Plant 6-9 din. high. Leaves about 6, some much reduced, ovate, abruptly acute, brown, other leaves 6-9 dm. long, petiolate; sheaths triangular-ovate, brown-lepidote; petioles 2 dm. long, channeled, armed with small dark recurved spines, tomen- tose-lepidote beneath; blades lanceolate, acumi- nate, 5 dm. long, 5 5-60 mm. wide, entire, glabrous. Scape erect, stout, elongate. Scape- bracts with a large ovate base and long acumi- nate blade, subglabrous, especially the upper ones brownish purple. Inflorescence simple, sub- spicate, obtuse, densely many-flowered, 2-3 dm. long, 3-5 cm. thick. Rhachis finely tomentose- lepidote, wholly concealed. Floral bracts broad- ly ovate with a narrowly triangular divergent blade, 5-7 cm. long, much exceeding the sepals, glabrous, deep reddish purple to bright red or rarely yellowish. Flowers subsessile. Sepals ob- long, abruptly acute, short-mucronate, 25 mm. long, narrowly winged near apex, minutely lanate. Petals linear, broadly acute, exceeding the stamens, unequal, to 77 mm. long, pale yellow, bearing a large bidentate scale at base. Ovary 3/4 superior. Ovules long- caudate.

Note
|
Pitcairnia Lamarcheana has been separated as a species and then as a variety on irs pale yellowish floral bracts, but it is known only from cultivation and it is not possible to say whether this difference is really significant.
