Derek Butcher ... "Heather: You have set a puzzle here because T. incarnata is known for its long stems and rose flowers! BUT I have a gut feeling this originated with Pedro and a KK shipment years ago. Therefore, I think you should look at T. incarnata var margaritacea. It is rare! Check it out with the enclosed description."

The alleged locality of Mexico is probably an error.

Notes from Gilmartin 1972
The length of the plant may vary from as short as 15 cm to as tall as 75 cm including the well developed stem in T. incarnata H.B.K. However, the inflorescence parts, the leaf dimensions, and shape are much less variable. The altitudes at which this species has been collected to date in Ecuador are from ca. 2000 m to 3000 m. The stamens are included as is the stigma but often the anthers reach the apices of the petal blades. Vegetative propagation in its natural habitat is common. The above 32 specimens bear witness to the abundance of T. incarnata in portions of the northern and central Ecuadorian Andes.
Harry Luther comment 30/3/1993
T. incarnata seems to intergrade with T. queroensis. Your photo appears to represent something along this cline.
Tillandsia incarnata var. margaritacea A. Roguenant & Raynal-Roques, J. Brom. Soc. 54(4): 180-1. 2004
TYPE: Ecuador. Tungurahua:Ambato, 2300-2800 m alt, epiphyte on Schinus molle and Caesalpiniaceae, 12 May 2001, Albert & Claudie Roguenant & Aline Raynal-Roques 0177 (Holotype: SEL). Figures 36, 37.
A varietate typica sed bracteis scapigeris griseo-viridibus, inflorescentia simplici, spicis brevioribus, subviridi-griseis, 5-8 flora, bracteis florigeris subviridibus, et petalis margaritaceus differt.
Plants in dense tangled masses;
stem branching, its branches to 10-35 cm long,
roots present on young plants.
Leaves densely polystichous, spreading, 6-15 cm long, gray, covered with appressed or slightly spreading scales;
sheaths ovate, indistinct, sometimes tinged with brown;
blades suberect to spreading, narrowly triangular, filiform-attenuate, usually involute toward the apex.
Scape terminal, straight or slightly curved, about 2.0-2.5 mm in diameter, 10-30 cm long, lepidote or glabrous;
scape bracts densely imbricate, elliptic, chartaceous, the lower gray green, with long filiform blades, the upper acute or apiculate, pale green to cinereous, apex cinereous, sometimes slightly rosy.
Inflorescence simple; spike lanceolate or linear, flat, 5.0-7.5 cm long, often arched, pale greenish gray loosely 5-8 flowered, internodes 7 mm long, rachis nearly straight, subquadrangular, lepidote to glabrescent.
Floral bracts and scape bracts alike, imbricate or the lowest slightly divergent, elliptic, apiculate, 1.5-2.2 cm long, exceeding the sepals, ecarinate, chartaceous, with a longitudinal nerve, densely lepidote, pale green, apex generally more beige;
Sepals lance-elliptic, acute, about 1.4 cm long, with a longitudinal nerve, lepidote, carinate and connate for 1 mm;
petals narrowly elliptic, erect or nearly so, tortuous, pearl-white, 2.0-2.5 cm long, claw 3 mm wide, ended with a lanceolate blade 5-6 mm long, obtuse;
stamens included, 18 mm long,
filament pure white, 0.4 mm in diameter, bearing a straight yellow anther, 3 x 0.2-0.3 mm.
Pistil 16 mm long;
ovary egg-shaped, clear green, glistening, 4 mm long, 2 mm wide;
style white, spindly, 10 mm long, 0.4 mm thick;
stigma 2 mm long, white, papillose inside.
The new variety was observed growing mixed among populations of the typical variety, but also in large populations by itself. Individuals of the new variety tend to be smaller in stature and always have pearly-white petals. They are found as epiphytes on Schinus molle (Anacardiaceae) and on vertical cliffs. The species name refers to the pearl-white petals.
