Short communication: Pollen morphology of Cyanella species (Tecophilaeaceae)

The pollen wall ultrastructure of eight species of Cyanella including one species (C. amboensis) thought to have affinities with Conanthera was investigated. Pollen in all eight species is monosulcate, heteropolar, operculate (except in C. alba, which lacks an operculum) and with a tectate-columellate pollen wall. Despite the similarity of pollen, two groups within Cyanella are distinguished by differences in habitat and floral morphology.
