I can only guess that this cactus has gotten so etiolated it has lost its proper shape.

Maybe a very etiolate Echinopsis chamaecereus? On looking more closely I think not, but it's really hard to tell, since the growth is so elongated.

At any rate it needs way more sun, but move it into more sun gradually. The long skinny parts will stay the same, but any new growth should develop properly.

Where is the pic from? Can you ask the source?

Hi my house.

Try asking the person you bought it from, if they don't know ask who THEY bought it from. Also there's a place here called 'Name that Plant' but I believe the Folks here at C&S forum would be likelier to know.

Pls. allow more time for additional suggestions.

im guessing chamacereus too. Heavily etiolated. The spiral might be a tad reminiscent of mammilaria, but if you look close enough, youll see the ribs and the gap-lines in between.

Most cacti and succulents need stronger light exposure than is present in typical household interiors. Move your plant closer to a bright - as in south- or west-facing - window. Or set up a dedicated light fixture for it. If you have other house plants that appear to have the same problem maybe put together a growing area where they are grouped beneath long tubular bulbs.

It’s difficult to tell because of the etiolation, but I’m gonna throw another cactus into the mix. Maybe a Rebutia like Rebutia fabrisii or a variety of it.

Looks like a free seedling I got with one of the cactus I bought from the San Jose succulent show this year:).

Ariel, I kind of like it to, although, at the same time, it kind of makes me wince. Looks like some kind of mutant ocean sea anemone/monster plant :-)

I’m really curious to see what this cactus will like with a year’s worth of good growth. With the right amount of light will it grow little ball blobs on the tips or will the skinny parts just fill out. Maybe a littler bit of both. I would personally leave it alone, but slowly acclimate to more sun. In the end you will have a one of a kind cactus;).

I have an Echinocereus that has mealybug damage on the top growth. Now it grows little cactus out of the damaged area. It’s a one of a kind;).
