I am not sure how to list my plant. I have 2 names. E. subdenudata and Echinopsis dominos. I would like to add it to the plant file, however, as it is not in there. Could you help me list it properly so that I may share it with others? Here's 3 pictures of it.

Information:
It is presently 3 inches tall by 5 inches around. Will not get much bigger. It likes a 60% sun and 40% shade, warm climate as I am in 9B, needs little to moderate water, excellent drainage and deep dry in winter. Blooms once in the year and mostly at night. Blooms last 1 to 2 days typically.

Here you go -
Barbed Sea Urchin Cactus (Lobivia ancistrophora)

It's a syn., the above is it's most recent classification.
Welcome to the site...
by the way, nice pic.

Hi AgaveGirl1
Welcome to All Things Plants. Beautiful bloom on that tiny Echinopsis.

Thanks guys

Really glad you like my little Echinopsis. It was a BIG surprise when that happened. It was also the very first bloom I ever had on any of my plants. My garden is very young as I lived in my new home less than a year.

I'll make note of its most recent classification. I stink at Latin names but notice I do have some things that aren't in the plant files. Not knowing Latin names or taking for granted what's on the container I guess doesn't help when it comes to adding to the file. I try.

Hi @AgaveGirl1 to All Things Plants from me too!
I don't know much about cactus at all but those are lovely photos of your plants ... I especially love your database photos of that Golden Barrel Cactus!

If you are ever unsure of a plant's scientific name, don't hesitate to ask. We have some really knowledgeable and helpful members here on site ... they've been a tremendous help to me many times!

We have a Plant ID Forum: http://garden.org/forums/view/... that is very helpful too and generally someone will recognize a plant very quickly and be able to give the name of the plant in question.

Again, Welcome to the site!

Welcome to ATP, AgaveGirl1! Nice photos!

This is an older post but I wanted to respond because I just submitted an "add a new plant" for the variety Dominos. As far as I can see, it's called Echinopsis ancistrophora "Dominos" because the white on the areoles is more clustered together into little spots (like dominos the toy/game).

I found Dominos under two different species names when I searched.
I found a comment on this site that Echinopsis 'dominos' and Echinopsis subdenudata are the same species. http://cactiguide.com/forum/vi...

"dominos' is just a form with more woolly aeroles. Altman no doubt love to make up names for plants, so they seem more exotic or something. I'm fairly certain it's just a sales tactic."

How do you determine when a listed variety is a sales tactic? I'm curious where that line is drawn.

For example, there are a million kinds of daylilies being marketed that can look superficially very similar.

Daylily cultivar names are registered, and even the ones that can look quite similar have different parents and therefore are different plants.

I can't find an Echinopsis cultivar registry, and even the link you have provided on your new plant proposal does not enter the name in single quotes, which usually signifies that it is a cultivar name. The link lists it as "Domino Cactus-Echinopsis Dominos." No species listed, no single quotes enclosing Dominos, and the use of Domino as a common name. You have entered an Echinopsis species (Echinopsis ancistrophora) as the common name and 'Dominos' as the cultivar name, but your link doesn't support your proposal.

Gotcha. I didn't mean to speak specifically for Echinopsis ancistrophora "dominos," although it did seem like that. I just mean in general because I don't always understand where the line is that makes any given plant a named "variety" verses a sales tactic given that most don't have registries or databases. From your answer, am I correct to understand that you're saying you don't, too?

In cases where there aren't registries or databases, I rely on Internet searches. If the name is identified as a cultivar (by being enclosed in single quotes) on many websites, I feel I can safely assume it's a known cultivar name. If it's used mainly as a common name (Domino Cactus) for plants of different species, I assume it isn't a cultivar name. I'm going to decline your new plant proposal. You could submit a name edit proposal to add Domino Cactus as a common name to the species entry.

It is a commonly available selection of what used to be E. subdenudata. Just like another: E. subdenudata 'Fuzzy Navel', which was released by the Huntington as part of the ISI plant introductions:

http://www.huntington.org/bota...

From this description the link to E. ancistrophora does not to appear extremely certain...

I have both and it is unclear to me what is the difference between Dominos and Fuzzy Navel. Supposedly Fuzzy Navel has more wool on the areoles, but my plants were equally woolly and as they grew bigger both started loosing that really woolly appearance. I have some seedlings of Fuzzy Navel that look really woolly at the moment. Flowers are the same as well, so it feels like this might just be a sales tactic. I think that Domino or Dominos might be an Altman's plant introduction, which makes it possible they just changed the name to have something 'new' to sell, or that they actually selected a specific plant and brought that into production that is similar enough to be hard to distinguish.

No, I actually think it should be declined. I submitted it because one of the plants I got was listed as "Echinopsis subdenudata 'dominos'" but if that were the case, it should have been "Echinopsis ancistrophora 'dominos'," anyway.

Internet searches seem prone to so much error. But I guess it's the best/only guide there is. Another member and I have been breeding our own strains of zinnias for years. I wonder at what point those would be listed as varieties, if we sold them and listed them for sale?

I don't think I'll ever sell them (I'd rather give them away) or list them, but both of us have lineages which are clearly and obviously distinct from any mixes or cultivars available to the public. So that's where my mind goes when I think about how you determine what is or is not a variety of any given species.

The only problem when you add your new question to an existing thread is that the OP will get getting alerts for each of the new posts. Some folks don't mind, but some do. It may be better to start your own thread.

I actually couldn't figure out how to post in this forum at first (but now I have) because I was on the wrong place. Sorry, @AgaveGirl1!
