Philodendron stenolobum

This specimen of Philodendron stenolobum is the one that I used for my original cross of P. bipinnatifidum (aka selloum) and P. stenolobum. This is not the most desirable type, as I have seen much narrower leaf blades on other varieties.

P. stenolobum was being marketed as "P. williamsii" years ago when I did the cross that I named "Philodendron x willoum"; since then, the confusion has been cleared up, at least for me, because I have now a specimen of the true P. williamsii. Of course, I have done hybrids using the true P. williamsii.
