If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.

T. Van der Hammen and C. Garcia de Mutis 1966Polyplicate. With a smooth zone at each pole; diameter of this zone ± 10 μ. Size of the grain ± 34 μ long and ± 19-23 μ wide; pollen index relatively variable; exine thicker in the polar areas; number of plicae ± 30-50. Sometimes the exine is open at one of the 'plicae', thus simulating a colpus. The diameter of the polar area of the holotype is about 9 μ, and the proportion of this diameter to the width of the grain is about 0.4.
