall flowering stems bearing up to twenty five white, brown, mauve and yellow flowers. It was named for Lady Tankerville who owned the greenhouse where the first orchid flowered. It was the first tropical orchid to flower in England.

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 Calanthe tankervilleae has left across the world's sequence archives.

06Genome at a glanceCCDB · GIFT

The complete instruction manual Calanthe tankervilleae 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 DNA9 detections

Where the DNA of Calanthe tankervilleae 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.
