What should I call this spineless Hechtia?

[chanin]

Hi friend, I have this Hechtia in my collection for a while. It came from US with a name Hechtia tillandsioides, but I have heard some dealer recently called it Hechtia lundelliorum and someone said it is a synonym with H. purpusii and also H. lindmanioides even H. caerulea So,which name should be true?

Could Timm or someone, help me please?

Here is my plant...a spineless Hechtia.

Hi chanin,

that is kinda funny, I do have exactly the same plant under
exactly the same name Hechtia tillandsioides.
Unfortunately from unknown orgin without any data.

Can't tell you much more, it grows well but it has not flowered
within the last 12 years

Anybody else ?

Greetings Timm
