Best thing to do now would be to wait on that flower stalk and get a good pic of a completely open flower. It could be that it is a short arm variety, but the capis I've seen usually only have the tentacles on the paddles, not going down the petiole like yours. There is a pic of my capillaris (Bertioga, Brazil) on this thread. post391763.html#p391763
Not a great pic, but you can see that it is a medium arm, and the tentacles don't grow beyond the paddles, which is one thing that makes me think this may not be a capi. That the seeds don't look like capi seeds is another. looking at the seed pic and plant pic you posted, they both look more like admirabilis.
However, get a pic of a fully opened flower, and we may be able to get a better idea as to what it may be.
Everything happens for a reason. Sometimes the reason is that I make bad decisions.
