Glossary

Saccate

pollen grain with blisters or air sacs.

Scabrate

ref. sculture. Sporoderm with elements less than 1 um high.

Sculpture

sporoderm, observed in its superficial ornaments. Outside pattern of the pollen grain.

Semiangular

distinctive pollen shape in polar view.

Semilobate

distinctive pollen shape in polar view.

Semitectate

pollen sporoderm with discontinuous interrupted tectum.

Sexina

external side of the exine.

Simplibaculate

ref. sculture. Reticulated sporoderm with one row of bacula along the reticulum.

Spheroidal

pollen grain with the axes length more or less equal (P/E = 1).

Spinulose

sporoderm with short and narrow echinate elements.

Sporoderm

pollen grain wall formed by the exina (outer layer) and the intine (inner layer).

Stephanocolpate

ref. aperture. Pollen grain with more than three colpi arranged along the pollen equatorial belt.

Stephanocolporate

ref. aperture. Pollen grain with more than three colpi and pori arranged along the pollen equatorial belt.

Syncopate

ref. aperture. Pollen grain with colpi anastomosed (fused) in polar area.
