Abstract

Pollen of Setchellanthus caeruleus was studied by light, scanning electron, and transmission electron microscopy and found to differ profoundly from that of potentially related families such as the Brassicaceae, Capparaceae, Caricaceae, Cistaceae (Helianthemum canadense, here re-investigated and found to have pollen shed in tetrads), and Limnanthaceae. These differences support the segregation of S. caeruleus into a new separate family.
