Dale Dixon ... "Pretty sure this is the one that Eric Gouda says is Tillandsia confinis. I flowered it about a month ago and posted to the group. What are the label details on yours?"
Rob Bower ... "Not much on label except I got it from Chris Larson. My amateur guess it that the one you flowered was confinis and mine is confertiflora - from the other emails it was previously confinis v minor. That ties in with the fact yours was a larger longer flower spike. Lesley's recent confertiflora pic is pretty much the same as mine. Hers came from Peter Tristram."
Chris Larson ... "Jeff Kents plants often have collection data - this is a plant Bob Hudson, Peter Tristram and I imported from Jeff Kent. The habitat data show that T. confertiflora and T. confinis are separated by some distance. T. confinis coming from around Cuzco, where T. confertiflora comes from far north of Peru and into Ecuador. Does anyone have contact with Jeff to find out if he has detail? Peter?
Or has anyone checked this plant against the 2 descriptions?"
Peter Tristram ... "I have emailed Jeff Kent. See what we find out. Doug Binns sent me photos of what looks like this plant a few years ago. Remember, confertiflora used to be confinis v minor. Also the dvd will do your head in regarding this group. There are many descriptions!! Bolivia to Colombia is a wide habitat range."
Lesley Baylis _t ... "This is my T. confertiflora, flowering now, which I believe I acquired from Peter Tristram some years ago. I'm definitely a clumper...!! and slightly panicking as Ross Little wants an inflorescence so that he can do some butchering.
It's not looking its best as we've had a bucket load of rain and no sunshine for several weeks... but still I don't think I'll be letting it out of my sight.... for too long...!!"
Dale Dixon ... "Mine is exactly the same as Lesley’s. It’s a small plant. Orange bracts are confinis. Red bracts confertiflora."
Ross Little ... "With a little persuasion Lesley allowed me to remove one of her 14 precious inflorescences from her awesome clump of Tillandsia confertiflora to chop up and check its bits, photos attached.
Comparison check taken from the Butcher files: Till. confertiflora Andre and Till. confinis L.B.Smith
Till. confertiflora petals, 5 mm, blue violet .... yes, agrees.
Till. confinis petals 7 mm, white .... no.
Regarding bract colour: bract colour can vary with light, temperature and humidity.
Till. confertiflora scape bracts and primary bracts – bright red.
Till. confinis upper scape bracts with red sheaths.
I saw an orange bracted form in Ecuador in 2015, whether it was confertiflora or confinis ?? no petal colour to confirm.
For those better at checking the finer details than me, refer to the herbarium I have prepared today from Lesley’s plant, let me know if you require more details and photos."
Peter Tristram ... "Hi Ross, all: In my opinion don’t change the labels. On the way to Brisbane Ross and I went over the bits kindly donated by Lesley, at Pine Grove. Great job preparing the sheet, too, Ross - reminds me of the good old days. Seems a good match to confertiflora to me. Always check a plant against the type specimen and other herbaria material too, as in the DVD. Check the floral parts in particular first as, if they don't match, the rest is a waste of time. Species identification is more about the finer details than the overall look, which is a guess… I guess.
Jeff Kent last sent me this info:
"I collected it in west central Ecuador at 1200 msm. The same area as Tillandsia mima and Ae. mexicana but a bit higher in elevation. I need to look up the locality. The other form is from Eastern Peru at 1500+ msm in the Alto Mayo region and is more difficult to grow. It burns if fertilized too much."
I can't remember the 'other form'.
I await another email with locality. Jeffrey is a wonderful library of collection info. I think I need another couple of days in his greenhouses, especially after his more recent trips to Ecuador and Colombia!"
Eric Gouda ... "Hope not to make the confusion even larger, but I think this plant under discussion is T. confinis again.
I think T. confertiflora has short ovate spikes and those in T. confinis are more lanceolate, see the type photo above of the André plant. The protologue says that the leaves are densely lepidote, flowers white.
Also see florapix image above that is probably T. confertiflora, petals were not seen, but inflorescence looks much like it."
