Latin Diagnosis - Frutex parvus ad 5 dm altus; ramis ramulisque teretibus tenuibus adscendentibus, ramulis juvenilibus subtiliter puberulentibus in ramis maturis epidermi exfoliato. Folia imbricata, conferta; laminis marginibus puberulentibus exceptis, glabris, lineari-lanceolatis, vulgo 5-6 mm longis, 12-15 mm latis, acutis brevissime cuspidatis; dorsali late caniculata, area triangulare separata brevissime ad 0.3-0.4 mm longa; petiola ca 1.5 mm longo anguste marginato. Flores pauci ad ramis apicibus congestis; pedicelhs ca 0.5 mm longis, puberulentibus, axillaribus, 1-2 bracteis foliaceis subtensis; sepahs liberis, 4-5, anguste lineari-lanceolatis, ca 6 mm longis, 1 mm latis, marginibis ciliolulatis; petalis 4-5, albidis, anguste linearioblongis, obtusatis, 8-9 mm longis ca 1.5 mm latis; staminibus 4-5, filamentis ca 5 mm longis teretibus proxime sub ovario affixis, antheris ca 0.9 mm longis, ovalibus, emarginatis; ovario valde tuberculato, (4-)5-loculari, stylo juniori ca 2 mm longo, nee capsula nee seminibus visis.

Discussion:
Type. VENEZUELA. Edo. Bolivar: summit central-western portion of the Meseta de Jaua, Cerro Sarisariiiama, 4 degrees 45 minutes N lat, 64 degrees 26 minutes E long, 60 km NE Mision de Campamento Sanidad, Río Kanarakuni, 2000 m alt, 22-27 Mar 1967, subshrub 0.5 m, petals white, leaves closely ascending, dull green, locally frequent along rocky stream, Steyermark 97918 (holotype NY, isotype VEN). Ledothamnus jauaensis is known only from the type collection, but was observed by Steyermark to be locally frequent in the humid area of Sarisariñama traversed.
