01Narrative

Typhonodorum lindleyanum, botanic garden on Mahé, Seychelles, March 2016. Typhonodorum is a monotypic genus of flowering plants in the family Araceae. The single species making up this genus is Typhonodorum lindleyanum. The genus is native to Madagascar, the Comores, Zanzibar, Réunion and Mauritius.Kew World Checklist of Selected Plant Families This genus is believed to be closely related to Peltandra even though Peltandra is only found in North America and there don't appear to exist closely related genera in the African mainland. There isn't fossil evidence to link the two genera so it has been proposed that there once was a genus in Africa from which the two genera had originated. The African mainland genus spread to North America and to Madagascar 50 million years ago before it broke off. Then the African genus became extinct and the North American and Madagascan genera remained.Bown, Demi (2000). Aroids: Plants of the Arum Family. Timber Press. .

05DNA & barcoding6 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 Typhonodorum lindleyanum has left across the world's sequence archives.

06Genome at a glanceCCDB

The complete instruction manual Typhonodorum lindleyanum 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.

07Deep time~29.3 Ma lineage

How far back this lineage goes — and how we know. Everything here is measured in Ma, short for “mega-annum”: millions of years ago. The chart reads left to right like a calendar of the Earth, from the deep past on the left to today at the right edgetop to bottom like a core drilled through the Earth, from the deep past at the top down to today at the bottom.

DNA clock origin29.3 Ma TimeTree

When this lineage existed

How to read this: the coloured strip along the bottomdown the left is the geological calendar — the standard epochs (Pliocene, Pleistocene…) every museum uses, shown so you can see which chapter of Earth's history this lineage lived in. This lineage is a young one, so the strip is zoomed in to epochs — the finer subdivisions inside a period. The orange marker is the DNA clock: DNA accumulates mutations at a roughly steady rate, so comparing this species' DNA with its relatives estimates when the lineage split off — independently of any fossil.

09Environmental DNA6 detections

Where the DNA of Typhonodorum lindleyanum 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.
