Tillandsia chapeuensis
Peter Tristram 10/12. Bird Rock Tropicals.
Peter Tristram 10/12. Heidelberg BG.
Peter Tristram ... "The red flowered Brazilians are hard to beat! These are the 2 forms of chapeuensis, from Bird Rock Tropicals and Heidelberg BG, that I posted before but photographed in isolation. There are interesting differences such as flower shape, branching and foliage shape but I suppose this species has a wide habitat so variation is to be expected."
Peter Tristram 05/14 large form.
Peter Tristram ... "At last I have bloomed the so-called ‘large’ form of T. chapeuensis, this baby from Germany. It is occasionally available in the US too and I have another clone ex Bob H (muchas gracias!) and one from RFI. I just wish 2 clones would bloom for seed, though there are a few other rather lovely species in bloom to cross it with at the moment. It is pretty big too, at least twice the width of a good gardneri, strangely this one being the smallest of my specimens. T. chapeuensis seems to be a fairly variable species complex centred in Bahia (Morro de Chapeu), all that I have seen being highly ornamental."

Bruce Dunstan ... "These are so different in habit compared to T. chapeuensis. Peter Tristram’s images in flower show them beautifully."
Peter Tristram ... "T. chapeuensis has open flowers and is damned hard to set much seed on, like gardneri v. rupicola."
*Peter Tristram ... "There's talk of this mostly red flowering group being revised yet again. Souza would call your form gardneri v. rupicola, as per his posts on Facebook. He's forgotten about Cabo Frio as the type locality for that species and doesn't like to be reminded to check the type and the description. For now, call it chapeuensis! The chap with the long spike that's in Oz could also have a new name, as per Die B - longiscapa I think. I haven't bloomed one for years so can't check against the description."

Tillandsia chapeuensis W. Rauh, sp. nova, Trop Subtrop Pflanz. 58: 24-29. (1986)
Tillandsia gardneri Lindley, in Brasilia late distributae affinis, sed differt ab illa foliis angustioribus solidioribusque (quae sunt in Tillandsia gardneri mollissima) et scapo inflorescentiae rigido erectoque et inflorescentia laxe elongata neque cephalo-ellipsoida.

Holotypus: Rauh 56 545 (Aug. 1981), HEID
Habitat et distributio: terricola in rupibus arenaceis prope cataractam Morro do Chapeu, Brasilia, una cum forma permagna Tillandsiae strictae Sol. et Tillandsiae horstii Rauh itemque cum speciebus terricolis generis Hohenbergia et Velloziaceae.

Plant forming clumps, growing on sandstone, single plant flowering to 25cm high.
Leaves numerous, making a broad to erect rosette,
Sheath not distinct, white, ca. 1.5cm long, 1.5 cm wide, lepidote.
Blade narrow triangular, to 20 cm long, 1.5 cm wide next to sheath, channelled, gradually narrowing to a thin, erect or the upper half with a reflexed tip, both sides very densely white scaled, for that reason the leaf seems snowy white, the scales eccentric, the leaf edges with longer wing like scales.
Scape erect, 0.5 cm thick, densely enclosed by leaf like scape bracts.
Scape bracts with pink sheath and longer filiform blade.
Rhachis edged, 3mm thick, lepidote.
Inflorescence erect, laxly bipinnate to sub digitate, with ca. 8 diverging to erect spikes.
Primary bract ovate acuminate, to 2 cm long, pink, thin, topside almost naked, underneath dense scaled, shorter than the spike.
Spike narrow lineal, complanate, to 4 cm long, 1cm wide, short ( 0.7cm) stemmed, 4 to 6 flowered, with 1to2 sterile bracts at base.
Flower sub sessile, to 2.3 cm long.
Floral Bract beginning as dense imbricate, later lax so that the green lepidote rhachis is visible, keeled at tip, long – lanceolate – acuminate, 1.8 cm long, pink, dense sparrig lepidote, exceeding the sepal.
Sepal 1.5 cm long, posterior ones carinate, the tip pink and naked, green towards the bottom and scattered lepidote, almost free.
Petal lively carmine red, ca. 2cm long, ligulate, the tip weakly reflexed and shallowly notched, the bottom white.
Stamens and Style much enclosed.
Filament ribbon like, not plicate, with yellow anther.
Stigma lobes shorter than the anthers.
Type locality near waterfalls, Morro do Chapeu, Brazil

Differs from T. gardneri in-
1. Leaves narrower and more robust.
2. Scape erect and rigid.
3. Inflorescence laxly elongate not capitate elliptic

T. chapeuensis is a very decorative plant, whose leaves are pure white because of the dense scales, moreover they are not soft and laxly hanging, like T. gardneri ( fig. 15, right; fig. 17,) but usually stiffly erect and weakly succulent.
The inflorescence is not capitate, (fig. 15; fig. 16, right), but elongate (fig. 15, left; fig. 16, left). T. chapeuensis is known only from the type locality up to now.
Because of the terrestrial growing and the branched inflorescence T. chapeuensis is similar to T. gardneri Lindl. var. rupicola Pereira but is distinguished by the long stem, the secund leaf formation and the white flowers. Moreover, the var rupicola only comes from the island Farol at Cabo Frio (state Rio de Janeiro) see ( Fig. by E. Pereira, photo III, in: “Species novas in Brasilia Bromeliacearum XVIII, Bradea, VOL. III, 27, 1981.)
