Tillandsia tricolor
"tricolor as complanata" (from Derek Butcher)
"tricolor as xiphostachys" (from Derek Butcher)
tricolor as grown by Derek Butcher 09/12

It has been suggested on the Tillandsia discussion group,
that the branched picture on this page would be better described as Tillandsia botteri

Tillandsia tricolor var. picta
For a while f. picta was synonymous with tricolor var. tricolor
It is now returned to a valid taxon as T. tricolor var. picta

Information from S&D p938-41
Includes description from T. acroleuca (treated by Lyman Smith as a synonym) in brackets

Plant stemless, often propagating by scaly branching rhizomes.(flowering to 30cm high, medium size)
Leaves many in a dense rosette, about equaling or shorter than the inflorescence, the outer ones arched-recurving, densely and minutely appressed-lepidote throughout;( forming a dense vase not in anyway bulbose rosette)
Sheaths elliptic-oblong, large; (brown.)
Blades linear-triangular, long-attenuate, 1 cm wide at the base, glaucous-green. (gradually narrowing to the acute but not pungent tip, to 30cm long and to 10mm wide in the middle, rigid, from sub-erect to curving and spreading, near anthesis the inside wine-red later with narrow and obscurely wine margins the remainder below light green above glaucous green, the back lightly and nearly punctulate lepidote)
Scape erect, slender; (short, strong, strictly erect.)
Scape-bracts erect, involute, densely imbricate, the lower foliaceous, the upper elliptic, acuminate, red. (sheaths densely covering the scape and if not, by the older blades with an acute tip from the lower part, red, involute.)
Inflorescence simple and distichous-flowered or laxly subdigitate from a few spikes; (few flowered, bipinnate panicle, almost equalling the leaves.)
Primary bracts like the upper scape-bracts, scarcely larger than the floral bracts; (much shorter than the spikes, with no blade, all are the same size as the sheaths of the scape bracts)

Key to the Varieties of Tillandsia tricolor

1. Leaf-sheaths uniformly deep castaneous.
2. Plant flowering over 25 cm high; floral bracts and flowers correspondingly large. => var tricolor.
2. Plant flowering not more than 25 cm high. => var melanocrater. Now treated as species in own right
1. Leaf-sheaths more or less pale maculate; plants 15-35 cm high. => var picta.

In publishing Morren's Tillandsia melanopus Mez noted two elements without naming either and designated as typical the first which consisted of only one collection, Pfaff 254. An examination of this specimen in the herbarium at Liege shows that it is not separable from T. punctulata. Consequently there is no choice but to reduce typical T. melanopus to synonymy and choose a name for Mez's second element which is a valid species. The number selected as a type under the new species is one of those originally cited by Mez.

Tillandsia ‘Tricolor’ from Guatemala nurseries
Notes from Renate Ehlers , Germany 7/2008.

The plant called tricolor is not a hybrid but occurs in hot areas in Guatemala by the thousands. In the nursery from Uwe Feldhoff hundreds of them were for sale with the name T. tricolor. It might be something like T. compressa !
Notes from Chris Larson of Gardenworld, Aust, importers 7/2008.
Both Andrew Flower from New Zealand and I have imported different T. fasciculata from Guatemala as T. fasciculata 'Tricolor'. When purchasing from Bromelifolia under that name you got a form of fasciculata (or close) which is Andrew Flower’s AB32 (fasciculata var. venosispica) - and he told me that this is where he got the plant he has photographed as var. venosispica on his website http://anwyl.com
The term "Tricolor" was used for the form of fasciculata, as the only ‘real’ T. tricolor in the Guatemalan nurseries is called 'Melanocrater' which can include, occasionally, one type of fasciculata!.
Note added 8/2013
Detail from Chris Larson; it also seems that plants called T. fasciculata ‘Tricolor’ can also refer to plants with strong affinities to T. rodrigueziana.

ST. PATRICK'S DAY by Derek Butcher, S.A.in Bromeletter 31(3): 10. 1993
Yes, I must tell you about March 17 because that is when I operated on a plant that Marie Robinscn here in Adelaide had obtained fran.Maurie Kellett. On the label was a comment that this plant had came up in a batch of seed of Tillandsia tricolor but which Maurie felt was a form of T.balbisiana. So it was prophetic that I was looking at an odd plant in the possession of the Irish on St Patrick's day. Regrettably the plant was not wholly green:
Marie kept telling me that the stamens were NOT exserted whereas I believed they should be. Eventually Maurie allowed me to take home the plant (on loan only). The plant is still intact except for one leaf & one flower spike. There were 5 spikes so it didn't radically change the look of the plant. However, there are now 4 spikes and this number leads you to T. tricolor, using my Tillandsia key! That is if the stamens were exserted! Let us remenber here that T. tricolor can have single or multiple spikes.
I believe that Maurie's guess is incorrect because his plant differs from balbisiana in.
1) Not a bulbose rosette
2) Inflorescence not dense
3) Has a red flower stem
4) Has keeled flower bracts.
5) Only the posterior sepals are-keeled and joined.

His plant differs from T. tricolor in:
1) Only posterior sepals are keeled
2) Posterior sepals joined for only l/2 length.
So at the moment I believe the plant is a T. tricolor even though I haven't seen the stamens exsert.
I am aware that Harry Luther has been moving names from inserted stamens section to exserted stamens section as with T. rhomboidea, but in this case I think it is the plant that is "doing the Irish".
If any of you out there has another of Maurie's ? T. balbisiana please tell me if the stamens are exserted. A drawing has been included to help you with your decision.

Butcher’s dissection
Plant stemless, rosette leaves numerous, 40cm diam, 40cm high when flowering
Leaf sheath distinct, 2.5cm wide, 4cm high, dull brown inside, outside green, nerved top portion then brown then white.
Leaf blade 30cm long, 1.5cm wide near sheath, narrow triangular, tapering to a point, strongly channelled, top 5cm terete, light grey scaled appressed on both sides.
Scape 15cm long, 0.5cm diam, red, internodes 2cm apart,
Scape bracts leaf like with red base covering scape, becoming more red with shorter green blade with scape becoming visible, finally last 2 bracts totally red with blade only 1.5cm long,
Inflorescence polystichous, lax, 20cm high, 10cm wide, compound with 5 spikes, rhachis visible, internodes 1cm apart, red with grey scales
Primary bracts similar to upper scape bracts but blade now down to 0.5cm long,
Spike side spikes to 10cm long, 6-7 flowered, top spike to 14cm long, 1.5cm wide, complanate, distichous, rhachis not visible, bottom 2-3 bracts sterile,
Floral bracts glabrous with a few scattered scales at tip, keeled, green with a pinkish overlay, exceeding sepals
Sepals 2.2cm long, 0.5cm wide, glabrous, green with a pink tip, posterior pair keeled and connate,
Petals forming a tube, 2.6cm long, violet blue with white slightly flared tip,
Stamens and Style included,

Thoughts in 2007
If Maurie had got his seed as T. balbisiana I could have understood why this plant also has the looks of T. xsmalliana!!

Tillandsia tricolor ‘Ocosingo’ EM82223 Notes by R Ehlers
Plant including inflorescence 20cm high
Leaves numerous, Sheath 2.5cm wide, 4cm long, Blade 15cm long, 5mm wide tapering to a long filiform tip
scape ca 12cm long
Scape bracts lower ones sheath encloses the scape, sheath 0.8-1cm wide, 1cm long, the tip linear, tapering to a tip, 7-8cm long, upper ones somewhat short sheath, the blade acuminate, nerved, weakly scaled towards the tip,
Inflorescence simple as long as the leaves
Spike 6cm long, 1.5cm wide
Floral bracts longer than sepals (exceeding by 3-4mm) 2.1cm long, 1.3cm wide, nerved, smooth, glabrous, however the tip weakly scaled and keeled,
Sepals 1.9cm long, 0.4cm wide, smooth, posterior pair sharply keeled and connate for 1cm,
Petals exceed sepals by 1cm, forming a tube, violet blue - bottom white, 3cm long,
Stamens ca 1mm longer than the petals,

In Dec. 1986 I wrote to Werner Rauh
EM 82223 collected in 1982 near Ocosingo Chiapas belongs to T. tricolor/ punctulata
It differs from T. tricolor by sheath to 2.5cm not 1cm
Spikes 1.5cm wide not 1.8–2.5cm
Internodes 4times as long as the bracts (not 6 times)
Floral bracts 2.1cm long , 1.3cm wide not 3cm x 1.8cm
Petals 3cm long ( not 7cm in S&D) not obtuse but acute
Stamens included or post floral as long as the petals.

I never got an answer. Lotte at this time also thought it might be something different.
