Anthurium scherzerianum (the typical form).

These photos show the most probably a cultivar, too (or even some),
but the mostly approximating the botanical species.

The leaves are leathery and relatively narrow.
The red or sometimes orange spadix is always tortile.
A week after during the bloom the male flowers start to pollen.
