Abstract
The pollen wall ultrastructure of the primitive Angiosperm Lactoris fernandezianaPhil. (Lactoridaceae) is described. The monosulcate aperture, granular wall structure and sacci (all primitive features) suggest placement of this family in the Magnoliales. Pollen of Lactoris is compared to fossil dispersed pollen from the Lower and lower-Upper Cretaceous. The fossil pollen shares characteristics which are restricted to the Lactoridaceae suggesting that this family was present during the early Cretaceous.
