Pollen morphology ofLactoridaceae

Plant Systematics and Evolution, 1986
The pollen wall ultrastructure of the primitive AngiospermLactoris fernandezianaPhil. (Lactoridaceae) is described. The monosulcate aperture, granular wall structure and sacci (all primitive features) suggest placement of this family in theMagnoliales.

Evolution of Pollen Morphology

Science, 1991
Over evolutionary time, the morphology of angiosperm pollen has evolved toward an increasing number of apertures, among other things. From a neo-Darwinian point of view, this means that (i) some polymorphism for aperture number must exist and (ii) there must be some fitness increase associated with increasing the aperture number.
