The unique type of pollen grain of Dasistoma (Macranthera-Agalinis clade; Orobanchaceae): implications for taxonomy

Grana, 2022
Pollen morphology of six species from the Macranthera-Agalinis clade (Orobanchaceae) was studied using both light microscopy and scanning electron microscopy. Pollen grains are (2-)3(4-)-colpate, 3-brevicolpate and 4-, rarely 6-porate, obtate to prolate (
