this is 4 diff sizes on a branch
cliff

and this is a clump
Have 5 of these and the plants are from 1" to 7"
The site also says Variabilis doesn't grow in clumps, that they are single plants

gonz might can answer this one best. Flowers will tell all also.
Here is a great sight to start researching any bromeliad.

Here is a link that might be useful: Bromleiads

It looks like Adpressiflora. I find all the sizes you show growing in the bush in the Bahamas.

Kim,
Don't think it is Adpressi. It doesn't show it growing in Fl. I goggled the pics and it looks a lot different in growth & shape. I have another Variabilis and Utris coming shortly from another source,. will check them side by side when they get here.
Thanks--Cliff

The heftiness of the plant leads me to say T. fasciculata as T. utriculata has longer leaves and is not quite as bulky.

Gonz,
I have at least 2 for sure I bought a red spike a yellow spike and a y & r spike maybe 3 different Fasciculatas the bases on the fasci's look more loose than the 1 i'm trying to id
the 1st pic the pr on the left are fasci and the plant on the right is my noid it has a normal looking base
cliff

this is my largest bluish fasci the leaves are shaped different and at the base the leaves are not as wide as on the Noid
which has a sharp drop in width about at the halfway point
of the leaf and on the Fasci has a continual drop in width size
to the tip
.the smallest plants in the clumps are really grass like
cliff

Cliff,
Your right. I looked further. The local botanist shows this as t. Utriaculata. Check out http://www.levypreserve.org. utriaculata are quite stiff and leathery. And get big, a couple feet across like this guy. Yellow spike.
Kim

Kim, T. utriculata has a many-branched green inflorescence, very tall yet not showy. The T. fasciculata complex has inflorescences that range from red to yellow to almost orangish. T. utriculata can get up to 3' across while fasciculata will be smaller.
