Bruce Dunstan ... "The plant grows at the type locality epilithically on low rocks in large groups together with a green mammilaria with long brown or black thorns. On nearby bushes there is a very large form of T. atroviridipetala with small appressed scales."

Dale Dixon ... "T. capistranoensis (subg. Tillandsia) is a lithophytic species from Mexico. The type specimen was collected on the road between San Juan Capistrano and Jesus Maria in the State of Zacatecas at 2000 m elevation.
The specific epithets is in reference to its location. Whenever you see the suffix -ensis it means from that place ie from San Juan Capistrano.
My plant is suspended on wire and hangs in full sun on the outside of the Tillandsia House."

EHLERS in Rauh spicis longius stipitatis, bracteis florigeris densioribus rhachidem celantibus, percarinatis, viridoflavis, sepalis aequantibus vel brevioribus, sepalis coriaceis, longioribus et subliberis et petalis malvaceis nec violaceis recedit.

Habitat Mexico, State of Zacatecas, on the road between San Juan Capistrano and Jesus Maria, 2000m.
The plant grows at the type locality epilithically on low rocks in large groups together with a green Mammilaria with long brown or black thorns. On nearby bushes there is a very large form of T. atroviridipetala with small appressed scales.
Habitat and range: Outside the type locality a plant was found by Alfred Lau, in Cordoba, near Angustilla in the neighbourhood of Huazamote (border between Durango and Nayarit).
The plant belongs to the complex around T. polystachia Linnaeus, and also T. mazatlanensis Rauh and T. durangensis Rauh & R. Ehlers.
Differs from T. mazatlanensis in
1. Plant saxicolous not epiphytic.
2. Leaves sub-succulent, greyish white.
3. Spikes wider and longer, stemmed.
4. Flower bracts yellow and keeled.
5. Sepals longer and sub-free.
6. Petals mauve not violet.
Differs from T. durangensis in
1. Spikes longer stemmed
2. Flower bracts more dense, covering the rhachis (not visible) at flowering, strongly keeled, yellow (instead of carmine red) or green, as long as the sepal or shorter.
3. Sepals hard leathery, longer and sub-free.
4. Petals mauve, not violet.
