Mark Supple ... "This plant I obtained from Peter in 1990 or 91 at Five Dock by memory. It's labelled Tillandsia duratii var saxitilis still have the label, this is the first flowering of this plant and the flowers to date have no fragrance, just a quick question to all. Do any duratii not have fragrance? The flowers have been out now for 2 days. The plant itself is 600mm long and inflorence is 600mm."
Ed. ... "Yes, correct identity. No, ALL duratii have fragrance, especially early morning. But being a "new" sensation, not everyone can pick the smell at first.

Peter Tristram ... "A bit of an update from the previous yellow duratii post. It is interesting that the petals change colour to violet over time and many flowers are open simultaneously – quite a show but from a distance nothing stands out (except the fragrance!). I sure hope this clone is hardier than the other and pups well. Unfortunately the gas killed a couple of its siblings when I imported them – criminal."
Len Colgan ... "Clearly, the T. duratii came from Lotte Hromadnik. I was fortunate to witness the unbelievable location in Bolivia where I was able to find all those different coloured forms of T. duratii, with petal colours including yellow, orange, brown and purple, often mixed. Sadly, all of my plants died in the heat-wave a few years ago. But at least I have wonderful pictures."

Pam Butler 03/21 var. saxatilis
Bob Hudson 06/19 ... "Here is a photo of a disappointing white flowering T. duratii V. saxatilas. The flowers came out blue tipped petals and then faded to white but the petals curled."
Pam Butler ... "Is it a hybrid with the white flowers? It looks pretty good to me."
Bob Hudson ... "No t is not a hybrid I bought this plant from George S whilst in South Africa, when he was selling a few Tillandsias before moving to Australia."
Peter Tristram ... "Interesting history of this duratii too. Most of mine are finishing blooming though a few late maturers are not far off. One is from Lotte as a ‘white’ duratii. It has very white leaves so I bet it’s a normal flowered form and the white refers to the foliage. I hope you’ve got some others to breed with it, so we might get some interesting flower in 10 years."

Peter Tristram 19/01/14 ... "This is the latest clone to bloom of the multi-coloured duratii collected by Lotte (and Len, albeit to have to leave them behind) from near Sucre, Chuquisaca, Bolivia.
They all vary in the yellow/orange and purple content but none have had white centres yet like the usual forms."
Peter Tristram 20/01/14 ... "At least Lotte has shared some clones and I now have some seed finally though this one will bloom alone only to be hybridised.
Hell, they are slow growing (and single pupping) but do bloom regularly. Assuming I can get viable seed fairly often the multicoloured duratii might be pretty common in about 30 years...
I have 2 x 15 mm seedlings from Len's seed a few yrs back. None of last year’s seed (x normal duratii) germinated. A different flower in this pic."
Len Colgan 20/01/14 ... "In case there is someone(?) in this group who has not seen any of my pictures of different coloured T. duratii from Bolivia, I have attached just one image.
It is from a different location (Comarapa) from those involving purple that Peter has shown. The ones I collected involving purple with yellow/orange looked more like T. streptocarpa, I suspect."
Peter Tristram 21/01/14 ... "Hi Len. It is interesting regarding the ‘look’ of these as they vary. A few look more like forms of streptocarpa, except for the inflorescences, with long-tapering, somewhat flat leaf blades, and others look typical duratii with shortish, rolled blades. I notice Lotte has differing locations too but all in Chuquisaca state except for the white one. Notice the altitude variation too.
These are the ones I have that survived Quaranteen (and another, the first one from 2006 that bloomed quite brown and was posted first too and looks typical duratii v. duratii, but I can’t find the data just now – pics attached. It bloomed once and gave 1 pup which I removed but promptly died then another which I wasn’t game to remove):

Bruce Dunstan 09/20 Yellow/violet
Bruce Dunstan 08/21 This year I have another clone to play with
Peter Tristram 09/14 ... "This year a couple of new forms of the yellow flowering duratii are in bloom. Needless to say I have been cross-pollinating these three different clones so that these interesting plants can be propagated from seed. Last year’s seed has just been sown so I will know its viablility very soon. So far these forms have proven very difficult from seed with most not germinating, compared to normal duratii forms that grow like weeds. Mind you I haven’t had lots of flowers to play with until last year."

Chris Larson 12/20 var saxatilis
Geoff Beech 12/20 var saxatilis
Peter Tristram ... "The fragrance of this nice yellow duratii, ex Lotte, gave its blooming on a bench away. Imagine the thrill Len Colgan had seeing the population where this multicoloured form grows, in Bolivia."
Chris Larson ... "This T. durattii var saxitilis was ready to flower before the winter hit. It sits on the fence & gets full sun from around 9 or 10 until 12 - with no overhead coverage, from rain or sun.
In May, the spike was fully developed - or rather all but the flowers. Then, with the onset of spring, the pups started developing. I thought the flowering process was over - that it had aborted. Then, approx 3 weeks ago, the flowers started popping out. I have 2 others on the same stretch of fence that are doing the same."
Geoff Beech ... "Chris: It must be something in the Melbourne water. This one has also been in spike all winter and produced 3 offsets before flowering"
Chris Larson ... "How it swaps between flowering, then to the pupping, then back to flowering, is something I don't see often in plants (or should I say notice) which are not known for readily pupping prior to flowering. I find these things are often an aberration, and don't re-occur. However in this instance it has happened in 3 T. duratii growing in this same location."
Bruce Dunstan 05/22 (var saxatilis?) "Giant Tropiflora"
Bruce Dunstan 05/22 var. saxatilis
Peter Tristram 08/22 different coloured var. saxatilis ex Lotte
Bruce Dunstan 05/22 ... "First flowering of this seedling from Barry Genn. Labelled 'Giant Tropiflora'. It has noticeably smaller and darker flowers than all the standard var saxatilis I have flowered over the past few years. The last 2 images are comparisons with var saxatilis. It looks to have flowered a little early but then I noticed another individual is also in bud."
Pam Butler ... "Bruce, do you think it could be a hybrid??"
Bruce Dunstan ... "Pam: Speaking briefly with Barry Genn, he thought it may have some affinity to var duratii.
I have a couple from him that are labelled var duratii that Pam Koide Hyatt thought looked like var duratii and they are getting much bigger and still yet to flower. They are closer in foliage form to this small one so I guess time will tell one day."
Peter Tristram 08/22 ... "A colourful form from Lotte, more like a typical medium sized duratii v saxatilis than the distinctively different yellow, violet, orange, etc. forms."

Tillandsia duratii Visiani, subsp. duratii
Tillandsia duratii Visiani subsp. reichenbachii (Bak.) J. J. Halda stat. nov. {bas: Tillandsia reichenbachii Bak., Bromel. p. 166 (1889)}.
Tillandsia duratii Visiani subsp. streptocarpa (Bak.) J. J. Halda stat. nov. {bas: Tillandsia streptocarpa Bak. in Journ. of Bot. 25:241 (1887)}.
Three taxons of subgenus Phytarhiza (T. duratii, T. reichenbachii and T. streptocarpa) create a compact complex with not so big differencies. The last two remind the miniatures of T. duratii and are here combined as subspecies.
Scales of these three taxons are similar - abaxial ones are more orbicular or regularly lobate, adaxial ones are tailed or irregularly lobed.
T. duratii subsp. duratii has a characteristic smallest central disc with regular fimbriate five lobes on abaxial scales; adaxial scales have the upper lobe ca twice longer than the others.
T. duratii subsp. reichenbachii has much larger central disc with more complicated relief. Abaxial scales are asymetric - the upper lobe is ca twice longer, the membranous edge is almost orbicular, deeply fimbriate. The edge of adaxial scales is star-like, the upper-one is ca three times longer.
T. duratii subsp. streptocarpa has both - abaxial and adaxial scales asymmetrical with elliptic membranous edge; abaxial ones are not so deeply lobed, adaxial ones are deeply fimbriate-lobate, with ca three times longer upper lobe.
Illustrated scales are the average -in all groups is possible to find many bizarre shapes. (see plate no. V).
