The leaves appear too narrow and pointed for Spathiphyllum Sensation, even a juvenile plant. I'd like to propose that this image be moved to the general database entry for Spathiphyllum.

I agree, go ahead and propose it.

And to answer the caption about leaves getting brown:
Most likely a combo of issues like not getting enough light and/or going too long between watering, or even overwatering, it can be difficult to judge as the pot is too large.

Thanks Sue, I just submitted the proposal ... I posted here because I'm old and I'd forgotten that we could propose moving someone else's photo.

I just checked and it looks like member rockelfraser joined garden.org a couple of months ago but has not posted on any forums; their only contribution to the site appears to be the uploading of this single image to the database.

Well generally we wait for the member to reply first but I suspect this new member posted the photo and from the caption, I'm too guessing they were hoping for some help for the brown leaves rather than adding a photo to enhance the database. Your assessment is probably correct.
