Tillandsia juerg-rutschmannii

Dale Dixon 10/18 in habitat
Peter Tristram 10/18. with Eric Bak

Dale Dixon ... "Iím not sure if youíre aware but Iím on a OS trip through Mexico and Cuba. Currently in San Cristůbal. Yesterday we cruised down the CaŮůn del Sumidero. I was expecting to see Tillandsia so here they are:

2 & 3 Tillandsia juerg-rutschmannii clinging to the walls high above us. In some areas they were near water level. Is this species available in Australia? Stunning plant.
4, 5 & 6 Tillandsia ionantha not sure of variety. Very close to water level. Iím sure it would get covered during flood rains. Interesting!
There was also Tillandsia schiedeana and Tillandsia caput-medusae. Enjoy."
Chris Larson ... "Good to see the photos. T. juerg-rutschmannii is around. Not common, but it takes a while to get to size. Great plant to grow.
The ionantha would be T. ionantha var van hyningii. Not on the disc as coming from Sumidero Canyon, but Iím pretty sure Iíve read that it does."
Peter Tristram ... "Indeed, T. juerg-rutschmannii was imported a couple of times from collections in Europe. As far as I know only one clone now survives, one from Heidelberg BG, unless a collector was lucky enough to score one from the other sources. The plant I obtained from Peter Bak in the images (check the pics closely!), I gave to Bruce to feed, which he did, resulting in a bloom but I think it died without pupping. Chris Larson, in Melbourne, has also bloomed one but I think itís a sad tale too! I find it a slow grower so maybe one day itíll become more available.
Another to check on the dvd is T. yutaninoensis, sort of like y-r on steroids! Itís a very different looking plant though, more like mirabilis, parryi, ulrici and other large Mexican lithophytes.
Propagation of these lithophytic Tillandsia species (from both continents) invariably relies on removal of adventitious pups and often these are only produced when the plant is fairly small, so mounting plants works well but is slower than potting up which allows for root feeding. Lots of air and light around the base, with a loose mix so as not to rot pups, are essential."
