The leaf does look like a possible match on portulacaria pygmaea (old name Ceraria pygmaea). I can't find any examples of the ridges on older growth. I think we are on the right track now. I think it's most likely a portulacaria instead of a crassula.

It never occurred to me that it wasn’t a Crassula. I have several props going. It’ll be interesting to see them develop. This one’s so gnarly and has had god knows what environmental influences that it’s hard to tell what came from what. Thank you all for your expertise and time.

No problem! Portulacaria afra is my favorite plant of all time, so I have a special interest with these types.

Do you have any photos of the props you could post? I am curious to see how they look compared to the main plant you posted.

These were the ends of four branches that fell off about a week after I got her. She was shipped from California to Pennsylvania and came out of the box intact. I about had a stroke when they fell off. It was exactly what a jade does when it has rot. They just fell off. I thought I was going to wind up with a dead mother plant and that these were all I’d have left. I just popped them into the pot and let them be. They’ve only been potted for about a couple weeks and look like hell, but they have beautiful roots so I think they’ll be fine. I put the whole family in light shade and fretted over them all summer. No more dropping but also very little growth. I brought them in for the winter and they did nothing till I decided the main trunk was cockeyed, so I took some gritty mix out of one side and wiggled it straight. Potted the props then. That was two weeks ago and there are tons of little buds popping out. Really weird, but I’ll take it.

This P. Afra came in the same box. It’s my only one but I love it fiercely.
