Bruce Dunstan 08/19 "small Orange"
Chris Larson ... "Just took another photo of this one yesterday and I was thinking….. most of us, I think, associate T. bulbosa ex-Belize with a larger than normal plant. These imported many years ago from Jeronimo as from Belize are far from the largest I’ve seen."
Bruce Dunstan ... "Flowering for the first time a plant from Barry Genn. Certainly an orange but it has grown into a large plant."
Barry Genn ... "Bruce, I should have known that you would have grown it twice the size that I do. The thing is I have a larger orange form so I tagged that one small form."

Tillandsia bulbosa Hybrid?? "Dark & Hairy"??
Rob Bower 08/20 Unknown.
Pam Butler 08/20 bulbosa hybrid and pseudobaileyi
Rob Bower ... "I tried my luck with this group previously for ID of the attached. Any suggestions?
If you zoom in you can see the body of the plant is quite scurfy."
Bob Hudson ... "I have been growing this one for years as T.butzii Sliver. I think Chris Larson has mentioned it may be T. butzii Hyb."
Chris Larson ... "This is one that Barry Genn & I were talking about in Feb, after the Till Day. Love some input into its origins. Anyone remember?"
Rob Bower ... "I've had a few bids (thanks) – mainly for a form of butzii or a hybrid of. Its so scurfy I cant see it as a form of butzii but that may be just that I haven’t seen enough butzii forms. I wondered if it might be a butzii x caput-medusae just from the look but BCR doesn’t have that cross – which I found hard to believe.
I don’t remember where I got it but it was a couple of decades ago."
Chris Larson ... "I think I remember it as T. caput-medusae X something back years ago - but someone must have a better memory than me. It is around in collections - so it needs a name.
It also had a name something about furry, from memory."
Nanette Collingwood ... "I think I have a version of it called ‘Dark & Hairy’ or similar. And I could be wrong, but I also think mine came from Margaret & Bill Paterson."
Pam Butler ... "My thoughts on this plant. - This is one of my plants on the left, it was purchased from Len Summers. Another I purchased from Barry Genn as bulbosa hybrid.
The plant on the right is T. pseudobaileyi.
I see a lot of similarities between the two plants and they are both in flower now. The inflorescense is very similar."
Rob Bower ... "I think the plant on the left is the same as mine – one step closer…"
Chris Larson ... "I remember getting this plant many years ago, possibly in the 80s or early 90s - and I'm pretty sure Len had T. bulbosa 'Dark & Hairy' on it. (I was close with Furry).
It is the same as the one that Barry & I have.
I'm thinking probably back to either Keith Golinski or Roly Reilly. Does Peter Tristram know?"
Peter Tristram ... "Looks like a lot of pseudobaileyi involved to me."
Peter Tristram* 09/20 forma alba
Vic Przetocki** 03/23 "mini green"
Peter Tristram* ... "I took this pic before I left so am missing the flowers. They are quite white with a purplish tinge, from memory. The plant was described as bulbosa forma alba by Hiro with an article in the BSI Journal. I have been chastised for giving it the cultivar name, 'Hiro', though Hiro himself and his co-discoverer, Chester, like that idea! Is there a formal reason that a described plant cannot receive a cultivar name? I know Derek Butcher believes this and probably Geoff Lawn too but I would like to know what others know and finalise this discussion! The plant was introduced into the US by Skotak and is sold by Tropiflora and others now."
Derek Butcher ... "Great plant but confusion about the name which is T. bulbosa forma alba. A plant named under the ICN rules always has precedence over a cultivar name making 'Hiro' redundant."
Vic Przetocki** ... "I have had this plant for a long time now (as "miniature green") but have never noticed so much colour in the foliage when it comes into flower (assuming the flowering cycle has started). Leaves don't look damaged at the base and the hydroponic fertilizer I use has not affected my other bulbosas. While doing the photos I unintentionally dislodged the tiny pup which is also showing the leaf discoloration. I will keep monitoring the clump in the next 2-3 months to see how it develops."

Overall, the floral characteristics of this new form lie within the normal size range of the type of Tillandsia bulbosa. But when in bloom, this new form has an unmistakable bright yellow inflorescence and pure white flower. It is a rare occurrence among plants of the type.

Habitat: The plant grows epiphytically in bright, open forest. In the same area, Tillandsia anceps Lodd. , T. leiboldiana Schltdl, and T. complanata Benth. were observed as epiphytes.

Plant acaulescent, 10-30 cm tall, very variable in size and color, often aggregated, the sheaths greatly inflated, forming a small, compact ovoid pseudobulb.
Leaves 8-15, the outer ones often reduced and sheath-like, 8-30 cm long, mostly exceeding the inflorescence;
sheaths ample, abruptly constricted into the blades, stiff-coriaceous, orbicular, greatly inflated, 1.5-3.5 cm wide, densely appressed-lepidote toward the apex, brownish to silvery green at the apex, often purple- or red-banded at the margins; blades often spreading or reflexed, mostly flexuous, fleshy coriaceous, involute-subulate, 10-25 cm long, 1-5 mm in diam., attenuate, pungent, minutely appressed-lepidote, pale to very dark lustrous-green.
Inflorescence simple or subdigitately compound of 2-5 polystichously arranged spikes, 7.5-23 cm long, subdense, orange-red or green;
scape erect, 5-15 cm long, densely covered by bracts;
scape-bracts densely involute-subulate, with foliaceous blades, exceeding the inflorescence, the upper ones often orange-red in part; axis short, but exposed between the spreading bracts, angled, lepidote, often pale-rose;
primary bracts as the upper scape bracts, but the upper ones more ovate and acuminate, clasping the spikes, the lower ones often exceeding the spikes with the foliaceous blades;
spikes short pedunculate (ca. 0.5 cm), suberect or spreading, lanceolate, complanate, 2.5-5 x 0.7-1 cm, acute, densely and distichously 3-6-flowered, often with one sterile bract at the base and apex;
rachis slightly exposed by the narrow bracts, nearly straight, sharply angled (dry), lepidote;
floral bracts erect, somewhat incurved at the apex, imbricate, subcoriaceous, ovate, 1.1-1.9 cm long, 2-4 times as long as the internodes, much exceeding the sepals, acute, (obscurely) carinate, densely lepidote.
Flowers tubular-erect, contiguous, sessile; receptacle obconic, ca. 1 mm long;
sepals thin and stiff, with veined surface (only when dry), oblong, 1-1.2 cm long, with broad veinless margins, obtuse and obscurely apiculate, posteriorly more or less connate (1/4) and bluntly angled at the base, glabrous;
petals linear, to 4 cm long, acute, blue-violet or rarely white; stamens much exceeding the petals, the longest (3) about equaling or shorter than the pistil,
filaments straight(?), flat, the exceeding part dilated and terete, anthers dorsifixed (at 1/3), 2.5 mm long; ovary ovoid, 4 mm long, tapering into the slender style.
Capsules slenderly cylindric, to 4 cm long, more than twice as long as the floral bracts, abruptly short-beaked.

Distribution: Mexico and the West Indies to Ecuador and N. Brazil Epiphytic, from near sea level to 1350 m alt. 83 collections studied (23-GU, 11-SU, 32-FG).

Culture and use: A very decorative small species; demanding moderate to high humidity, bright and sunny place; easily grown and propagated in a greenhouse.

Few persons, who have the opportunity of comparing this richly coloured plant with the figure about quoted, in the ‘Exotic Flora’, could at first sight perhaps consider them to represent the same species; yet, except that this is a better grown specimen, with a more perfect spike, and that the upper leaves and bracts are of a bright scarlet hue, tinged with yellow, I see no difference, and am bound to consider them the same. The original plant was transmitted from Trinidad, by the late Baron de Schack; our Garden is indebted for this splendid variety to the mission of Mr. Purdie, who sent healthy specimens from Jamaica, which on being simply suspended by a piece of wire, from the beam of a moist stove, flowered in the winter 0f 1846-7. In proof that the highly coloured leaves afford no permanency character, these became after flowering, of the same uniform green as the rest of the foliage.
The Tillandsias exhibit strange forms, and many of them highly beautiful inflorescence; but they are unintelligible, when studied in the Herbarium, and little sought after by those who send home living plants; so that our knowledge of the species is but imperfect. It is to be regretted, too, that they are difficult to keep long in a state of cultivation, generally dying soon after flowering, more frequently without blossoming at all.

Plants clustered, two or more united at the base, and sometimes growing in two opposite directions, and in the instance here represented, slightly attached to the branches of trees by slender feathery fibres.
Stem simple, leafy at the base, immediately swollen and bulbiform.
Leaves a span or more long, subulate, coriaceous, rigid, waved and somewhat spirally twisted, terete from the singularly incurved or almost convolute sides, dark green, naked, the bases of the lower ones singularly dilated into very broad membranaceous sheathing bases to the bulb, pale coloured with a red margin, dotted; the upper leaves gradually smaller and almost bracteiform, richly tinged with scarlet and yellow.
Spike racemose, the branches compressed, and clothed with distichous, scarlet, imbricated bracteas, entirely concealing the flower-buds.
Flowers protruded beyond the bracteas.
Calyx of three green convolute sepals.
Corolla of three linear-lanceolate, purple, acuminate petals, twice as long as the calyx.
Stamens and style exserted.
Filaments dilated below the apex.
Stigmas three, cuncate, fringed at the edge.
