naturally forming roots around pothos?
I purchased this huge pothos plant some time ago, and they've come with these brown things that look like roots. I'm now trying to propagate them and took a few cuttings and have them in water, but I wonder if these brown parts are themselves roots and I don't need to sprout new roots before I can plant them? How should this pothos plant be propagated?
Also, why are these roots forming in plain air?
