NOTES
Date de publication : Linnaea, 23(4): 451. 1850 [08/1850, fide TL-2, 10744, voir p. 197].
Distribution : Espèce mal-connue à la suite d'innombrables confusions, actuellement connue de manière certaine seulement de Guyane française, et du Suriname; données à confirmer au Guyana, et probablement présent en Amapá et dans le nord du Pará (GBIF).
Statut biogéographique : Espèce mal-connue, en Guyane française, en plus du type, une dizaine de collectes connues.
Taxonomie : D'après Delprete (Taxon, 64(3): 601. 25/06/2015): "Coffea paniculata has been overlooked by previous specialists (e.g., Bremekamp, Steyermark), probably because it was not readily assignable to Coussarea or Faramea, or confused with Coussarea paniculata (Willd.) Standl. because of the same specific epithet (e.g., Steyermark, 1967: 367). According to Aublet’s (1775) accurate description, Coffea paniculata is characterized by having large, pointed stipules, fragrant (jasmine-like) flowers, white corollas, stamens attached at the middle of the tube with short filaments, bluish style branches, 2-seeded or rarely 1-seeded (by abortion of 1 ovule), bluish berries, and when 2-seeded, the 2 seeds adpressed against each other, planoconvex, and with a longitudinal ventral sulcus (seed globose when 1-seeded). Because of these features, this taxon was placed in Faramea by Bentham (1850) and in Coussarea by Lemée (1954). The bluish berries, commonly 2-seeded, and the pointed stipules indicate that this species belongs to Faramea (vs. commonly 1-seeded, whitish, yellowish or purple fruit, and triangular stipules in Coussarea). In addition, Aublet’s description and illustration (1775: 152–154, fig. 58) and examination of the type specimens, clarified the identity of this species, which is here maintained in Faramea with the binomial proposed by Bentham (1850). Previously this species was commonly known as F. torquata Müll.Arg. Comparison of the types of F. torquata and Coffea paniculata, and examination of collections throughout the Amazon Basin, showed that there are no morphological differences, and they are here treated as synonyms."
