Duvernoia - related to Justicia, endemic to
Africa, particularly Zimbabwe.

It's in the database here:

Justicia potarensis

(the single species in this genus is currently classified as a member of the genus Justica)

thanks ! I felt like it should be, but repeated sources dd not indicate so.

I have, in the past, asked the admin what verification sources she uses, but never got any answers.

I would appreciate others' opinions.

The ATP database oftentimes does no pull u anything, even when apparently, it is there hiding the whole time.

There's some question about the correct spelling. Catalog of Life spells it Duvernoya and The Plant List spells it Duvernoia. In both cases, however, all but one of the species have been reclassified as synonyms for Justicia species. The only exception I could find is Duvernoya pumila, which is a synonym for Dicliptera pumila. I found no accepted species names for Duvernoia or Duvernoya in any taxonomic database.

That is one of those questions that would seem to have a simple answer, but doesn't.

As far as listing accepted species names, we generally use the Catalog of Life (http://www.catalogueoflife.org...), which itself is a compilation of a number of different databases. As an example, the Catalog of Life uses the Integrated Taxonomic Information System (itis.gov) as its source of taxonomic information on North American species. ITIS, in turn, derives its information from a large number of different sources.

Like anything related to computers, it doesn't do a great job of guessing a person's intentions. Misspelling a plant name, for example, can greatly reduce the chances of the search engine finding what you are looking for.

Opinions on what?

Opinions on what you just answered.

I totally agree about spelling and entering correct info to begin with. Machines are not more intelligent than humans.

I am not justifying anything, but many things are misspelled on the web, and if cut and pasted , transfer that error. I always try to find at least sources for the same term before mentioning it. But one must consider the sources.

My preferred sources are USDA,, wildflower.org, floridata. I find RHS difficult to access. But no database is totally infallible, including ATP nor ATP's elder sibling.

And I am no more correct than anyone else, we all have a variety of useful knowledge and wisdom,
which IMHO, can be shared for the benefit if all. NO ONE should be made to feel inferior. Intelligent people know that curiosity is a good thing and should be encouraged.

If anyone has been patient enough to read this through to the end, I will reveal this, not for pity, but perhaps understanding: I am legally blind.
I can spell perfectly well, but sometimes things look correct but aren't. I try my hardest to make sure not to make errors, but stuff happens !

If anyone opines that I don't belong here, just say so.
I can continue to contribute elsewhere.

Count your blessings, I pray you never have to be challenged. It is a major pain. But I am blessed in infinite ways. I bid you peace and joy.

Nothing wrong with wanting the database to be as complete and accurate as possible. Although, from what everyone has posted here, it sounds like even the "experts" out there don't agree. Which is why there are lots of synonyms in the database.

You have my sincere sympathy in dealing with vision problems, Lavanda. I have nasty eye problems and was legally blind in one eye at one point. A wonderful doctor was able to help with that, but reading is still difficult.

Hope you decide to stick around.

Thank you Woffie and everyone else who has supported me, I never want to be a troublemaker !

But here is the next question: where do we report an incorrect synonym ?

Go to the plants page in the database. Scroll down to the bottom and under the heading Edit Actions:, selected Edit Plant Name. You can make changes there. After you make your change click on Submit your proposed change at the bottom of the page.

And, sometimes your entry may be questioned or rejected. In that case, I've often engaged in treemail discussions with the responding Administrator and we both end up doing some research to compare and sort out what is the most accurate information available. I always learn something new from this, so consider it a win-win even when I was incorrect to begin with. Every entry is appreciated, and adds to the collaborative nature of the database. Keep on posting!
