I'm inclined to think the bulb plant is an apongeton, although my experience with a nattans was a bit different - the leaves were more crinkled and grew upwards. Mine grew like crazy, to the point where it was hard to trim and maintain a decent appearance, eventually taking over the tank and forcing me to remove it.

Here are some more pics of the bulb.

I've been going over the possibilities in my mind and I think I might have finally pinpointed the species. The plant that was eluding me earlier is Barterraca longifolia - it's a strong contender, if not the actual one. There are two forms of this plant, a green and a red variant; given the photos, I'd say the green form is a good match. The characteristics seem to align: a fleshy rhizome, rosette leaf arrangement, and undulate margins. I'm not ruling out other possibilities entirely, but Barterraca longifolia is definitely a prime suspect.

Given the leaf veins, rosette form, and what seems to be a rhizome in the substrate, it shares characteristics with Echinodorus. However, I must note that the taxonomy of this genus is often confusing, with numerous artificially cultivated varieties stemming from naturally occurring species that were likely misclassified to begin with. I recall having a similar plant that initially had leaves almost flat on the substrate, but it has since grown more vertically; unfortunately, I've lost track of the tag name.

As for the second plant, which seems to be the mass of runners on the wood branch, I'm not quite sure what it is. I've had little success with carpeting plants, which this might be, or something similar.
Color seems to be the main difference. I have the red form and my leaves are around 6 inches long now, but the stem is relatively short, only 3/4 to an inch. The op's plant has a noticeably longer stem portion.

The bulb does look similar, though. My apongeton bulb was more onion-like, similar to my crinum.

After re-examining Kasselmann's book, I found that the single species of Barterraca longifolia occurs in both red and green forms, which she refers to as cultivars. The main difference between the two is the size, with the green form remaining somewhat smaller.

Regarding Aponogeton species, they all have a tuber, with one species having a thin rhizome. My personal experience with multiple Aponogeton species, as well as my red Tiger Lotus, confirms this characteristic. The roots of these plants are notably thinner than those in the provided photos, but I'm unsure of the significance of this observation.

I think it's an Aponogeton. I've had a Nattans before, and the leaves were really crinkly and grew straight up. Mine grew super fast, but the leaf shape was a pain to trim and it was taking over my tank, so I ended up pulling it out.

Thanks for all the replies, I really appreciate it. I've been reading through and I think we've narrowed it down to Barterraca longifolia and Aponogeton sp. I checked out some pictures of Barterraca longifolia, and while it does look similar, the leaves seem a bit different - they're straight and wavy, whereas mine have a bit of a curl to them.

I'm thinking the best way to figure out what it is for sure is just to wait and see what happens. If it sends out shoots to the top of the aquarium and flowers, that should give us a better idea. Either way, I'm happy with the options - both plants seem pretty cool, and I'd be happy to keep either one.

Thanks again for the help, guys.

This plant's growth rate is crazy - about a leaf (or two) daily. The more I look at it, the more I think it resembles Aponogeton crispus. I may need to rethink its placement, as it's currently a nice focal point, but if it is indeed Aponogeton crispus, it's going to get massive.

I'm back to my initial thought after seeing this photo - this could indeed be an Echinodorus species. The "bulb" appears to be the rhizome, which in these plants can be quite substantial. I have one in my 70g, but unfortunately, I've misplaced the tag and can't recall the name. My Echinodorus has also pushed itself above the sand, so that's another similarity I've observed.

I think I just need to be patient and wait for it to flower then.
