Original diagnosis/description

Anther dithecate, tetrasporangiate, narrowly elliptical. Pollen small, almost circular in equatorial outline, monocolpate, Colpus extending beyond the full length of the grains, but not dividing the grain into two halves. Exine semitectate-reticulate and columellate. Reticulum heterobrochate with irregular lumina and muri with occasional open ends. Muri smooth with slightly rounded profiles, supported by short, scattered columellae. Colpus margin distinct with reticulum continuing to the margin and the colpus margin delimited by the continuous marginal muri of the reticulum.


From Latin: longus and colpus referring to very long colpus of the pollen grains.
