Alsophila cuspidata, synonym Cyathea cuspidata, is a widespread species of tree fern native to Central and South America, where it grows in tropical rain forest up to the montane zone, as well as in open sites, on riverbanks and cleared pastureland at an altitude of 0–800 m. Its natural distribution covers Mexico, Guatemala, Belize, Honduras, El Salvador, Nicaragua, Costa Rica, Panama, Colombia, Ecuador, Peru, Bolivia, Paraguay, the Amazon Basin, Brazil and French Guiana. This species often has multiple trunks, which may be 15 m tall and about 10 cm in diameter. They are covered in black spines and together form a medium-sized, feathery clump. Fronds are bipinnate and 2–3 m long. The rachis and stipe are brown to dark brown and are covered with scales. The scales are bicoloured, having a dark brown to blackish centre and a pale, whitish margin. Pinnule veins sometimes have small, brown, star-shaped scales. Sori are round and form on either side of the pinnule midvein. They are covered by globose indusia. In cultivation, A. cuspidata should be provided with high humidity and warm temperatures. It should not be exposed to frost.

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 Alsophila cuspidata has left across the world's sequence archives.

07Deep time~2.95 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.

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 Alsophila cuspidata 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.
