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!

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.

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

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!

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.

To leave aside the question if the P. sp. Kalimantan / cf. manduensis belongs to the species P. manduensis or not -

there are interesting facts about the habitat of true Piptospatha manduensis.
Nakamoto shows in his blog the species in its natural habitat:
http://cryptoandbetta.blogspot.de/2012/01/piptospatha-manduensis-type-kutai-timor.html
Look at the weird pic #5: seemingly the rhizome sticks inside the rock, bulging it.

See the species description of Piptospatha manduensis in Bogner & Hay 2000, p. 207/208
http://rbgsyd.nsw.gov.au/__data/assets/pdf_file/0007/72772/Tel9Bog179.pdf
"Habitat - On travertine in river, 50 m alt."
So the plant grows on growing calcareous rock.

Great! Peter C. Boyce has confirmed that this Piptospatha sp. "Kalimantan" is indeed Piptospatha manduensis. I've linked this thread and the one with Amanda's spathe photos in the International Aroid Society group on Facebook. For those who are registered there, here the link: https://www.facebook.com/groups/157513897683600/permalink/707888432646141/

In one of the next Schismatoglottideae papers P. manduensis will be transferred to the genus Ooia. A total of 10 Ooia species (incl. 5 newly described species) will be accepted.

I'm also interested in a source of this plant here in Europe, but another thing:

Piptospatha manduensis is moved to the other genus now: Ooia manduensis (A. Hay & J. Bogner) S. Y. Wong & P. C. Boyce (2016)

Here's the revision of Ooia: http://www.aroid.org/gallery/boyce/..., supplement 138-167] - Wong & Boyce 2016.pdf
All Ooia species are rheophytes, as well as the true Piptospathas. These 2 genera look very similar to each other, however in phylogenetic analyses they turned out as only distantly related within the Schismatoglottideae tribe. They are also distinguished by some inflorescence features.
