Looks like a Keiki which would mean it's taking on a new form of reproducing in clonel form.
a tidbit from wiki-
Keiki paste is a cytokinin hormone which induces growth in the node of a Phalaenopsis inflorescence. It should not be confused with paste or powder containing auxins, which are used to force the production of roots.
Also,
Cytokinins (CK) are a class of plant growth substances (phytohormones) that promote cell division, or cytokinesis, in plant roots and shoots. They are involved primarily in cell growth and differentiation, but also affect apical dominance, axillary bud growth, and leaf senescence. Folke Skoog discovered their effects using coconut milk in the 1940s at the University of Wisconsin–Madison.[1]
And now for waterlily viviparism. I don't think I'm getting off topic here but anyway from the days of tropical waterlily study,
Viviparous by definition is not exactly what is considered to be the case with what goes on with such water lilies so..
In their case it's a plantlet that forms just at the point where leaf meets stem, and like wise rarely in the flower which still is not a "sprouting seed" by horticultural lingo but in truth a plantlet like a Keiki in orchids. Um here's a page that sums up the term rather quickly if you get a chance, for some insight here,

it's really interesting!
There really is a lot to sort out with one such oddity.
I bet the earths poles are shifting!
siemese leafs are abit different for all intensive purposes.
Are you sending all sorts of hormones to your plant up there!? Lol
