Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| T. Van der Hammen and C. Garcia de Mutis 1966 | Monocolpate, foveolate to reticulate, size of pollen grain 40-60 μ. The diameter of the lumina is 0.5-6 μ. Colpus long, in general longer than the visible length of the grain, sometimes nearly circular, in some cases the colpus is a little bit shorter than the length of the grain. The size of the individual lumina is very variable. It is possible to distinguish at least two varieties, although it seems that there exist intermediate types between both: one with foveolate sculpture and the other with reticulate sculpture. |
