Type. Upper Mazaruni River Basin, Kako River, British Guiana, alt. ca 1220 m ; leaves medium green with red spines and white hairs along margin, very stiff and brittle; bracts of inflorescence orange-red; perianth yellowish-white; locally dominant on vertical cliff faces, main peak of Karowtipu, 29 Sep 1960, S. S. & C. L. Tillett 45557 (holotype NY).

Because of its blunt cucullate sepals Navia farinacea appears to be related to N. latifolia L. B. Smith, but its leaves are glabrous except for the barbellate spine-axils instead of being cretaceous beneath like the latter.
