| English abstract | Pollen grains from seven collections of C. echinata were examined. The pollen material was acetolysed, measured, described, and digitally photographed by light microscopy and, microscopy scanning electron. Pollen grains of C. echinata are medium to large in size, suboblate to oblate spheroidal, circular amb, 3-brevicolporate, colpus with a wide microreticulate margin, formed by the thinning of sexine at that region, endoaperture lolongate, exine reticulate, heterobrochate |
