Range: Tepui region of Venezuela, Guyana, and extreme northern Brazil, possibly Trinidad and Tobago
This South American miniature is a fairly widespread but enigmatic species, named after Kaieteur Falls of Guyana and found throughout the Gran Sabana and tepuis of the Venezuela-Guyana border (with some reports possibly of it growing on the offshore island of Trinidad and Tobago, though this may be a nonnative introduction). Plants grow from 460-2400 meters in elevation, where they inhabit sandy seeps or mosses growing across rocky outcrops typically in permanently wet environments (though it may be able to resprout from roots in seasonally dry locations). This species develops a prostrate rosette (rarely on stems up to 2 cm high) approximately 1-3 cm across on average, with highly spatulate leaves bearing prominent parallel abaxial-indumentous petioles and broad rounded to semi-oblong (wider than long) lamina. Coloration can be olive green to solid crimson. Inflorescences reach only a maximum of 7 cm in height, often far shorter, and are typically prominently covered in stiff white hairs or small glandular trichomes. Stalks may bear up to 5 (though not uncommonly only 1) 0.5-1cm wide white to pink flowers with broad ovate petals. A somewhat unique feature of this species is the development of the seed pod, which when ripe opens facing upward in a cup-like shape, releasing seeds via rain impact. This species can be distinguished from its relatives (particularly D. felix) by its more oblong rather than circular lamina, pilose inflorescence, and capacity for a larger number of flowers per inflorescence.
Cultivation: Grow in a relatively well aerated peat-based soil (1:1:1 peat/perlite/sand often works), kept moist to even wet most of the year, and with temperatures of 70-90°F daytime, 50-70°F nighttime, year round (highland tepui locales may require cooler conditions to thrive). Sow seeds on soil surface, and grow in strong artificial light to full sun.
Lifespan and reproduction: perennial. Reproduces through seed, but may also be grown through cuttings.
