Notes: This species is characterized by its densely strigillose to hirtellous leaves and stems; several- to many-flowered, pedunculate inflorescences that characteristically are short and rather congested when flower beings and then develop 2-4 monochasial, often prolonged axes; tubular, shallowly lobed, rather well developed calyx limb; corollas about 14-16 mm long; and capsules 4-34 x 2-4 mm. On dried specimens the elongated inflorescence axes often have the developing fruits arranged in a characterisic, apparently distichous arrangement. Joosia dielsiana is known only from Amazonas Province in northern Peru, but is frequently collected in this region.

Joosia dielsiana is simliar to Joosia pulcherrima, which has somewhat larger flowers (corolla 20-30 mm long), usually longer capsules (15-100 mm long), and inflorescences that remain in a rather small form. Joosia pulcherrima was included within the circumscription of Joosia dielsiana by Andersson (Andersson & Taylor, 1994) in the Flora of Ecuador, but subsequently in a revision of Joosia (Andersson, 1997) he separated these and reported only Joosia pulcherrima from Ecuador. Joosia dielsiana is similar to Joosia umbellifera, but can be separated by the calyx with a longer tube and the frequently markedly distichous-appearing arrangement of the developing fruits; Joosia dielsiana apparently replaces Joosia umbellifera in this area.

Distribution: Wet forest vegetation at 200-650 m on eastern slopes of the Andes in northern Peru (prov. Amazonas).
