Echimonocolpites ruedae
Taxonomy
Monocolpites ruedae was named by Van der Hammen (1954). It is considered to be a form taxon. Its type specimen is Slide C-1-23 Col. S.G.N., Suesca, Maestrichtian, Zone C), a seed repro (Pollen grain), and it is a 3D body fossil.
It was recombined as Echimonocolpites ruedae by Van der Hammen and Garcia de Mutis (1966).

|---|---|---|
| T. Van der Hammen and C. Garcia de Mutis 1966 | The holotype (Slide C-1-23, Col. S.G.N., Suesca, Maestrichtian, Zone C) measures 27 μ, is transparent (exine almost colorless), slightly flattened at one side, and shows well-defined echini of ± 1-3 μ long. The colpus is not very well defined. In some specimens of the Paleocene (Slide F-V-47, Col. S.G.N.), the spines are densely placed and they seem to radiate in a very regular manner from a point located in the centre of the grain; for the rest they are identical with the holotype of E. ruedae. Although there is perhaps justification in establishing a variety, for the time being we shall refrain from creating it. |
