Peter Tristram 10/13...."These two lovely red-flowering Brazilian specimens are not the typical forms of the species, T. chapeuensis and T. sucrei. Both came from the Heidelberg collection. The sucrei is a monster compared to the ‘normal’ forms we have here and I have seen all over the world. Details from the HBG datatbase are below.
T. sucrei: Provenance: Brasilien, Est. Rio de Janeiro, Serra dos Órgănos (Orgelgebirge), nahe Rio de Janeiro,, 1400 - 1600 m
Collector: Reinhold Thieken. Source: Reinhold Thieken (Triberg), 30.03.1973"

Peter Tristram 10/14...."Many of you will have bloomed the little red Brazilians over the winter months and the last to bloom for me is always the delightful T. sucrei. For such a small plant it has a monster inflorescence! This year is a real treat as all of my forms are in bloom, so lots of pollinating to get true sucrei seed too (and a few hybrids). The smaller form in the photo with the 2 plants is the one sucrei collectors all have, which was imported at least 30 years ago. The larger one I obtained from Goettingen Botanical Garden in Germany and is blooming for the first time. It is even larger than the other large form I have, also from a German BG, that I posted last year, and also in bloom. The flowers on the Goettingen plant are much paler than all of the other forms too and I have heard there is an alba form as well, though I’d have to go to Germany to have any hope of being at the right place at the right time to get a piece.
T. sucrei seems easy to grow on the east coast so I wonder how southern and western growers go with it? It’s natural habitat is smack bang in the middle of Rio, so very different to where something like T. yuncharaensis originates.

Tillandsia sucrei E. Pereira, Rodriguesia 26(38): 115, pl. 4. 1971.
Desc from Ehlers in Die Bromelie Sonderheft 3 p29-30, 1996
Plant. Growing on rocks, single or in groups, almost stemless to short caulescent, with branching roots and a short brown rhizome at the base, 5-12cm high, flowering 8-15cm high, forming a dense, secund rosette, 3-6cm in diameter.
Leaves: Many, 15-45, 4-8cm long, almost soft and thin, silvery with dense appressed scales, appearing whitish grey velvet.
Sheaths 6-10 mm wide, indistinct, dense appressed lepidote towards a glabrous base.
Blade 3-5cm long, 4-7mm wide at base, triangular acute or attenuate, involute, both sides densely covered with round, large, spreading scales.
Scape: 2-3cm long, shorter than the rosette, erect, covered by 3-4 imbricate subfoliate pink scape bracts.

Type. P. I. Braga & D. Sucre 1715 (holotype RB, isotype HB), on steep rock faces, Morro do Pavao, Copacabana, Rio de Janeiro, Guanabara, Brazil, 19 Oct 1967. 50- 500 m.

Named after the Brazilian Botanist D. Sucre.

Comments: This small Tillandsia was for a long time a precious rarity, which grows endemic on steep rockfaces in the State of Rio de Janeiro and for that reason needs protection. The rockface however is almost vertical and therefore inaccessible. Therefore the species has a big chance to survive. There is a great variety in size to be observed, in one location is growing a type double in size as the normal one, named var. major.
Culture presents no real difficulty if one considers that the temperature rarely drops below 15° C.

TYPE. P. I. Braga & D. Sucre 1715 (holotype RB, isotype HB), on steep rock faces, Morro do Pavao, Copacabana, Rio de Janeiro, Guanabara, Brazil, 19 Oct 1967.
DISTRIBUTION. Known from the type collection only.

It has similarities with T. brachyphylla and T. geminiflora but differs in the shape of the leaves, bracts and sepals.

It is dedicated to my colleague Dimitri Benjamin Sucre, Rubiaceae specialist at the Botanic Garden.
