Len Colgan 02/18 ... "Well done John, I have had plants of this Paraguayan desert species for a long time, but not one has ever flowered."
Bruce Dunstan 02/18 ... "Same for me Len. I have taken pieces off my clump and they flower for others but I’m still yet to flower it."
Peter Tristram 02/18 ... "I bloomed 2 plants last year, ex Bruce, ex me lol but apparently with altered chemistry! One of Bruce’s chemically enhanced plants had a branched spike. I’m sure I posted pics which I also sent to some of my European colleagues who’d always asked to see a blooming specimen. Walter disputed its identity until I let him know the specimen was well fertilised. He was happy with the single spiked plant though, both from the same mum. I tried to pollinate and cross it without success. So, Len, you might have to feed yours!"

Sepals oblanceolate, subfree, membranaceous, abaxially densely pale lepidote except for the scarious margins, adaxially glabrous, nerved when dry, broadly acute, the adaxial ones carinate, (20-)23-27 mm long, ca, 6 mm wide.( adaxially 2.5 mm connate, pale green, to 29 mm long)
Petals 40-50 mm long, the claw linear, ca, 3 mm wide, the blade obovate, 4-6 mm wide, with slightly undulate margin and rounded at the apex and revolute, violet (Ramella !).
Stamens about equaling the throat of the corolla, filaments flat, linear, anthers linear, ca. 8 x 0.5 mm, dorsi fixed near the base,
style much longer than the ovary,
stigma lobes erect, spreading. (Filaments subbasifixed, slightly plicated 1 cm above their bases, narrowed towards their apices, white with a touch of violet in the upper half.
Anthers greenish-yellow, pollen pale yellow. Gynoecium 44 mm long, ovary obovoidal, 4.5 x 2.2 mm, pale green, style 38 mm long, white, stigma white, the lobes erect, spreading, papillose. Ovules stout, short caudate.)

This remarkable new species unfortunately is known to the authors only from 19 herbarium plants with inflorescences mainly in post flowering state. Only the holotype and one isotype G, each exhibit one anthetic flower. Although its novelty is out of discussion, characters of fresh pollen and detailed stigma morphology are lacking as well as actual petal color and eventual fIower odor.
Phytogeographically it seems to link the Andean relatives from Tillandsia subgenus Anoplophytum with the east Paraguayan T. esseriana. It probably represents an isolated remnant population from pleistocene periods of cooler and drier climates.
Differs from T. esseriana in
1. Larger habit, up to 30cm
2. Leaf indument subtomentose.
3. Scape much longer
4. Floral bracts densely lepidote
5. Sepals densely lepidote
Tillandsia ramellae by Walter Till and Susanne Till in J. Brom Soc. 47(1): 30. 1997
Last year we described Tillandsia ramellae W Till & S. Till (TILL & TILL, 1995) as a novelty based on herbarium material which kindly had been brought to our attention by its collector, Lorenzo Ramella from the Conservatoire et Jardin botaniques in Geneve, Switzerland. The material was mainly fruiting and some floral details were lacking in the diagnosis.
Mr. Ramella also sent us a living specimen which flowered in the Botanical Garden of the University of Vienna in December 1995 (figs. 13, 14). This fresh flower material enables us to add a few characteristics to the original description:
Flowers ca. 3 mm, stoutly pedicellate, 50-54 mm long, not at all fragrant.
Floral bracts pale green to flesh-colored.
Sepals adaxially 2.5 mm connate, pale green, to 29 mm long.
Petals to 52 mm long.
Filaments subbasifixed, slightly plicated 1 cm above their bases, narrowed towards their apices, white with a touch of violet in the upper half.
Anthers greenish-yellow, pollen pale yellow.
Gynoecium 44 mm long, ovary obovoidal, 4.5 x 2.2 mm, pale green, style 38 mm long, white, stigma white, the lobes erect, spreading, papillose.
Ovules stout, short caudate.
Tillandsia ramellae usually grows on steep rocks (escarpments), only occasionally is it found as an epiphyte on trees. It is recognized by its yellowish green foliage which is densely covered by appressed trichomes giving the plant a dull, pale gray appearance (fig. 13). The inflorescence is usually simple and distichously flowered, rarely an additional spike is produced. Floral bracts are dull flesh-colored in the field but pale green in cultivation, petals are violet blue (fig. 14). The sepals, densely lepidote except for their margins, are very distinctive.
In the protologue this new Tillandsia has been compared with T. esseriana Rauh & L.B. Smith. However, according to the floral details and the stigma morphology it is related to the alliance of T. lorentziana Griseb. It is hitherto known only from one isolated mountain in northwestern Paraguay at the Bolivian border. It seems to be a locally endemic species and should be legally protected from exploitation.
