Tillandsia guenther-nolleri
From Mexico.
Peter Tristram 01/11.

Peter Tristram ... "T. guenther-nolleri is a relatively recently described Tillandsia. Its story is quite interesting (see Derek Butcher's dvd) and I wonder whether I have the smaller form as this one was only 1m long when it bloomed. The petals are an interesting burgundy and cream colour."

Peter Tristram ... "This is a big species in the sense that the spike is 1.5m tall as is the spread of the plant. This one came from Pam quite a few years ago and is somewhat larger than what Lydia sells as guenther-nolleri, which was suggested could be a natural hybrid, though it just looks like a more compact version. This one matches the habitat photos very well too. Unfortunately I missed the flowers which were slightly light greyish purple from memory. I think I posted pics of Lydia’s plant a year or two back.
The pic (on left) is another plant I have obtained as this species from Lydia (twice now) which certainly doesn’t match too well. It is also slightly caulescent and could well have been collected in the same area. The flowers are very similar to those on Pam’s plant too."

Previously in March 1990 Gunther Noller had collected a smaller, not yet flowering plant at the same location. The same Tillandsia was collected by Jurgen Lautner, Gottingen, in 1992 and 1994.
The plant usually grows terrestrial (seldom on cactus), in dry scrub with Cereus, Cephalocereus, a cushion-forming Mammillaria, Barkeria dorotheae, T. marabascoensis, T. ionantha, T. makoyana, and T. caput-medusae.
The plant gets its name from our friend Gunther Noller, from Bischmisheim near Saarbrucken, who discovered this Tillandsia in the Spring 1990. Gunther Noller makes field studies in the area of tillandsias, orchids and cactus, on many trips to south and Central America. We ourselves have traveled Mexico, Ecuador and Peru with him.

The plant differs from T. roseoscapa Matuda in the following points:
Plant only forms short stems.
Leaf internodes larger, leaves more hard leathery, more than twice as long, forming a lax rosette.
Scape flexuous, cape bracts much longer, hard leathery with a sharp tip,
Spikes much longer, (to 20cm instead of 3-10cm), however more narrow and lanceolate linear, long stemmed.
Floral bracts not keeled, almost glabrous, sepals wider, glabrous, petals longer, bright violet instead of yellow green.

The plant is not only conspicuous through its size. It is not like any other Mexican Tillandsia and is therefore hard to classify. The closest seems to be T. roseoscapa Matuda however this is, so far, only known from southern Mexico in highlands over 1000m. In contrast to the description by Matuda or Rauh, where the stem is said to be short, the front part of the plant often forms in the course of years a stem many meters long, whose rear end rots, continuing to grow over the rocks. When flowering it forms an approximately 80-120cm high rosette.
Near Zapotitlan close to Tehuacan, Estdo. Puebla, we saw plants to 10m long with rotten stems (EM 911803). In the state of Oaxaca near Coatlan the plants were smaller and formed dense clumps, 25cm high plants flowering already. In contrast to the statement by Rauh all of our material showed the filaments with the anthers protruding far from the flower tube.

Already in Die Bromelie 2/91, we reported on our trip "10 years of field examinations on the Mexican Pacific Coast" which reminded us of this unusual new Tillandsia. We had looked for the location on our trip in February 1991 on the basis of advice from Gunther Noller. Already on the basis of the photographs of smaller plants, we knew what unnamed plant we were looking for. Gunther had brought us two plants and reported that he had been unable to find a single flowering plant. We now had great luck, in the following year to find several flowering examples of the species, unfortunately these proved to be much too large for transportation. Not one of the examples could be fitted in our large suitcase. Two inflorescences, that only some weeks before had been in full flower were stowed in the suitcase diagonally and packed two extra, almost flowering size plants. The suitcase was full! From now on we were limited in our collections because we had no more space for large plants!
We hoped that one of the larger plants would flower in our collection soon. They received the best place in the sunniest position under the roof of our glasshouse where they made themselves comfortable and grew well.
In the Spring of 1993 they were so large that both plants developed an inflorescence. But our curiosity was put to a long test: only in July were the plants large enough and we finally saw flowering. In the autumn, the mother plants produced three strong offsets each.
In March 1994, we went to Cihuatlan again, and although I had high fever and was feeling awful from the antibiotics that I had taken, we drove to the location. We arrived at 10 o'clock in the morning with the temperature at 35C degrees in the shade, and humidity at 46%.
I pulled on my thickest jeans and a long sleeved shirt and struggled through the thorn bushes up the mountain. There was a reasonable path because the local people hunted iguanas there. In our last trip we saw two boys, who watched us warily because they did not know who we were, soon killed two animals. On the coast, today hundreds of living and dead iguanas are offered for sale. Especially cruel is how the mouths of living animals are secured so they will not bite. – no animal welfare organisations here.
Despite the path, I was burning hot as I silently moved through the narrow thorny path. My heart thumped alarmingly. Only the romantic outlook of the Rio Marabasco, far below, winding through the misty heat haze makes the toil seem worthwhile. I found not a single plant and not even a plant of the new T. marabascoensis, that had been found there by Jurgen Lautner. Strangely, from the really large plants that we saw there in 1991 in full flower, should have produced offsets. But precisely at the same area I found not a single one. Quite distressed I returned to the car only to find the temperature was 4C degrees higher. The plant is clearly not abundant. Jurgen Lautner had luck however in 1994 when he found some plants again.
