Peter Tristram 03/12 - "I got this pure white leafed T. lorentziana from Lotte and what a great form. It is quite large, but more compact and xeric looking. Best of all it seems to be a good grower."
"The plant originated from Burle-Marx and to Lotte via Renate, so very likely Brazilian."
Lotte's records - "Sep.97, 164, T. lorentziana, Burle-Marx 1982 - R.Ehlers, Bahia, Bras."
Len Colgan - "Yes. It is my very very best form of T. lorentziana that came from Renate. As the original was given to her by Burle-Marx, she was quite emotional about it. I reckon I have given away two offsets to members over the years. The leaves are pure white, and the inflorescence a bit different to the more common forms from other countries outside Brasil."
Derek Butcher - "Its photo is on the Tillandsia DVD. It seems this clone has whiter leaves (and more virginal) under Adelaide conditions."
Chris Larson - "Even within a small area of Argentina the size & spikes on lorentziana are varied. One that I collected at the type locality of T. peiranoi was small enough to mistake for T. zecheri. Even in culture it is around 6 to 8” in spike."

Ray Clark .. "This plant is labeled as lorentziana blue. I’m unsure whether the blue us in reference to the foliage maybe, either way it’s striking and quite hardy."
Bob Hudson .. "T. lorentziana is normally white flowers the Blue on your tag i think will refer to the Blue flowers."
Andrew Flower .. "or it could be a Tillandsia koehresiana ??"
Len Colgan .. "It definitely refers to the flowers.
I can recall visiting nurseries in the USA many years ago, where the only forms of T. lorentziana had white flowers. This is because virtually all of their plants originated from Argentina (or possibly Brazil), where I only ever saw white forms.
However, when on my first collecting expedition in Bolivia, all of the habitats where T. lorentziana was collected yielded blue/violet flowers, except for two locations down south. I was really surprised. Of course, there was still quite a variety amongst the blue/violet forms due to widely separated habitats. The form you have is one of the larger ones.
I also recall re-visiting Bird Rock Tropicals and giving Pam a bunch of seed of a blue/violet form. I do not know if she had success. However, the blue/violet flowered forms are now available in the USA due to subsequent trips around Bolivia by Americans.
Conversely, in Germany there is a lot of the blue/violet forms because of all of the collecting in Bolivia years ago."
Julie & Dave Batty .. "Ray, I also have what looks to be another larger form of lorentziana that had been puzzling me – mainly because the flowers are purple, and also because there is a clear white edge around the petals (similar to cochabambae). This is not evident on the blue flowered type, but they do both have a paler middle section to each petal. Mine didn’t have any label at all so it was good to see your photos and suspect ours both came from the same source."
Derek Butcher .. "Julie: If in doubt, read the following, especially the note by Walter."
George Nieuwenhoven .. "Nice plant and photos Ray. They seem to do well in Adelaide, I have attached two photos of my plant it flowered in 2010 and has done before, it originally came from Maureen Hicks and that would have been at least 25 years ago so it has been around for a while where Maureen got it from is anyones guess but may have been Derek Butcher."
Ray Clark .. "Yes, we all seem to have plants from the same origin, my notes say that mine came from UD and I’ve had it here for about 18 months. Looking at Julie’s plant, yours and mine yes they not only cope with Adelaide weather, they love it!"
Cameron Kettle .. "also grows well, albeit as an infrequent flowerer, in tropical FNQ. Very adaptable / forgiving till."

Note from Walter Till 15 Apl 1997
I know the problem with the blue petalled Tillandsia lorentziana. Confusion is even stronger when you take into consideration that T. cardenasii (incl. the dwarf form T. pseudocardenasii) is widespread in Central Bolivia and is closely related to T. lorentziana. As the blue petalled T. lorentziana tend to have simple inflorescences I would not exclude that they represent natural hybrids of the two aforementioned species.
However, extensive field studies are needed to interpret this alliance correctly.

The following was referred to in Mez 1935 under T. lorentziana but he clearly mixed plants especially when he treated T. rusbyi as a synonym.
No reference in S&D. After consultation decided to treat this as Vriesea aff. lubbersii
Tillandsia lorentziana Grisebach by L. Wittmack in Gartenflora XL 313, t. 1349, (1891)
Translated by Butcher
Sect. Platystachys. Leaves from a longish base narrowing to linear, acuminate, rolled inwards, bent over, shorter than the shaft, bran-like scales, scales,( hairy) densely prominent, greyish-white. Panicle drawn together, formed by several spikes, the individual spikes with 3-5 flowers, prominent, alternate, somewhat apart from each other, rather equally long. Floral bract of a single flower (shiny scarlet red), imbricate, distichous, smooth, folded, longish, acuminate, nerved striped, a little exceeding the sepal, 3-4 times longer than the internodes. Sepals 1˝ times longer than the claw of the petal, acuminate, petals with threadlike claw and spatulate-lanceolate (white) blade, that is half as long as the claw. anther prominent, style even further extended, stigma blunt, ciliate.
Compared with T. balbisiana Schult, it is distinguished at first glance by the scales on the leaves and the lower bracts, and spreading from T. pruinosa Sw.
Stem 1 foot high. Leaves 4-7 inches long, base 8-10 lines wide, gradually narrowing, about the middle becoming narrow, gradually merging into the scape bracts on the stem, sheath-like, about 1˝ in long, spike 3-2 in. long, floral bract 1 in. Sepals 10/12 inch, petals 1 8/12 inch long.
Cordoba. At dry rocks in the valley of the river Auroyo near Las Penas. Lorentz n. 803)
Preceding this is Grisebach’s almost verbatim translation of the description in his “Plantae Lorentziae”, treatise of the Gottinger Society of the Sciences, XIX, 1874, p 271 (refer. Baker, Handbook Brom. 182).
" "The plant first flowered with Mr. Jacob Makoy in Luttich 1880, and in the year 1890 in the Orchid - Garden of the Garden-Inspector J C F Bouche in Endenich near Bonn, who directly introduced the plant. Our illustration is produced from an illustration of the original plant painted by Mr. Inspector Bouche, that he had determined and sent over to us. We have not seen the plant itself, only one leaf and an individual flower. Mr. J G Baker in Kew, to whom we sent the illustration, however also thinks that it is probably T. lorentziana. Hopefully we will later see another with a richly branched panicle: in the Grisebach collection there is such a plant and also has a single spike with more flowers. Mr. Inspector Bouche wrote the following to us about the plant:
Two years ago, I travelled through Paraguay with a friend, Mr. Schantzer, where different Bromeliaceae and orchids often repeatedly, grow, a Bromeliaceae species attracted my attention particularly through its odd habit, and which I had not yet noticed in known Bromeliaceae collections. Immediately near falls in relatively low growth we found an unusual prominent plant, strong bulblike appearance below, above the roots there is a tuft of leaves. The same becomes formed at the trunk by wide leaf bases, which provide the plant with a large natural reservoir. We are privileged to have imported examples of it here with one purely epiphytic form.
After about a year in cultivation with the plant in fibrous orchid-mix and swamp-moss, (I have cultivated similar plants of this type with good success for years), the same developed an about 35cm high flower stem from the centre, the lower part with green scape bracts, and in the upper part a shiny cinnabar red colour.
They have the same colour as the flower stem and its additional branches with surrounding bracts. The not large flowers are pure white and stands in effective contrast with the scarlet bracts so that the plant at flowering time is one much admired ornament of my Bromeliad collection. The illustration added to the text here was prepared from a watercolour drawing from my garden, shows however, as is abundantly clear with pictorial representations of flowers, that unfortunately are not those shining natural colour tones of the plant.
Through artificial fertilization of the flowers I succeeded in getting viable seed from T. lorentziana, that were sowed about two weeks ago. I hope that I will receive a large number of young plants soon. It multiplies very easily also through side offsets (babies), which this Bromeliad produces to 3-4 cuttings, and accordingly I already have 8 young plants, that each sells at 20 Mks per piece.
