Tillandsia mallemontii
Ken Woods 02/08.
Peter Tristram 12/10. (Bruce's)
Herbarium specimen, Paris.
Ian Hook, 10/05. (! probably T. Nezley !)
Ian Hook, 01/07. (! probably T. Nezley !)
Chris Larson to Derek Butcher, 30/01/16 ... "Brent was observant yesterday and spotted this one which is what I always thought as T. Nezley (the one I referred to the other day) – though the photo of the flower on the BCR shows it is not Nezley.
Some may find this one “around” as it gets mixed in with T. mallemontii in the polypak stuff in Bunnings etc.
Any ideas ?"
Derek Butcher ... "According to the description in S&D this species is quite variable and your photo could well be of T. mallemontii. Botanically speaking, Baker in 1889 got it horribly confused with T. linearis.
Now to 'Nezley'. I got my plant in 1984 from a forgotten source in Qld. Its photo is on the BCR. The parents quoted were usneoides and mallemontii. I assumed it was a hybrid and did not check to see if it was in fact a hybrid. I accepted the name as Nezley even though it was probably ex Nezley because people rarely call a plant after themselves. The name 'Nezley' first got into my checklist in 1991. The plant was discussed at Albury in 2006 and nobody could supply any history. It was suggested that the parentage could well be T. usneoides x T. recurvata.
[Ed. See historical findings under 'Nezley' and 'Nes Misso']
And so the name Nezley stays in the records.
As an aside in 1991 I got a couple of seedlings from Maurice Kellett called T. mallemontii but when they flowered they looked like small T. streptocarpa so I affectionately called them 'Mauries mallemontii' but did nothing further."
Ian Hook ... "I have some pics of mine on our web under T.mallemontii titled "probably Nezley".
I originally got from 2 sources (but don't know which survived), 2005 BSA Show and an old collector, Bert Plemback 2007
Shape, flower, and growing habit different to mallemontii and to usneoides. It doesn't flower much for me and has an insipid pale blue non-fragrant flower on short stem.
Chris Larson suggested the non-flowering bunch he saw here was T. Nezley.
Maybe Nezley stretches all the way from almost usneoides to almost mallemontii (or single flowered streptocarpa)."
Derek Butcher ... "The whole problem with 'Nezley' is that we cannot find its real origin. Who did the hybrid? Everything is so secretive.
We know that T. mallemontii can be up to 20 cm long. I enclose a herbarium specimen from Paris. Sorry I do not have the Berlin one.
The plant I got in 1984 called Nezley has blue flowers which when you come to think of it is strange when one of the alleged parents has green flowers. Therefore, if there is such a thing as 'Nezley' I would have expected greyish petals and feel we should put a couple of your photos in the BCR to show variation in petal colour to be expected. We will see what Geoff thinks.
After all of this I think we should not be too hasty in writing off the name T. mallemontii which seems very variable in size.
Note that with all the new hybrids we are going to have increased problems of identity. It may be safer to call a plant Tillandsia hybrid than guessing what it might be. The only mention in the BCR regarding a usneoides and mallemontii is our 'Nezley' and we don't even know if that is correct.
BTW, I think VB Bob should be looking at 'Holm's Mallensis' for his almost 'Nezley'"

Plant caulescent; roots present; stem very slender, 1-2 dm long, branching.
Leaves distichous, to 12 cm long, cinereous, densely pruinose-lepidote;
Sheaths narrowly ovate, to 2 cm long, membranaceous, glabrous within and below on the outside;
Blades mostly spreading or reflexed, irregularly curved, linear, long-attenuate, 1-1.5 mm in diameter.
Scape terminal, straight to strongly curved, to 13 cm long, lepidote, almost filiform;
Scape-bracts like the floral bracts but sometimes long-laminate, l or 2 immediately below the inflorescence or rarely one somewhat remote.
