Tillandsia scaposa
Formerly T. ionantha var scaposa, then "tangled" with T. kolbii, now species status T. scaposa.
Now considered NOT the same as T. kolbii.
Derek Butcher ..."40 years ago everybody knew what a T. ionantha looked like and if you were lucky you may have had a T. ionantha var. scaposa, which needed more shade than your tough old T. ionantha and came from Guatemala. The other difference was the inflorescence, which is nestled in the leaf rosette for T. ionantha but raised for the variety scaposa."
Please see articles and pictures of T. ionantha, T. kolbii this website.
Particularly note Detective Derek's article DD0511
and DD1008 "Natural Hybrids" for the T. kolbii connection.

Chris Larson ... "The first is what I would call a typical Guatemalan T. scaposa, the second is a more solid form with thicker, greener leaves."

Andrew Flower ... "My Tillandsia scaposa Zebra Stripes is flowering nicely at the moment - two of them developed in a batch of 400 seedlings that resulted from crossing some T. scaposa seedlings I got from Pam Koide in 2000. The variegated pair flowered in 2012, and have carried the leaf form over for the succeeding generations of offsets.
Compare the varigations on the T. scaposa to the variegated Tillandsia aeranthos pictured here. Looking closely at the T. scaposa, the variegated effect is caused by patches of cuticle where there are no trichomes laid down, giving a rather haphazzard effect. The T. aeranthos variegation is quite different - regular bands on the leaves where the colour of the cuticle changes (and trichome development is maintained albiet slightly reduced in places).
I have crossed between the two Zebra Stripes T. scaposa a couple of times, and there were no stripy seedlings resulting. I have also crossed a variegated T. aeranthos with another variegated T. aeranthos, and 54% of the seedlings were variegated. Appears that the stripy effect on T. scaposa is not sexually heritable whereas the variegations on T. aeranthos are (although the seedling population was far too small to make the percentage statistically informative).
Inclines me to the view that old Zebra Stripes has fake variegations!"
Derek Butcher ... "Interesting that this coincides with a plant brought in to the Oct meeting in Adelaide.
Talking of labels, it was great to see Tillandsia ‘Zebra Crossing’ almost in flower brought in by Ian Cook. There are not many around Australia and harks back to 1981 when I collected seed from a Tillandsia aeranthos and sowed it on a piece of cork. I assumed that it was self–set but as I have never seen seed on my various T. aeranthos since I now think it must be the proverbial milkman!
Anyway, said seedlings grew but slowly and I selected one that was different because its leaves had dark, almost black, cross banding just like a zebra crossing. In 2002 (21 years later) it flowered and I registered this oddity."
