Asemnantha included one species of low shrubs in southern Mexico and northern Central America.It was similar in many features to Chiococca, but differed from that in its inflorescences with one to a few shortly pedunculate flowers and regularly developed bracts, well developed alyx limbs, and tubular-urceolate yellow to cream-colored corollas (vs. pedunculate, usually branched inflorescences, generally short calyx limbs, and funnelform to campanulate white to pale yellow corollas). The data supporting separation vs. inclusion of Asemnantha in Chiococca were equivocal for some time, and various Rubiaceae genera such as this were separated based on inflorescence and corolla form More recently, the molecular study of Paudyal et al. (2018) found it well supported as nested within Chiococca and the inflorescence and flower form more variable than appreciated in that latter genus.
