- lepidote => 11
11. Inflorescence - simple => 12
- bipinnate: Leaves channelled, regularly lepidote with coarse cinereous scales, inflorescence with up to 8 spikes which are laxly 3 - 4 flowered, the posterior sepals carinate, 1/3 to 1/2 connate, lithophytic growing at sea level => brachyphylla
12. Inflorescence - with polystichous flowers => 13
- with distichous flowers: Plant ca. 4 cm in diameter, short caulescent, small pine cone shaped, pendant, leaves grey appressed lepidote => reclinata
13. Leaves - secund, thin and soft, grey with appressed trichomes, looking like grey velvet, scape densely lepidote, inflorescence simple, sometimes compound of up to 3-flowered spikes, floral bracts carmine-red, sepals slightly lepidote, free, posterior ones carinate, petals violet-rose => heubergeri

16. Plant - 2.5 to 5 cm in diameter, rosette of broadly triangular leaves with shorter blade, very densely and regularly silvery subpruinose lepidote, appearing like silvery velvet, sepals carinate and short connate, lithophytic 1800 - 2200 m => organensis
- Plant bigger, up to 15 cm in diameter, rosette often bulbose, leaves grey - green appressed grey lepidote, appearing like grey velvet, bipinnate with 1 - 3 (-5 ) flowered spikes, floral bracts conspicuously carinate, posterior sepals carinate, epiphytic => roseiflora
Comments:
The plant is extremely rare and there are only few examples represented in collections. It is relatively common in its natural habitat, the rock walls however are often hundreds of meters almost vertical and so the plant is well protected from the collectors.
The plants with the name T. brachyphylla currently being grown are likely to be some other small wrong named tillandsias. Another name which has been confused with T. brachyphylla is the so-called T. regnellii which is going to be called now T. roseiflora. "T. brachyphylla" in the second edition of the book "Bromelien" by Werner Rauh and in the Journal of the Bromeliad Society, July /Aug. 1980, title page (photograph by Werner Rauh) and on page 13 of "The Colourful Bromeliads" by Victoria Padilla is in fact now T. roseiflora.
