Chris Larson 11/18 ... "The Guatemalan trade uses the name T. argentea for T. fuchsii f. gracilis. T. argentea is rare and difficult to grow except possibly in Cairns. Love to know if it is OK in brisbane???"
|Rob Bower 11/18
||Chris Larson 06/19 with banding
Rob Bower ... "Attached is a pic of my fuchsii f. gracillis from a few months ago. My 'argentea'? has shorter thicker leaves and solid leaf bases -no pic sorry. It very slow growing. They all grow fine on the Sunshine Coast."
Chris Larson ... "T. fuchsii has stouter leaves as well. T. argenteas leaves feel similar to T. atroviridipetala."
Chris Larson 06/19 ... "Zebras. I get a little cynical about the possibilities of these things. It started off ages ago with the single plant. Then it flowered and
. The pups went the same way.
This banded fuchsii v. gracilis was just one that I noticed amongst our stuff we imported. We often see these aberrations & often they dont carry through to the next generation. This shows the next generation ARE consistent, which is a good sign, but I want to see the second to see if it is stable and not cultural."
Steve Molnar ... "Another stunner that should be in all collections."
Sue & Steve Davidson ... "I purchased several of these from Bunnings and they are identical to the photo here. I also purchased one of these in SA and it has a green stem instead of the red. Flowers come out the same in both. Do I have two different varieties or just the one."
Chris Larson ... "All species have a natural variation. I would consider the colour of the scape not enough to doubt it is that species, especialy, as you say, everything else is the same. Often these types of things are not important to the taxonomist.
Things like stem colour, or any other substantial variant, are often used to give the plant a cv name. Though I do not know of one in this case. My collection is full of little notes on the labels with things like this written on them in this case it would be T. fuchsii var gracilis w/ green scape.
Any variation should be observed over multiple generations, well at least 2 - to see if it holds, if you intend to register it with the BCR. (Too many see the difference occur in one generation then assume that it will occur again.)
I just have them floating around with these little notes on the tags."
Lloyd Goodman ... "Chris is right on this one I had a conversation with David Benzing on this. When plants are grown from seed each has its own unique DNA. We only see visual differences but there is also different ways each plant can react to heat cold dryness etc. This is why one plant might thrive while another dies."

From Walter Till in J. Brom. Soc. (42: 99-102. 1992)
One of the most beautiful, small tillandsias, much desired by growers, is generally known as Tillandsia argentea. The plants have a bulbous habit because of the succulent leaf bases. The leaves are slender, more or less cylindrical, and tapering to a fine, sharp point (subulate). They are densely covered with a grey, frostlike bloom. The lax, simple inflorescences are coral-colored and bear 5-10 flowers with radially symmetrical violet corollas. They are found on the western side of the Sierra Madre in Mexico and southward as far as Guatemala.
If one reads the different descriptions, red and violet can be found as the color of the petals, but nobody investigated this discrepancy. In addition, the other characters derive from two different taxa and, as a result, all descriptions are a mixture.
Grisebach founded his Tillandsia argentea on fruiting material from southeastern Cuba collected by C. Wright in 1859. The type specimen is deposited in the herbarium of the University of Gottingen, Germany. An additional specimen is kept in the herbarium of the Museum of Natural History in Vienna, Austria, and probably also represents a type. Both specimens strongly resemble the habit of the plants collected in Mexico and Guatemala but they do not form bulbs since their leaf sheaths are not succulent. Plants of this kind are found only in Cuba and Jamaica.
In the last few years, living material has been imported by various Austrian and Czechoslovakian collectors from Cuba when that country increased its efforts to attract tourists. The vegetative plants attracted my attention and when they flowered in the greenhouse of the University of Vienna garden it was clear that they were different from the Mexican and Guatemalan plants. A comparison with the type specimen from Gottingen revealed that the living samples were completely identical with Wright's collection of nearly 130 years earlier.
As there are no synonyms under Tillandsia argentea, the mainland plants had to be described as new. I named them in honor of Franz Fuchs, the chief gardener of the Botanical Garden at Linz, Austria, for his merits in cultivating tillandsias and other bromeliads.
Since the plant in question is well known by most growers, it is not necessary to give an extensive description here, but it is introduced by the accompanying illustrations.
Typical plants (fig. 1) are found in the southeast of the state of Oaxaca, Mexico, between the cities of Oaxaca and Tehuantepec at an elevation of about 1300 meters above sea level. They represent the coarse-leafed form. Plants from the Mexican states of Michocan and Guerrero obviously belong also to the typical form.
In the state of Chiapas in southern Mexico and in Guatemala, Tillandsia fuchsii tends to have thinner and more slender leaves. I have described it as forma gracilis.
More striking and interesting is a population from the western part of the state of Jalisco, Mexico, which I have named in honor of the collector, Stefan Schatzl, senior gardener of the Botanical Garden at Linz, as Tillandsia fuchsii variety stephani (fig. 3). It differs from the typical variety by its wine-red to maroon inflorescences, the longer internodes of the rachis, the acute floral bracts and sepals, and the violet stigmas. That variety settles at the northwestern end of the distribution of T. fuchsii.
It should be noted that Tillandsia fuchsii is endangered since it is over-collected for commercial purposes. Thousands of plants are ruined each year in florist shops where they are stuck on pieces of wood or stone. They are completely unadaptable to the average apartment climate. Trade in this species should be limited exclusively to material grown from seed by horticulturists.
Key to varieties of T. fuchsii
1. Inflorescence red => 2
1. Inflorescence greenish brown => var stephanii
2. Leafblades angled and succulent at base => var fuchsii
2. Leafblades narrow filiform => forma gracilis
