D. tequendamae
DD. cylindrica

Derek Butcher 23/09/13 ... "To me you have a fine specimen of TV porphyrocraspeda (Vr. cylindrica). See attached key."
Peter Tristram 23/09/13 ... "Just for the record Steveís very attractive, smallish, erect-spiked plant was named by Harry as tequendamae who assured me not all populations are pendant."
Derek Butcher 24/09/13 ... "But look at the key by Gilmartin below. She does not mention whether the inflorescence was hanging or not and as far as I am aware Harry did not dispute her Monograph on Ecuador regarding these two species. I ask all of you to critically look at the shape of the primary bracts."

Key by Gilmartin...
8. Inflorescence compound
- 10. Primary bracts orbicular (D), apices rounded, or apiculate, at least the lower spikes obscured at antithesis........9. Vr. tequendamae
- 10. Primary bracts ovate to triangular (DD), apices acute-attenuate, spikes exposed in part throughout inflourescence.
- - 11. Leaves 40-70cm long, inflorescence erect at antithesis, usually 20cm long or more.........10. Vr. cylindrica
- - 11. Leaves to 35cm long or if longer, then petals with crenulated margins, inflorescence curving at antithesis, 8-18cm long or tripinnate and to 45cm long
(Ed. Note that Vr. cylindrica is now Tillandsia porphyrocraspeda.)

John Olsen 12/18
Bruce Dunstan 09/19
John Olsen ... "Not thriving in my environment but flowering."
Alfonso Trudu ... "The locality of Tequendama, presumably related to this plant, is at over 2500 m above sea level to the west of Bogota, in Colombia. Maybe the difference in elevation between Brisbane and Tequendama could be a contributing factor why your plant is only just flowering. However, I still believe it is a great success that you made the tequendamae flower. Let's hope for some pups."
Peter Tristram ... "The one in cultivation came from near Quito in Ecuador and is quite different to the tequendamae in Colombia. Itís a regular bloomer and tolerant of extremes. Most TV species grow above 2000 m so require more shade in summer to avoid heat stress. If you search tequendamae in the BCR youíll find one entry and Iíll be discussing this erect-spiked plant and more of these species in my talk. Soon thereíll be another rego under appenii too."
Bruce Dunstan ... "Peter Tristram's plant flowering. Some of the bracts are oval and then some further up the scape are more pointed. Joys of taxonomy. This plant seems to enjoy my conditions, thankfully we are yet to have the extreme spring heat."
Bruce Dunstan 11/20 ex MF ex Ecuador
Bruce Dunstan, in situ Santander
Bruce Dunstan ... "This plant was collected by Michael Ferenczi in Ecuador and does well in Brisbane considering the lack of elevation. Thankfully this Spring has been very mild with nothing over 30 degrees at Nundah.
It is under 50% shade with lots of air movement. In nature you only see them above 2000-2500m where the cooler influence protects them but they can often be in full sun at that elevation. Attached are some growing near Velez on the eastern range in Santander."
Peter Tristram 10/20
Peter Tristram ... "I had a couple in bloom when I got home in mid October.
In my experience Its best to give it shelter, especially from hot summer sun, though itís pretty hardy for an altitude plant. Itís an epiphyte too, so shade suits it. This form, imho, keys close to porphyrocraspeda as well and is quite different to the tequendamae seen in many parts of Colombia, always above 2300 m. The Colombian tequendamae are damned hard to grow in cultivation too, I gather."
Ray Clark 01/21 upright spike
Ray Clark ... "This plant flowered for me over a week ago now and I'm quite pleased as (TVs) such as this one do not traditionally do too well here in SA."
Peter Tristram ... "Good job! Either your microclimate work is brilliant or this baby is tough as! I think the former. Why it's labelled tequendamae, a usually pendant species described from near BogotŠ in Colombia, is another story that Iím sure you know!"
Chris Larson ... "I think Ray has done well with this in the hot dry Adelaide winds. However, this form is the hardiest for me. I have a shadecloth area facing east at home(Melbourne). This plant grows easily sitting out past the eaves, so it doesn't mind the cold, winter rains."
Ray Clark ... "I have avoided TVs such as this plant for a while now as I dispatched quite a few to the green bin before I got a handle on things. This plant, like brachycaulos and many other thin leaved Tills, spends winter in my wife's Cacti house. There's no heating, just plenty of airflow and protection from the excessive wind and rain. Summer is a completely different affair for me and that's where paying attention to micro-climate as Peter has implied seems to have payed off. Listening to Chris I might re-appraise my thinking this coming winter, but maybe not too much"

Tillandsia tequendamae Andre, 1888 (Enumeration Bromel.) p. 8; Andre, 1889, pp. 103-104, pl. 36.
PLANT ca. 50 cm tall, from erect rosette;
LEAVES 40-60 cm long, outer¨most leaves shorter, to 7.5 cm long, blades 4.5-7.0 cm wide, narrowly triangular, densely gray-lepidote throughout, apex attenuate to filiform,
sheath 7.0-15.0 cm long by 6.0-8.5 cm wide, dark reddish brown, conspicuous:
SCAPE ca. 5-6 mm in diameter, exceeded by leaf-rosette, slightly to greatly curving;
SCAPE-BRACTS 15-50 cm long by ca. 4.0 cm wide with long filiform blade, imbricate throughout, sheaths erect, blades spreading, red-dish-brown;
INFLORESCENCE 20-40 cm long by 5.0-6.0 cm wide, bipinnate or tripinnate and with two nearly equal digitate branches, dense, cylindric, curving, glabrous;
PRIMARY BRACTS 3.5-4.5 cm long by ca. 5.0 cm wide, orbicular, apex rounded to apiculate, coriaceous, imbricate;
SPIKES 2.5-3.5 cm long by 1.8-2.0 cm wide, ca. 15 per inflorescence, erect, ca. 1.5-2.0 cm apart, having 4 to 10 flowers per spike, sessile;
FLORAL BRACTS 2.2-2.4 cm long by ca. 1.8 cm wide, erect, imbricate, ovate, apex acute, carinate, coriaceous, not nerved, reddish to orange when alive, glabrous without and within;
SEPALS 1.8-2.0 cm long by 0.9-1.0 cm wide, ovate-elliptic, acute, scarcely nerved, glabrous without and within;
PETALS 3.5-4.0 cm long with two inconspicuous scales ca. 1.1 cm long from petal base, green;
CAPSULE ca. 3.0 cm long, distance between flowers ca. 6 mm.
MATERIAL EXAMINED: Espinosa E 355 (CH) epiphytic, Cajanuma south of Loja, Prov. Loja, ca. 2400 m, 7 May 1948; AJC 1131 (US) strongly windswept area, dwarf forest and cloud forest, all branches densely covered with leafy liverworts, tank of bromel filled with water and spongy mass of detritus, km 38 Catamayo-Loja, Prov. Loja, ca. 2500 m, 10 Aug. 1965.
NOTES: From a brief perusal of herbarium specimens of this species one might suspect that it would be adapted especially well to desiccation because of the densely, moderately appressed lepidote, coriaceous leaves. However, it seems to also thrive in very moist areas where the air circulation is abundant such as on windswept knolls or near water falls.
