I just received another request for information about an "extremely rare" Philodendron sp. known as "Philodendron barryii". I usually receive two or three each year. A few people love to sell this supposedly "rare species" on eBay. I'm not sure who started this name, or why they selected that name, but "Philodendron barryii" does not exist in taxonomy. You cannot find it on TROPICOS (a service of the Missouri Botanical Garden), GRIN, ePIC (a service of the Royal Botanic Garden Kew in London), in any of the journals of noted aroid botanist and Philodendron expert Dr. Tom Croat, in any recognized aroid text, or any scientific source. One lady who wrote to me insisted it was "extremely rare" and almost no botanist knew of its existence. That would be really strange since botanists are the people who give plants their names and publish their work in some scientific journal. Collectors give "common names" to plants, and that is likely what someone did to this species. If it really has the name "Philodendron barryii" it has to have been published somewhere! And sources like the International Plant Names Index (IPNI) and the ones named above pick them up quickly. And for certain, some aroid botanist would know the name! It is likely that someone, somewhere, decided it would be neat to have a plant named after themselves. I'd bet that person's name was Barry! And once a name gets started all sorts of trusting people just use it, they never check the botanical sources to verify it exists. I run into them all the time with plants such as "Philodendron glaucophyllum", "Philodendron wilsonii", and many others. None of those are real botanical names either, but they are commonly used. As Dr. Croat says, "they are simply made up". I can't find a lot of talk about "Philodendron barryii" on the web, but one garden site does have people who love to identify Philodendron sp. with multi lobes as "Philodendron barryii". The plant sold on eBay as "P. barryii" is almost certainly Philodendron radiatum. Now, I know some will say "OH NO", "Not Possible". "Philodendron radiatum does not look like "P. barryii". And "Philodendron barryii is a new species". Well, Philodendron radiatum has at least 10 known growth forms! The blade changes constantly as the plant matures. It is variable and has at least two known adult forms! They don't always look alike, and scientists have known that for more than 100 years. But they always produce the same spathe and spadix (inflorescence), thus they are the same species. People just have difficulty accepting that concept in botany. The common believe seems to be, if it looks even remotely different, it just has to be a different species. And that is simply not correct. Just a bit of explanation. We all know people who are big, people who are small, have short limbs, long limbs, are obese, dark skin , light skin, red skin, yellowish skin, whitish skin and numerous other variables. But every one of them is a Homo sapiens, a human being! People are variable, and so are many plants, especially aroids. And Philodendron sp. are aroids. Philodendron hederaceum has at least 20 published names! For many years botanists would go intot he field and find the velvety Philodendron with a different sized blade, or slightly different color and texture, and give it a new "scientific" name. After a great deal of research it was discovered there was only one species! So all those other names are now considered synonyms. Yet, people still love to use names like "Philodendron miduhoi", "Philodendron scandens" and lots of others. But sorry, the base species is Philodendron hederaceum. The others are simply synonym names. If you are convinced you are growing "Philodendron barryii" you are welcome to use that name, but it is simply a common name. It is not scientific! Here's a lot more information if you are inclined to read it: http://www.exoticrainforest.com/Philodendron radiatum pc.html But sorry! "Philodendron barryii" is not rare. It does not even exist, unless of course you call it Phildoendron radiatum! Hmm. I wonder if I could get away with naming some plant "Philodendron steveii"?
