A 2-parted spadix, with female flowers at the bottom and male flowers at the top, exuding a pretty strong and intoxicating scent, exquisite in small doses and reminiscent of a fine French perfume but intolerable if the spadix is left indoors for any length of time. Here the partition between the female-flowered bottom part and the male-flowered upper part is visible.
This species is fairly widespread, but rare. It is here at Summit Park in Panama, likely planted. Unusual for a philodendron, it is a creeper, not a climber.
