Tillandsia edithae
Species, Bolivia.
(Len Colgan highlighted that T. edithae was wrongly described considering ICBN rules. It should actually be T. edithiae (with "iae"). But the Taxon List currently calls it T. edithae.)

Peter Tristram ... "Blooming edithaes inspired me to get the camera out and do some portrait shots.
The Germans have collected so many forms of T. edithae some of which I have been lucky enough to obtain. Many are very slow growers though, compared to the vigorous clone most of us have. The form from Renate E is huge, for edithae and one pic shows it alongside a large plant of the usual form, another with a form which is quite small and compact, though differing considerably from the ‘forma minor’ forms from Lotte, now var. auraucariifolia I assume.
The group pic shows some of the imports from Germany with the giant RE plant in bloom as a guide."
Peter Tristram 01/13. From 2010 trip to Germany. Dark emerald green leaves, slightly different from the other ‘green’ forms I have imported a few years ago. I have noticed that they all prefer some shade and are quite slow growing. Maybe the green forms grow on shady cliffs. var. araucariifolia?
Peter Tristram 01/13. Large form, Los Negros.
Peter Tristram 01/17. Very small form.
Ray Clark 12/17. Var. araucariifolia ?
Peter Tristram 01/17 ... "This interesting edithae, a compact, small form mentioned in the first post, came in without a tag or the tag moved during Q. I first thought it might be T. nana but the bloom shows differently."
Chris Larson ... "I think even more important than using "T." instead of "Tillandsia", is this issue of calling it T. edithae or T. edithiae – I do this too – my tags all have T. edithiae. Ever since Len Colgan highlighted that T. edithae was wrongly described considering ICBN rules, I have been spelling it T. edithiae (with "iae"). I note that the Taxon List currently calls it T. edithae.
If it was described without applying the rules properly, is T. edithae still correct? Or is T. edithiae (with iae ending) still correct?"
Peter Tristram ... "Good point, Chris. From memory Harry Luther proposed the change to edithiae but it was left as edithae because it was less hassle given the length of time that the incorrect Latinisation had been used. I know I changed labels but reverted to the old spelling some time ago now. I am sure Derek will add to the discussion! As to your last question, I have no idea."
Ray Clark 12/17 ... "I believe this plant to be edithae var. araucariifolia, a quick search of the DVD reveals the first conundrum, spelling of the sub species, is it araucariofolia or auracariifolia? My reason for believing I have a var on the species is the very short leaves"
Derek Butcher 12/17 ... "Could well be, oh observant one! Detail on the species for those who don't have the DVD and are curious is attached.
One of the Araucaria is called the Monkey Puzzle tree which may be why the Journal of the BSI had it spelt wrongly.
Peter Tristram was growing a form called unofficially 'Minor' which may well be the same."
Peter Tristram 12/17 ... "As far as I can see, the var minor edithae I obtained from various sources - Lotte, Holm, Heidelberg and others in Europe, is the var. araucariifolia, (spelling copied from taxon). I wonder if Eric agrees as he will be familiar with the many forms. As for the spelling it’s a pain to remember! Var. minor is easier! I guess your one is also ex Europe, Ray. It’s such a slow grower too.
I do find the colour of the inflorescence of this form has quite an orange influence in the red, like the green form also has."

NOTE ; The type locality given in the protologue is wrong and has been confused by A. Blass (who had brought the plant to W. Rauh's attention) with the data given for K/285 in Krahn's list of field numbers. W. Krahn actually collected this plant in 1964 under his number K/295 in the Dept. Sta. Cruz, Prov. Florida, 338km along the street from Cochabamba to Sta. Cruz, Quebrada Chaupiuno, 2500 m.
DISTRIBUTION. Known only from the type collection.

Die in dichtem Rasen an steilen Felswanden wachsende Pflanze besitzt verlangerte, bis 35 cm lange (wahrscheinlich noch langer werdende), hangende, an den wachsenden Spitzen aber bogig aufsteigende Stammchen, die in dicht spiraliger Anordnung kurzdreieckige, zugespitzte, 5-6 cm lange, oberhalb der nicht deutlich abgesetzten Scheide 2-2,5 cm breite, etwas sukkulente, beiderseits groB, fast pruinos grau beschuppte Blatter tragen (Abb. 7, links). Der kurze, 3-5 cm lange und etwa 5 mm dicke, kahle, runde, grune Infloreszenzschaft wird von spiralig angeordneten, subfoliaten, dicht grau beschuppten Hochblattern umhullt, von denen die obersten bisweilen dicht gedrangt stehen und eine Art Involucrum um die kopfige, einfache, etwa 4 cm lange und 2 cm breite, 8-12-blutige Infloreszenz bilden (Abb. 7, rechts). Die floralen Brakteen sind langer als die Sepalen; die basalen tragen eine kurze Spreite, die apikalen sind spreitenlos; sie sind etwa 2 cm lang, bis 1,9 cm breit, ecarinat, cucculat, an der Basis grunlich, gegen die Spitze zu rotlich und dicht grau beschuppt ; von den weiBen, hautigen, bis zum Grunde freien, 1,4 cm langen und 5 mm breiten Sepalen sind die hinteren carinat, das vordere ecarinat. Die 3 cm langen und 4 mm breiten Petalen sind an der Spitze abgerundet und leicht spreizend; in der oberen Halfte sind sie leuchtend zinnoberrot, gegen die Basis zu weiBlich; die bis 2,5 cm langen Staubblatter und der bis 2 cm lange Griffel sind in der Blute eingeschlossen (Abb. 7, rechts).
Der Fundort dieser zur Bliitezeit sehr attraktiven Tillandsie sind steile Felswande in einer Hohenlage von 2700 m bei Sorota, Prov. Lare¬caja, Dptm. La Paz in Bolivien. Die Pflanze wird in der Sammlung von A. Blass unter der Nummer K 295 kultiviert.
T. edithae gehort in den Verwandtschaftskreis der in Sudperu in Trockentalern verbreiteten und an ahnlichen Standorten wachsenden T. caloce¬phala Wittm. Sie unterscheidet sich von dieser aber durch die einfachen und nicht zusammengesetzten Infloreszenzen sowie die leuchtend zinnoberroten Bluten, die bei T. calocephala von blaB- bis dunkelvioletter Farbe sind. Auch sind die Blatter jener weniger sukkulent und weniger pruinos beschuppt. T. edithae ist bisher nur vom Typstandort bekannt.

Peter Tristram ... "Nice, Bruce. A beautiful form of T. edithae from Lotte Hromadnik, originally as edithae var minor. Good to see it thriving in Brisbane!"

Tillandsia edithae var. araucariifolia Gouda var. nov. (fig. 3,4). J. Brom. Soc 64(2):76-79. 2014. as edithiae var. araucariofolia.
A variety that differs from the type variety in having strict (erect), relatively short, 3-4 cm long leaves ending in a sub-pungent apex (vs. curving leaves 5.5-8 cm long with a more or less flexible apex).
Type: Bolivia, new road from St. Cruz to Cochabamba, 1500 m. elevation, C.S. Gouda s.n. October 1996. Introduced into the Utrecht Botanical Gardens in 2008, flowering June 2014. (holotype L).
Plant long caulescent, 14 cm tall, very dense, with many leaves.
Leaves polystichous, coriaceous, 3-4 cm long, very densely lepidote, on both sides, with subappressed whitish and dark centered scales, cinereous-green;
sheaths large (about half the length of the leaf), with a layer of extending trichomes at the margins, thin coriaceous, indistinguishable from the blades, pale green and membranaceous toward the base;
blades acute and sub-pungent, divergent (sub-erect), somewhat stiffly and more fleshy toward the apex, triangular.
Peduncle short and concealed by the leaves, wholly covered by bracts, erect, 3 cm long, 7 mm in diameter;
peduncle-bracts erect, foliaceous.
Inflorescence simple, fertile part ovoid and acute 3 cm long, 1.5 cm wide, densely 7-flowered.
Floral-bracts ample, inflated, 2.2 cm long, 2 cm wide, many times as long as the internodes, much exceeding the sepals, glabrous except the lepidote apex in the lower ones, bright red, rounded but slightly cucullate or apiculate, erect, very densely imbricate, thin coriaceous, nearly even, ecarinate, sub-orbiculate with thin margins.
Flowers contiguous, subsessile;
pedicel 2 x 5.5 mm long, strongly complanate and bicarinate.
Sepals membranaceous or chartaceous, 11-13 mm long, 4.5-5.5 mm wide, with broad hyaline margins, evenly short connate for 1.5 mm, glabrous, few nerved, elliptic, rounded or slightly cucullate obtuse, pale (whitish) green, adaxial ones distinct from the anterior ones, carinate and strongly incurved.
Petals fleshy, 23-25 mm long, 3.5 mm wide, ligulate, rounded, bright red.
Stamens included; filaments strap shaped and flaccid, straight (not plicate), 1.8 cm long;
Anthers dorsifixed at about one fourth of its length from the base, linear-sagittate, obtuse, 3 mm long, pale yellow.
Pistil slightly exceeded by or about equaling the stamens;
ovary complanate ovoid, 5 mm long, tapering into the style;
style slender, elongate and many times as long as the ovary.

Etymology: the plant resembles a short branch of Araucaria araucana (Monkey-puzzle tree) . Araucario (like Araucaria) - folia (leaves).

Although this variety is very beautiful, it is not easy growing like the typical variety.
It grows very slowly: only doubling in size during the last 6 years and flowering for the first time now. Only one of the original 3 shoots has flowered and now it is going to produce small pups at the base.
In 1974, Werner Rauh described the stunning Tillandsia edithiae Rauh (1974: 19), with its bright red inflorescence and fleshy red corolla, from La Paz, Bolivia. The species is quite variable and plants from several populations look different. The most common form has somewhat purplish tinged cinereous leaves and in 1995 we saw steep mountain slopes fully covered with this plant in the province of Santa Cruz, Bolivia, indicating that it is locally very abundant. Near Samaipata we collected a very short leaved and succulent form that unfortunately did not survive. Some populations have somewhat larger plants with leaves about 8 cm long (Fig. 1) and others look similar but with shorter leaves of about 5.5 cm long. In cultivation they can grow to over half a meter in length, developing many offshoots on the old leafless stem. Although beautiful, they do not flower often. In a clump of the several shoots, normally only a few will flower at the same time and some of my clumps have never flowered.
There are also more green forms that do not develop that purplish leaf coloration, even when hanging at the same location (see Fig. 2 also from Samaipata). In fact each population looks slightly different and it would not be practical to give all those forms a name except for the very obviously different ones, like the variety described in this article.

Subject: Tillandsia barborkae
Eric, Walter & Harry
Ever since this was published I have thought it to be a synonym of T. edithiae
The protologue says inflorescence compound but the drawing shows simple. I did ask Halda for a photo but got no reply.
Needless to say unofficial names for T. edithiae, like green form, orange flowered, etc are around
Any thoughts as to treating this as a synonym?

From: Harry Luther. To: Derek Butcher
Its the same as T. edithiae, will be treated as such in the next binomial list.
