David Sheumack. Originaly as T. confertiflora.
Derek Butcher ... "Tillandsia ‘Silver Coin’ would have been named by Derek Butcher in March 2011 for a plant imported to Australia from BirdRock, Cal, USA in the 1990’s as either T. coinaensis or T. confertiflora.
The plant does not seem to correspond to either species having a large inflorescence that is hanging. This tendency to hang may be caused by growing the plant out of bright sunlight or a much lower altitude. Investigation as to identity continues. Apparently the BirdRock plant was identified as T. coinaensis by Harry Luther so leave as is.

FLOWER Sessile, erect, overhangs flower bract by 3mm, and with a few spreading petals, very inconspicuous, scentless.
PRIMARY BRACT Shorter than the spike, the bottom ones similar to the stem bracts, sheath oval, 1/2 to 1/3rd as long as the spike, and cupshaped at the bottom, firmly enclosed, the bottom blades acuminate and the outside rolled, those above short and hook tipped, naked, shiny green red, the tip with weak appressed scales
FLOWER BRACT As long as the sepals or 1mm shorter and firmly enclosed, 17-20 (22) mm long, 15-18mm wide, elliptic, tipped, hard leathery with 1mm thickened keel, the edges very thin becoming almost transparent, outside shiny plump-red-green, naked, the tip with small dense appressed trichomes, the tip nerved when dry, smooth side bare, inside light green, with dense brown small trichomes, strongly nerved and covered with a slimy liquid.

DIFFERS FROM T. rubro-violacea IN THAT
1.- Leaf sheaths twice as narrow.
2.- Shorter spreading spike.
3.- Leathery sepals equally short connate.
4.- Short tongue-like petals, spreading at tip.

On a trip through North-Peru, that I had 1976 together with three friends, I found in the area near Coina a Tillandsia unknown to me. We were visiting the German Dr. Oswaldo Kauffmann in Trujillo. He had told us of his small hospital in Coina where on spare ground in this area there was a black flowering orchid. My friends, who were Orchid fanciers, could not be held back any longer!. We had to be there, even if the way was bad, we wanted to look for this orchid. Over Otuzco we go towards Coina. We sought the black jewel there long and intensively, as we had originally intended. In Coina, they had run out of petrol, and we were consoled by the fact that the Petrol tanker was coming next day and it did eventually arrive 4 days later!. We did not find the fabulous orchid, (naturally!). This remote area was not quite useless because I found a very interesting Tillandsia there. That was 12 years ago, and since then I have observed it in my collection, compared it with the literature, waited for flowering, etc, etc. I introduce this beautiful plant under its new name to you today.
