Pollen of Klotzschia (Umbelliferae): A Possible Link to Araliaceae
Preview not available

Abstract

The sexine stratification of the pollen of Klotzschia (Umbelliferae) is strikingly similar to that of many Araliaceae, forming a possible link between the putative ancestral araliaceous type and more specialized umbelliferous types. Among the three species of Klotzschia, the tectal surface sculpture of K. rhizophylla appears to be intermediate between that of K. glaziovii and K. brasiliensis.
