Barry Genn..."It's a long slog growing seed. Nearly Twenty years before the reward of flowering them."
Bruce Dunstan...."As mentioned, what I thought may have been TV hitchcockiana has flowered and looks to be very close to yours. My plant was labelled V. cereicola so I guess I have no reason to change it." (See T. cereicola, this web site).
Andrew Flower..."Bruce, you are probably right.
Your plant's flower surely looks the same as mine (the inflorescence on yours is proportionally much higher than mine.)
My plant is labelled "TV Pending" for now!
One of our local growers disputed my name, saying it is TV cereicola, so I went looking further afield on the International Brom ID site:
Walter Till replied "Tillandsia (Vriesea) cf. cereicola" (meaning in effect there is not enough evidence available to make a decision, we need to compare it to TV. cereicola using more characters than you have supplied so far)
Eric Gouda thinks it is more like T. hitchcockiana but hitchcockiana and cereicola are probably the same species anyway. (well, that's what I understood from his reply)
So when I get another flower on mine, I'll be dissecting it and measuring/photographing the parts for submission to the experts - meanwhile I guess I leave it in the pending basket."
Peter Tristram..."As far as I can figure TV hitchcockiana was described before TV cereicola and they are variations on a theme! I have accumulated many clones of this group, either as hitchcockiana, cereicola, or NOIDs. I even collected one, and they are all basically impossible to differentiate florally, within a range of sizes, degrees of branching and pendulousness. One group pups with interesting stolons though, like giant espinosaes."
Derek Butcher..."When Mez described cereicola in 1906 (See attachments which show differences to what Smith showed us in S&D) and Smith described hitchcockiana in 1930 there were clear differences between the two species.
Both Mez and Smith agreed that if sepals widely exceed the floral bracts you have hitchcockiana and if less than you have cereicola. Mez also said that sepals were unequally joined for cereicola but Smith does not mention this.
These descriptions would have been correct when the plants were found but it seems plants found since, including these latest photos, show that when you compare sepal/floral bracts relative sizes you scratch your head. Nobody has yet checked if sepals are joined."
Bruce Dunstan ... "Something to get the taxonomists excited. I struggle to tell hitchcockiana and cericola apart. The floral bracts do appear to be shorter than the sepals on this plant, although it looks so close to Andrew's cericola images on the disc."
|Peter Tristram 11/13. The really large form I got from Kentís about 1980. It doesnít pup on stolons.
Peter Tristram ... "Nice hitchcockiana imho Ė floral bracts flare out as distinguished from cereicola. Check the DVD incuding my pics of a plant from Lotte which is from a paratype from memory or at least from the type locality.
cereicola pups on stolons too. I wonder which hitchcockiana clone as itís got lots of branches. Quite a few coming into bloom here from many sources Ė Europe, Knize, BRT and from the old days Ė Kent, Krauspe, Tropiflora.
Dale Dixon ... "Itís a bit difficult to get good images of this one. The petals are just a slightly darker shade than the spreading floral bracts.
Already the plant has two good size pups developing."

ECUADOR: Loja: between El Tambo and La Toma, alt. 1000-2200 m., 1923, A. S. Hitchcock 21323 (G, type; US, cotype).
This beautiful and striking species is related to T. incurva, T. cereicola and T. patula and the close resemblance of its inflorescence to that of T. subimbricata would argue that the latter species, though its flowers are as yet unknown, probably belongs to the section Platystachys also.
T. Hitchcockiana is easily distinguishable from its near relatives by the combination of densely furfuraceous-lepidote leaves and of floral bracts shorter than the sepals.
The recurved-spreading character of the floral bracts is of very doubtful importance as a specimen (Fendler 1524) of T. incana in the Gray Herbarium shows both incurved and recurved floral bracts on the same spike, yet its strongly spreading-tipped bracts are the most-striking single feature of T. Hitchcockiana.
The species is unusual in having two lateral folds on each petal, a rare occurrence in Tillandsia.
