Hello everyone! A post on the Aroid Piptospatha sp."Kalimantan" is up on my blog AquaBiota! Here is an excerpt of what you'll find there, for the rest click on the link below! Thank you for taking the time to check out this post ☺ Enjoy!
Inspire91

It has been around for quite some time, but again relatively newly introduced to the hobby. It isn't the most flashy or interesting Aroid around, but it is interesting in it's own way with a bright red petiole and spade-shaped leaves with finely serrated edging. This plant does get a little on the large side reaching heights of about 12 inches, and the leaves get to about 4 inches from top to bottom and 3 inches in width.

Nice! So finally a Piptospatha really suitable for tanks? Do the roots attach to stone/wood? How would You estimate the growth rate?
There's much literature about the Schismatoglottideae (the group of aroids Piptospatha belongs to) of Borneo, so there are chances to ID the species when the plant is flowering in emersed culture.
There are also plants of other genera looking like Piptospatha, e.g. Ooia.

AFAIK, it's not a species that can be attached to anything... more like a crypt than an Anubias in that sense. I have a specimen I got from Inspire91 in emersed culture right now, though. Hoping for flowers, but no luck yet :)

@miremonster - yes it is as Asuka has stated, an aroid but more like a crypt without the tendency for random melting :) hardier I must say!

@asuka - good luck! Let me know if you have any success!

asuka & inspire, thx for the infos!
@inspire91: Are there more detailed infos about the location and also the habitat where the plant was found?
Was the plant already labeled Piptospatha sp. Kalimantan when You have obtained it? Was there a reliable ID of the genus?

I got a plant last November that was labeled Piptospatha Manduensis Kutai Timur East Kalimatan, and I'm pretty sure it's the same plant, looks pretty much the same and fits your description, except I grow mine emersed, it only has 8 leaves, with a new one shooting up that's getting ready to unfurl. It's doing really well. If I remember correctly, I put it in a mixture of shpagnum peat moss and scott's potting soil, heavier on the potting soil. Ideally I would've used some beech leaves or something like that, but I worked with what I had. I need to find me some beech leaves, that's what everyone seems to be using, or maybe they're overrated, any opinions? I also put a little selaginella I had around the base of the pot and it looks really nice, I can't wait till it fills out more! I give it an average of 12 hours of light a day, with the occasional "cloudy" day where I don't turn the lights on. Though it still gets ambient light from the room I suppose, unless it's really a cloudy day haha. Like someone else said before, it's not really a flashy plant, but I love it! Definitely a great addition to anyone's collection!

WOW very cool. Looks like an anubias but grows like a crypt. :D Has anyone had much success with it growing submerged? Also where can you buy it? Thanks

In that Japanese blog the Piptospatha sp. Kalimantan is also called P. cf. manduensis:
http://sipons.exblog.jp/tags/Piptospatha sp. Kalimantan/
As shown there, the blogger has flowered it.
I don't know if there was already an attempt to ID it scientifically, with the result that the plant can't definitely be assigned to the species P. manduensis, or if the naming as Piptospatha cf. manduensis bases on a guess only.

@miremonster - If I do get any other info on this plant I will surely share it here! :) But for now I've shared all that I know in my blog.

Really nice looking plant! If anyone has one for sale, please PM me. Have lots of Schismatoglottis/Aridarum/Bucephalandras to trade, or can offer cash.

Do You have aquarium experience with any Aridarums?, or do You keep them only emersed? I don't find hints that they can be grown under water.
Schismatoglottis: others than roseospatha? If so, also submerged?
I don't unfortunately, since I only keep my plants emersed. I have, however, given plantlets to one of my local friends who is attempting to grow them under water, and so far we have identified at least one Schismatoglottis in my collection that looks like it can indeed grow under water (Schismatoglottis 'long huriel'-- don't know species name yet). I hope to be able to determine with more confidence that it can grow under water within the next few months. I also have another Schismatoglottis species that came from Balai Karangan that looks like it can be grown in aquatic environments, based on what my source has told me, but I have no personal experience yet to back that up.

Of course, I also have Aridarum caulescens 'angustifolium' and Schismatoglottis roseospatha, which to my knowledge can both be grown under water.

Thx, that sounds interesting! I believe it's worth it to try many of these species of the tribus Schismatoglottideae in tanks (the group with Aridarum, Bakoa, Buce, Piptospatha, Schismato ...), a lot of them are rheophytes like Buce. (that would also yeld much material for writing articles)

Well, it only took me more than half a year, but I finally got me a spathe (or at least a budding spathe). :) I'm just waiting for it to open up so I can get lots of photos, then I'll clip it and preserve it in alcohol for hopeful ID. Anybody know an aroid specialist I can contact, especially one with a strong knowledge of the Schismatoglottideae?

FWIW, the spathe is a pretty pink color ('cause that's totally going to help us ID it :rolleyes:). Pics coming eventually, whenever I manage to get off my lazy bum and take some.
