Discussion:

Richeria grandis var obovata Mull.-Arg. in DC., Prodr. 15(2): 468. 1866.

Type. “Ad flum. Guainia v. Rio Negro supra ostium fluminis Casiquiari. Spruce 3526." (Isotype in NY) Terr. Amazonas, Venezuela. (Not “Brasilia Septemtr.”)

Pax describes this species as having “Capitula florum male pedunculo 2 mm longo suffulta.” This may be misleading. It is definitely sessile on the type. Muller-Argoviensis’ original description is more correct: “glomerulis florum multiflorum breviter pedunculatis superioribus sessilibus.”
