Tillandsia baileyi
Ken Woods 12/05.
Ian Hook 08/08.
George Niewenhoven 12/14
Geoff Beech 02/19 as 'schidieana v. Major'. (probably T. baileyi)
Justin Lee 02/19 T. baileyi
Geoff Beech ... "?? labelled as 'schidieana v. Major' (sic)"
Dale Dixon ... "I think it’s Tillandsia baileyi ‘Haley’s Comet’"
Geoff Beech ... "Thanks Dale and Graham looks right for 'Halley’s Comet' the label threw me for a minute."
Rob Bower ... "Or just baileyi ?"
Justin Lee ... "My T. baileyi seems to clump up before flowering."
Bob Hudson ... "Word has it that 'Halley's Comet' is a sport of baileyi ?"
Rob Bower 02/19, 'Halley's Comet'
Chris Larson 02/19, 'Halley's Comet'
Chris Larson ... "I’m with Rob. T. baileyi. Unless it has viviparous pups from the spike at a later stage, it would then be T.Halley’s Comet."
Dale Dixon ... "I have both forms of T. baileyi and I believe that they are correctly identified. What I’ve noticed with my plants is that the viviparous form produces offsets at the base prolifically even if not flowering, while the non-viviparous form doesn’t. It still produces pups but not in the quantities that Halley’s Comet does. Have you noticed this also? Do you think this could be a spotting character to aid in identification? Interested in your observations."
Chris Larson ... "Hi Dale. Yes at times. But I find that Halley’s Comet does not TEND to have strong pseudo-bulbs like this plant has. Also, seedling T. baileyi's have a tendency to throw up multiple pups before flowering. This occurs across many species.
But to answer your question more directly; yes this does give some idea, but not enough to hang your hat on."
Chris Larson ... "Just noticed this clump of Halley’s Comet in flower. The plants are always thinner. The floral bracts don’t overlap tightly like the normal T. baileyi. It is not distichous either. Check the scape bracts and primary bracts in this photo – then have a look at Geoff’s photo."

Ian Hook 12/23 T. baileyi?

What I had always assumed was T. baileyi has just flowered with bi-coloured petals !!

Ian Hook 11/23 baileyi ?? bi-coloured petals !
Ian Hook 11/23 baileyi ??
Ian Hook 11/23 compared with Halley's Comet
Bob Hudson has suggested T. Moonlight, but my plant has only 1/4 white petal tops (Moonlight has 3/4 white and all white filaments). Also my leaves look more baileyi like.
Pam Butler suggested chapalilliensis or 'Tooshi'. Most pics of chapalilliensis imply a yellow colour in top of petals and growth habit still not quite right. But then again.... chapalilliensis seems tangled with T. 'Scurfy' which has a more similar leaf/growth. This leads to the tangled web of schiedeana crosses, including 'Tooshi', which is a possibility.
Graham Besgrove suggested a close similarity with a plant he has of schiedeana x ionantha. I have not seen a photo, but ionantha seems strange.
Eric Gouda "Looks much like T. flavoviolacea which is less bulbous than T. beileyi and selfing and coming through from seed."

In my investigations I am leaning towards T. Taurus, another from the tangle of schiedeana hybrids. Particularly since many of my Tills have links to Ken Woods and Terry Davis. (and apparently the name 'Taurus' was suggested by me in 2012!)

Tillandsia baileyi - Texas' Endangered Species by SUE GARDNER in J. Brom. Soc. 25(6): 207-8. 1975
Of the three tillandsias found in Texas, Tillandsia baileyi is the most limited in range. It is found growing only in an isolated area of South Texas, approximately 20 miles south of Kingsville. Its entire habitat covers approximately fifty square miles. All of this area is ranch land; much of it is part of the gigantic and world-famous King Ranch. The land is sandy rangeland with scattered clumps of live oaks. It is in these live oak clumps that T. baileyi makes its home, in the company of the much more wide spread T. recurvata or "ball moss". To the uninitiated, the much larger clumps of T. baileyi when not in flower may easily be mistaken for giant clumps of "ball moss".
Some of the very large clusters of T. baileyi may exceed 18" in diameter. In the spring months, small brilliant pink spikes bearing blue petaled flowers distinguish it even to the untrained eye.
U.S. Highway 77 cuts a path through the King Ranch in this area, and numerous road-side parks and rest stops take advantage of the cooling shade of the oak clusters. Some of these rest stops boast historical markers recalling armies who are said to have rested in the shade of these same oaks on their way to fight for the independence of Texas from Mexico. As recently as 1971, when most of these photographs were made, the branches of the oaks in these road-side parks were heavily laden with colonies of this bromeliad, but with the increased popularity of bromeliads in South Texas, collectors have next to eliminated this lively wild flower from the road-side parks. They have been aided by the highway department who keep the lower branches of the trees removed, often destroying thousands of these plants at a time. These practices along with the very limited range of the species put its survival in the wild into the hands of a few ranch owners. This set of circumstances concerned some of the members of the Corpus Christi Bromeliad Society, who recommended that this plant be placed on the Texas Conservation List. Several months ago at a meeting of TOES (Texas Organization for Endangered Species) T. baileyi was added to the list and is now illegal to collect from public lands. Attempts have been made to introduce this native tillandsia into wild-life refuges in South Texas, but lack of knowledge about its limiting factors, makes these attempts less than certain, and only time will tell how much success will be experienced.
