I have had this plant for just on 2 years now. I purchased it as a seeding and it was sold to me as "Remusatia Pumila" however, I don't think that's correct. I have been hunting around and I can see that it, and its flowers, look similar to Remusatia Vivipara? But according to https://apps.lucidcentral.org/... the Viviparas leaves are half as long as my leaf.
This is the third time I have seen a leaf and it has never produced more than 1. It seems to be currently going into an earlier than expected dormancy which is why it is looking a little rough.

Could be vivipara. Whatever it is, its hard to really judge, it appears to have a bad case of spider mites

Spider mites would explain only 1 leaf ( my history with another avoid in winter)

If you look at photos of a mature vivipara at aroidpictures it is your plant. I have grown vivipara from seed in the past, but was never able to get it to that size

Here's our database entry for: Hitchhiker Elephant Ear (Remusatia vivipara) where you will find a couple of photos for comparison.

Eric Layne's photo is representative. These are actually epiphytes. They grow in habitat on trees. How most people kill them is by not getting them out of soil mix soon enough (guilty here). If you keep it potted in a container, I'd make the mix really light, airy and porous

Ok thanks all, I think it more than likely is a Vivipara. It's also very interesting to know it's epiphytic! I keep all my in door plants in a very light and airy mix, so I'm not worried about it rotting. I hardly water this one in winter.

Damn, I haven't dealt with spidermites before but I did think that could be the issue when I saw the dark spots on there, I was just going to cut the leaf off and let it go to sleep. I don't think they're the cause of the single leaf though, the last 2 times it grew it had no issues at all and still never produced a second leaf and it lived happily all season. It was moved to a different spot this year though.

The reason its nicknamed 'the Hitch Hiker Elephant Ear' is because when the berries form, they are eaten by birds and small mammals that drop the seeds later onto the branches of trees and willy nilly in other places. The seeds germinate on tree trunks and grow there. That was my plan to do with mine--eventually, then I killed it.

We have a botanical garden here that has a very large stand of these, when they are fruiting the seeds go everywhere. If you happen to be there at that time and ask, they will let you pick up berries. I'm no stranger to growing around from seed...I hybridize my own Anthuriums and have grown them from seed, as well as Anchomanes, Philodendron and ALocasia. I was able to germinate the Remusatia seeds without problem and get them up to small plants butI think I unintentionally watered them to death. I hope to try again.

Remusatia species used to be relatively easy to source here, especially vivipara which is the most common form to be offered for sale. But it seems that they have become scarce.
