Aperture Number- An aperture refers to the thinner regions within a pollen grain. These regions will differ in color from the rest of the grain. | Aperture Type- Region of pollen grain that is thinner, and differs in ornamentation and color. | Bloom Time | Dispersal Unit- The morphological unit in which pollen grains are shed. May be singular monad , or in groups dyad, tetrad, polyad | Ornamentation- The general pattern, or texture of a pollen grain. | Shape | Size | Tectum- The outer layer of the pollen wall, which will appear like a rim around the grain.

2. Dispersal Unit- The morphological unit in which pollen grains are shed. May be singular monad , or in groups dyad, tetrad, polyad    [Explain]

349Monad- A pollen grain in the form of a single unit.    1Polyad    14Tetrad- A group of four united pollen grains. NOTE- fourth component of grain may be faint, or difficult to locate in a given image.   




3. Aperture Number- An aperture refers to the thinner regions within a pollen grain. These regions will differ in color from the rest of the grain.

4. Aperture Type- Region of pollen grain that is thinner, and differs in ornamentation and color.    [Explain]

97Colpus- An elongated aperture that is often pointed in the center.    154Compound- Contains both two or more apertures together. Often a pore and a colpus.    13Inaperturate- No aperture present    1Irregular    46Porate- A circular or elliptic aperture within a pollen grain    38Sulcus- An elongated, latitudinal, aperture.   







5. Ornamentation- The general pattern, or texture of a pollen grain.    [Explain]

5Clavate- Club shaped element. May be difficult to differentiate from granulate/perforate.    89Echinate- Pollen with spines or spiked elements running along the surface of the grain.    115Granulate/perforate- Small, dotted elements less than 1um in size.    1Irregular    4Lophate- A raised outer exine creates a pattern of ridges lophae and depressions lacunae .    21Psilate- Smooth surface    120Reticulate- A network like pattern across the surface of the grain.    36Striate- Generally parallel elements running along surface of the grain.   









6. Tectum- The outer layer of the pollen wall, which will appear like a rim around the grain.    [Explain]

2Atectate- Pollen grains lacking a tectum, or outer pollen wall.    258Eutectate- Pollen grains with a continuous tectum, or outer wall.    81Semitectate- Pollen grains with a discontinuous tectum, or outer wall. The tectum is instead separated into parts.
