01Narrative

Schizodium bifidum é uma espécie de orquídea geralmente terrestre pertencente à subtribo Disinae, endêmica da Província do Cabo Setentrional, na África do Sul. Apresentam raízes providas de tubérculos que originam caules flexíveis, delgados e resistentes que apresentam uma roseta de folhas na base e algumas folhas lineares ao longo de seu comprimento. A inflorescência não se ramifica e comporta poucas flores espaçadas ressupinadas, com sépala dorsal provida de calcar e pétalas de ápice dividido, com pequenos lobos basais e que apresentam profunda canaleta no centro, dando a impressão de estarem divididas. O labelo é pandurado, ou seja, em formato de violão, com três áreas claramente distintas, a extremidade aguda. A coluna tem apêndices laterais bem desenvolvidos, contém duas polínias e rostelo trilobado. Crescem solo arenoso bem drenado em meio aos arbustos nas encostas das montanhas. Nada se sabe sobre sua polinização, sua floração ocasionalmente ocorre após incêndios mas não está comprovada a ligação entre os eventos. Aparentemente este espécie é pouco ou nada cultivada.

05DNA & barcoding2 sequences

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 Disa bifida has left across the world's sequence archives.

07Deep time~0.26 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 origin0.26 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 DNA1 detections

Where the DNA of Disa bifida 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.
