---From Ken, re- current 'Alec' discussion...
"The 'photo of Alec. Derek refers to is not my plant, I took the 'photos at the Illawarra Conference many
years ago, the plant came up for auction & was purchased by Richard Cornale who is a Member of our Group.
He may remember who donated it & its origin. These clues may jog the memories of other Nutters who were also at that Conference."
Mark Supple, Labelled "Orange variety".
Chris Larson, "Corsa". Unregistered variety imported '07 from Corsa S.A. (P/L) in Guatemala.
Chris Larson, "Percal". Unregistered cultivar from Costa Rica. "Pam Koides best".
Mark Supple 12/09. Originally purchased as unregistered variety tricolor (which is in Australia) but unfortunately not.
Peter Tristram 12/10, "Chacalapa" Mexico.
Chris Butler 06/11. Purple type ex.Bruce Dunstan.
Bob Hudson 12/12, "Percal". Unregistered, Costa Rica.
Chris Larson 11/10* var. densispica ?
Johm Olsen 12/12. var clavispica
*Chris Larson... "This is another of Len Summers’ plants. As I understand it they came from one of our Guate import competitors as T. fasciculata var densispica. The apparent bicolor flower is just due to the flower dying at the tip – was just blue. This plant has got ‘around’. Is it densispica?
*Peter Tristram 07/15, var. clavispica Trinidad*
Ray Clark 11/17, var. clavispica Trinidad*
George Nieuwenhoven 03/18 as 'Honduras' ??
Chris Larson 01/19 "Club Spike"
*Peter Tristram ... "This one is labelled 'Trinidad' by Lydia. The original plant nearly died in quarantine but the pups are doing well. I wonder if this ‘variety’ will get elevated to species in the current reviews. There is plenty of variation in the Cuban forms of var. clavispica as well, though the plants and their spikes all have a similar habit. Maybe there’s some utriculata or similar in their past?!
George Nieuwenhoven ... "This T. fasciculata came to me via Adam Bodzioch as T. fasciculate Honduras, it’s not in flower yet but I thought it was worth uploading a photo anyway, not sure what name it actually comes under but I am happy for any input. From memory I think that Len Colgan and I both imported this fasciculata from Germany some years ago. Len’s is a bit different to mine."
Chris Larson ... "Another I have had for quite some time – ex-Guatemala. Parted with quite a few as T. fasciculata 'Club Spike'. In flower today – not registered."

Key to the Varieties of Tillandsia fasciculata in S&D
1.Spikes rarely less than 1dm long; floral bracts 35mm long or longer --> 2
1.Spikes, or at least their fertile portions, rarely over 1dm long; floral bracts scarcely more than 25mm long --> 5
2. Floral bracts even or at most faintly nerved toward apex --> 3
2. Floral bracts prominently nerved, beaked, drying dark = var venosispica
3. Spikes strongly complanate --> 4
3. Spikes but slightly complanate = var convexispica NOW fasciculata
4. Spikes erect = var fasciculata
4. Spikes nodding, secund = var pendulispica
5. Spikes clavate with long slender bracteate sterile bases = var clavispica
5. Spikes short-stipitate or subsessile --> 6
6. Inflorescence ample --> 7
6. Inflorescence few-branched or simple --> 8
7. Floral bracts coriaceous, glabrous = var densispica
7a. Floral bracts greenish white, petals white = forma alba
7. Floral bracts thin-coriaceous, somewhat lepidote = var floridana (NOW HYBRID)
8. Spikes lax = var laxispica
8. Spikes dense; floral bracts strongly incurved or cucullate --> 9
9. Primary bracts ovate, the lower ones caudate or acuminate; spikes linear-lanceolate = var uncispica
9. Primary bracts suborbicular, apiculate; spikes ovate = var rotundata (NOW SPECIES)

Ross Little 23/12/13 Chris: This is the plant I mentioned to you today I have tagged as T. 'Percal'. Thoughts ???

Chris Larson 23/12/13 Hi Ross. That is what I have as Percal. Mine had more branching, but it is the same thing. If in doubt post it here & ask Pam.

Ross Little 23/12/13 Chris: I'm fine with it, Bruce D. wasn't quite sure was all and I couldn't find a photo on the BCR or on the DVD to confirm its ID.

Derek Butcher 24/12/13 I confirm that a photo of 'Percal' is on the DVD. It is said to come from Costa Rica. Perhaps we should make a New Year's resolution to register as many of these nurseryman's names of T. fasciculata as we can. I was hoping that Brian Sidoti would give us an insight into this species the same as Juan Pinzon did for the T. utriculata for his Doctorate but alas.
The advantage with registering is that detail is captured rather than hearsay. We have details on Beauty, Hondurensis, Jim Hyde, Naundorff, Pat Coutts, Tropiflora and Unispica. So it is reasonable that we try to solve the Percal bit.

Derek Butcher 27/12/13 I have worked up something for a Tillandsia Fasciculata Group.. see attached. I have some 27 in this group but extras to look at are this 'Percal' and perhaps 'Chacalapa', 'Corsa' (there is already an ionantha with this name so this has to be straightened out) and 'Magnifica'. Please let me know any information you may know regarding these names.

Bruce Dunstan 29/12/13 Derek: Could we add T. rangelensis to the list of related spp.?

Derek Butcher 30/12/13 Bruce: First I must ask why this species? It was not mentioned in Sidoti's paper and when it was described in 2009 it was compared with T. moscosoi.
I don't have a photo of it alive!

Tillandsia fasciculata Group
Ever since Lyman Smith published Flora Neotropica Part II in 1977 we have seen Nurserymen giving names to special forms of T. fasciculata which had been found in the wild. There are also plants from private collections that have not been formally identified as well as hybrids within the complex. Some have been registered, some not. It is difficult to link these names with some of the new species described since 1977, because botanists rarely refer to cultivar names or nurseryman’s names in their notes. Therefore it is possible that these cultivar names are part of the following species. We leave you to decide!
Tillandsia fasciculata complex according to Brian Sidoti and Kenneth Cameron at Monocots Conference 2013.
acostae, beutelspacheri, compressa, copalaensis, fasciculate, fasciculata v. clavispica, fasciculata v densispica, fasciculata v. densispica forma alba, fasciculata v. venosispica, flavobracteata, grossispicata, gunther-nolleri?, hubertiana, inopinata, kuzmae, jalisco-monticola, magnispica, marabascoensis, polita, rhomboidea, rodrigueziana, rothii, rotundata trelawniensis, welzii , zoquensis.

Derek Butcher 18/08/17 .....remember that Adolpho only described T. inopinata in 2008 and he did warn :
For a long time the Mexican specimens of the genus Tillandsia L. with digitate-compound inflorescences were identified with the name of T. fasciculata Sw. However, extensive work of gathering in diverse parts of the country has allowed us to determine that, under this epithet, they grouped several different species in fact, among those that we can mention are T. maritima Matuda (1971), T. hubertiana Matuda (1975A), T. flavobracteata Matuda (1975B), T. jaliscomonticola Matuda (1975B) and T. rothii Rauh (1976), as well as T. marabascoensis Ehlers & Lautner (Ehlers, 1992), T. zoquensis Ehlers (2002) and T. macvaughii Espejo & López-Ferrari (2005), recently described. The inadequate application of the name T. fasciculata has surely been due to many of the characters in herbarium material being lost that allow us to distinguish the taxa appropriately with live plants, such as the number, the size, the colour and the form of the spikes, the consistency and texture of the floral bracts, the form of the rosette and the habitat. Mez, himself (1896) mentions that T. fasciculata was a polymorphic species and described seven varieties of the same one, using material from Mexico, the Antilles, Central and South America, and Florida in the United States. It is for the same reason that Smith and Downs (1977) in their Flora Neotropica recognized 10 varieties of T. fasciculata, two of them later moved to specific status by Gardner (1984).
The type specimen of Tillandsia fasciculata Sw. (O. Swartz s. n., BM!, S(x2)!), comes from Jamaica and it corresponds to plants of small size (Chart 1) with plump spikes, ellipsoid and more or less short pedunculate (Fig. 5c). In Mexico, the populations that have these characteristics are found only in the Yucatan peninsula (see Appendix) and the material coming from other parts of the country correspond to different entities, some of which have not been described to date. This is the case of the two taxa proposed here as T. grossispicata and T. inopinata:"
