The Scindapsus Files — Episode 2
Argyraeus: The One With Victorian Paperwork
After Episode 1, we thought we'd give ourselves an easier case.
Argyraeus.
Surely this one would behave. It has an old name, published botanical history and even Victorian-era paperwork.
What could possibly go wrong?
Quite a lot, apparently.
In Episode 1, we followed Scindapsus pictus back through the botanical literature and discovered just how complicated a familiar plant name can become once we start asking where it actually came from.
Argyraeus gives us something different. This time, there really is an old paper trail.
But that paper trail doesn't necessarily tell us everything that modern horticulture sometimes assumes it does.
First, the paperwork
The story begins with Scindapsus pictus itself.
The species name Scindapsus pictus was published by Justus Carl Hasskarl in 1842, in Tijdschrift voor Natuurlijke Geschiedenis en Physiologie.
Then, in 1859, another name appeared:
Pothos argyraea.
This is where things get interesting.
The name is attributed to James Veitch Jr., whose botanical author abbreviation is J.Veitch f., in 1859.
There is a small bibliographic wrinkle here that I think is worth keeping rather than smoothing over. The International Plant Names Index cites Veitch's Catalogue of New and Beautiful Plants, while Plants of the World Online cites Proceedings of the Royal Horticultural Society of London 1: 38 for the same 1859 name. Both databases, however, agree on the name, author and year.
So the Victorian connection isn't simply a later nursery story attached to Argyraeus. The name itself is directly tied to James Veitch Jr. in 1859.
And the name didn't disappear there.
In 1879, Adolf Engler transferred it to Scindapsus as:
Scindapsus argyraeus.
Then, in 1898, Engler treated it as a variety of Scindapsus pictus:
Scindapsus pictus var. argyraeus.
The International Plant Names Index identifies Pothos argyraea as the basionym, or earlier name on which the later combinations were based, of both Scindapsus argyraeus and Scindapsus pictus var. argyraeus.
Today, Plants of the World Online at the Royal Botanic Gardens, Kew accepts Scindapsus pictus and treats Scindapsus argyraeus as a synonym of it.
So unlike many modern horticultural names, Argyraeus has genuine historical botanical paperwork behind the word.
That part is unusually solid.
But then came the question that sent us down another rabbit hole.
Is the Victorian Argyraeus our modern Argyraeus?
This is where we have to be careful.
Today, Argyraeus is widely used in horticulture for a recognisable silver-patterned form of Scindapsus pictus. It's tempting to look at the nineteenth-century name and draw a straight line from Victorian Argyraeus to today's Argyraeus.
Unfortunately, it isn't quite that simple.
A historical botanical name doesn't automatically establish an uninterrupted horticultural lineage. A published name tells us that material was recognised and named at that point in history. It doesn't, by itself, tell us that every plant carrying the same name in cultivation today descends clonally from that exact nineteenth-century material.
That's an important distinction.
The existence of Pothos argyraea, Scindapsus argyraeus and Scindapsus pictus var. argyraeus demonstrates that argyraeus is an old botanical epithet associated with this plant complex.
What it doesn't prove by itself is an unbroken provenance from James Veitch Jr.'s 1859 plant material to every modern plant sold as Argyraeus.
So what exactly does Veitch prove?
More than we first expected, but less than we might be tempted to claim.
It establishes that Pothos argyraea was published under James Veitch Jr.'s authorship in 1859. IPNI and POWO differ on the bibliographic citation for that publication, so rather than quietly choosing one, we've left that discrepancy visible.
That gives Argyraeus a direct documentary connection to one of the great names of Victorian horticulture.
What it doesn't automatically tell us is who collected the original material, precisely where it was collected, or whether today's horticultural Argyraeus represents one continuously propagated clone descending from it.
We don't need to turn a documented Veitch connection into a bigger provenance story than the evidence supports.
The paperwork is already interesting enough.
So what can we actually say?
Quite a bit.
Argyraeus isn't simply a modern name someone recently invented for a silver-patterned Scindapsus. The name has documented nineteenth-century roots.
The botanical record documents Pothos argyraea J.Veitch f. in 1859, followed by Scindapsus argyraeus (J.Veitch f.) Engl. in 1879 and Scindapsus pictus var. argyraeus (J.Veitch f.) Engl. in 1898.
Modern taxonomy accepts Scindapsus pictus and places these historical Argyraeus names within its nomenclatural history and synonymy.
What remains less certain is the bridge between that botanical history and the plant circulating under Argyraeus in modern horticulture.
And perhaps that's the most interesting part of this case.
Sometimes the mystery isn't whether a name has history. Sometimes we have plenty of history.
The mystery is whether we can follow the plant itself all the way through it.
Case status: Still open.
Because apparently even the one with Victorian paperwork couldn't make this easy for us.

Sources behind this File
For the nomenclatural history in this episode, we checked the International Plant Names Index records for Scindapsus pictus, Pothos argyraea, Scindapsus argyraeus and Scindapsus pictus var. argyraeus, together with Plants of the World Online at the Royal Botanic Gardens, Kew.
The historical record there points to Hasskarl's 1842 publication of Scindapsus pictus, James Veitch Jr.'s 1859 Pothos argyraea, Engler's 1879 combination Scindapsus argyraeus, and Engler's 1898 combination Scindapsus pictus var. argyraeus.
IPNI and POWO currently give different publication citations for the 1859 name. We've therefore retained the author and year on which they agree while making that bibliographic discrepancy clear.
The evidence establishes the history of the name much more securely than it establishes an uninterrupted provenance for every modern horticultural plant carrying that name. We've deliberately kept those two questions separate.

A note on our role
Variegated Greens does not present itself as a botanical, taxonomic or nomenclatural authority. The Scindapsus Files are explorations built from the best documentation and evidence we can locate at the time of writing.
Where the historical record is clear, we try to say so. Where evidence is incomplete, conflicting or circumstantial, we try to make that equally clear.
We welcome primary-source documentation, corrections and additional evidence, and these Files remain open to revision when better information becomes available.
