Tillandsia graomogolensis
Species, was T. kurt-horstii.
Fragrant and fairly rare.
Ken Woods 01/09.
Bruce Dunstan 11/13.
Chris Larson ... "Hi Bruce. Your graomogolensis from me, is an ex-Isley form. It should be scented.
The silvery foliage on this plant is very nice & forms a nice clump quite quickly. (This used to be mis-labelled T. kurt-horstii & still is in some areas)."
Derek Butcher ... "I also imported this as T. kurt-horstii in 1991, so this name could be on labels. It was not until 1999 that Walter Till decided it was really T. graomogolensis which had been considered by Lyman Smith as a T. streptocarpa. Grao Mogol is a national park in Minas Gerais, Brazil."

Roots few, brown.
Stem simple or many joined together, not at all branched, up to 4cm high, 2 – 3mm thick, covered by the leaves
Leaves triangular, thick, above concave channelled, underneath convex, gradually narrowing towards the tip, tip filiform, at the base a large short sheath enclosing the stem, attached in 5 – 6 spirals, pale green, spreading in all directions, both sides with scales brown in middle and white at edges, on the upper surface these are blunt or on the narrow extended ligules above they are appressed, on the under surface all are covered with white hairs that spread backwards, 5 – 20cm long, 2 – 5mm wide in middle.
Scape brown, by no means flexuous, up to 20 cm long, glabrous.
Scape bracts decreasing from base to top, clasping the stem, lower ones similar to the leaves, upper ones unlike the leaves, longer than the internodes, acute but not prolonged acuminate, appressed, with shorter blade, lepidote like the leaves.
Inflorescence spicate, few flowered (5 – 6 Flowers) simple, densely distichous.
Floral bracts elliptic, lanceolate, acute, on the back lepidote on longitudinal veins, equal in length to the petal claw, brown/violet, 11 – 5 cm long
Flowers violet, 1.5 – 2cm long
Sepals elliptic-lanceolate, acute, glabrous, violet-brown, equalling the petal claw, up to 2mm connate then free.
Petals 2cm long, from the linear claw at the height of the sepal the blade widens to a circle and spreads out at 90º, of a lovely violet, claw white, all are glabrous.
Stamens 3 free, half as long as the petal claw, filaments flat, glabrous, 5mm long, Anthers linear, 2mm long, yellow, pollen grains oval, acute, yellow, Style short, white, shorter than the ovary, Stigmas never reaching the anthers, white
Ovary triangular, glabrous, white.
Type locality on rocks named ‘Pedra Rica’ near Grao Mogol, Minas Gerais, leg Alvaro da Silveira Jul 1926 #800 in Silveira Herbarium
Differs from T. retrorsa chiefly in the simple inflorescence.

Vaginae distincte limitatae amplexicaules, usque ad 1,5 cm altae, 1,7 cm latae, pallide brunnescentes supra glabrae nitentes, subtus in dimidio superiore dense albo-lepidotae. Laminae iuventute erectae, senectute plus minusve rectangulariter patentes, usque ad 15 cm longae, 4 mm latae, longe attenuatae, valde canaliculatae, utrimque dense albo-divaricato-lepidotae; lepides valde asymmetricae aliformiter elongatae. Inflorescentiae erectae vel paulum arcuatae, usque ad 20 cm longae semper simplices. Scapus inflorescentiae tenuis, 15-20 cm longus, glaber. Bracteae scapi erectae, basales subfoliatae, dense albo-lepidotae, superiores elaminatae oblongo-lanceolatae, atroviolaceae, glabrescentes. Spica complanata, 3-6 flora, usque ad 3 cm longa, 1 cm lata; rhachis a latere applanata, visibilis, modice flexuosa, glabra.

Tillandsia streptocarpa BAKER (Typus Balansa 615) similis, sed ab ea differt habitu dense pulvinato, caulibus tenuibus ramosissimis et copiose radicantibus, foliis angustissimis profunde canaliculatis congesto-patentibus lepidotis, inflorescentibus semper simplicibus, spicis brevissimis usque ad 3 cm longis, 0,5 cm latis laxe paucifloris.
