Philodendron squamiferum has those hairy petioles, but I have found these
to be somewhat variable amongst different plants. Some have quite long
"hairs" that are a lightish colour on a very red petiole, especially on
new leaves. As the leaf ages this colour in the petiole slowly fades.
On my own P. squamiferum, the petiole is not so red and the "hairs" are
shorter. I have a photo of a flowering specimen at Kew Gardens and the
peduncle is somewhat less hairy than a typical petiole. P.x "Florida" is
a hybrid of P. squamiferum x P.pedatum and as you would expect the hairs
are reduced to more like nodules. Less colour too.
The prize for hairy petioles though must go to P.verrucosum, Which in my
humble opinion is one of the most attractive and desirable philodendrons.
