Alcantarea is a large brom, over a metre tall, which is what you are showing on this link. This picture is of Billbergia nutans, a small plant with blue, green and yellow flowers on a pink stem. Common name 'Queens Tears'. So, yes, not correctly named. 🙂
@Sussanah not sure what the one without the flower is. The pink flower is Billbergia nutans, without doubt. The Alcantarea has a long spike over a metre tall in a metre plus tall brom, commonly with silverish leaves.
