I just noted the posting by @Terry Phillips of Eriosyce esmeraldana at Appreciation: - Eriosyce esmeraldana, and now I wonder if that's the name of my cactus. I was given this plant almost 20 years ago, only recently thought of wanting to know what it was, when I saw another posting about a misshapen cactus and wondered if this was supposed to have a globular shape. It's at a window but next to my computer, so I keep the blinds turned to keep the sun off the computer. It has flowered, though not for the past several years, when I've kept the blinds more closed than previously. Flowers were pale yellow, if I remember correctly, not a sure thing.
No, it is far too big, long-stemmed and branched, is is most likely a Mammillaria. I am not familiar with all of the hundreds of Mammillaria species, and the plant is etioliated, which complicates identification. Looks a bit like M. polythele, but it has pink/red flowers, AFAIK.
Definitely not what I have for the first couple years I wasn't even sure if it was still alive smaller than a match head took years to grow it the size of a quarter and less than a inch tall normally not even that tall but being over fertilizing & watering with different climate they are naturally more button shape
I want to add a link here to some distinguishing features of Mammillaria that @mandarin provided in another thread. Identification: - Mystery cactus
