Pollen morphology - Open Access .click

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.

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.

Pollen Morphology as an Index to Plant Relationship. I. Morphology of Pollen

Botanical Gazette, 1925
The paper reports a study of pollen morphology in numerous genera of about eighty families represented in the flora of Colorado, together with a small number of familiar exotic forms. A discussion is given of the general interest of pollen, with methods of study and preservation. Pollen shapes are described, as well as markings, size, color, stickiness,

Trends in pollen morphology: 6th bibliographic index to pollen morphology of angiosperms

Grana, 1991
Abstract The sixth volume in the series of bibliographic indices to the pollen morphology of the angiosperms initiated by G. Thanikaimoni in 1972 is analysed with respect to the three main instruments used for the description of the pollen grains, viz, light microscopy, scanning electron microscopy and transmission electron microscopy.
