Thank you Peter! Call me a nerd, but I love learning those definitions and how they apply to ecological niches.
I was trained in zoology to recognize traits that hinted at lifestyle, but sadly never took botany that taught me the same. Always happy to find sources to learn from!
All these new species are exciting!

Hi Cory,
Streamlined leaf blades are widely associated rheophytism and with aquatic plants - indeed before the term 'rheophytism' was coined by van Steenis, Ridley, who termed it ‘stenophylly’, mentioned the ecological nice and its adaptations in "On the Flora of the Eastern Coast of the Malay Peninsula - [Transactions of the Linnean Society of London. 2nd series, Botany 3(10), 267-408].
By the way, the "wider" leaf blade in the image is an undescribed Aridarum, also a rheophyte, and these blades still classify as narrow.
This is a nice paper dealing with morphological adaptations associated with rheophytism:

Kind Regards

I find the long, thin shape of the leaves reminiscent of some of the Cryptocorynes that are found in faster flowing water, is this also the case for this plant? I would guess to reduce drag and not have the plant ripped from it's spot in fast flow (compared to the wider leaved plant in the habitat photos, that may find itself taking a trip downstream!).
Best, Corey

Peter, these are all amazing plants!!
I need to grow some rheophytes, I think!
