Chris Larson .... "Another of those plants which we imported as T. fasciculata ‘Triclor’.
Many friends have this one as it came in some years ago & as many of you know, I’d rather these cheaper species get spread around the nutters before offering them to the general public where most will never be seen again. In the past I named them aff T. rodregueziana as I had never seen the flower & it was a rough guess – and I made this clear to those that wanted to take a punt. This doesn’t have the twist in the branches associated with rodregueziana, but nice all the same.
This plant has thick leathery green leaves & looked good before flowering. The pot is an 8” pot. The plant has not been highly fed which is why I’ve had to trim the base leaves.
Due to the lack of provenance it can’t be treated as a different species – and so it just goes into that mass of plants which show the morph between one ‘species’ & another."

Peter Tristram ... "I am not sure the aff is even necessary though as it has that rodrigueziana look about it, certainly more so than a couple I have in bloom (pics attached). One is from Lydia as rodrigueziana and the other from Walter as an unk, possibly dugesii. It is obviously not dugesii and both are probably in the rodrigueziana fold though even more aff. than your one. As you say, it’s a morphing mix. It’s a great species for the lumpers sporting a dazzling range of shapes, sizes and colours! Love them all!"
Tony Tucker ... "The tag says melanocrater, the eyeball ponders christagalli, seems too large for tricolor.
Is this within the range for rodriguezii? spike extends 60 cm beyond leaves. Waiting on a bloom but thankful for any id suggestions in the meantime."
Peter Tristram ... "Hi Tony, consider a form of the variable T. rodrigueziana."
Dale Dixon ... "These two Tillandsias have had their ID queried on an international Tillandsia page. First one was bought as T. botterii and the second one as T. rodrigueziana."
Peter Tristram ... "T. botteri. Plants were imported long back as tricolor but with multibranched spikes, ex Alfredo Lau, ex Vera Cruz area, in my case. We, at a TPE decided that these would be closer to botteri. Check the DVD. The Yanks sell a different plant with that name, not botteri either IMO. Harry Luther agreed re our decision on botteri.
The rodrigueziana could be one of mine, ex Selby, which I thought could be a large paraisoensis at one stage. (If not, then it’s very similar!) That was before I had any verifiable paraisoensis. Renate actually had exactly the same plant in her car when I got a lift to a DBG conference (2006) and it was decided to be best left as rodrigueziana. I believe provenance played a part too. rodrigueziana is like fasciculata - so variable and likely a bunch of species lumped. Harry simply referred to the groups as hybrid swarms. I’m sure Pam knows more about the Mexican stuff than any of us!"
